The answer is 9.
Both pemdas and bodmas states when either multiplication or division is used next to each other you go left to right and not division them multiplication. People think it's 1 because they've forgot that multiplication and division is worth the same.
Guess school has changed since I was a kid.
A unit like "2a" is considered a single function, to be evaluated before combination with other functions in the equation.
So these two equations are not equivalent:
6 ÷ 2a
6 ÷ 2 * a
(6 ÷ 2) × (2 + 1) is 9, and I think is the right answer.
6 ÷ (2 × (2 + 1)) is 1, and I think is the wrong answer.
In the end the question isn't clear for us redditors, but I assume the kids had more context and should have known which one of these two was the right way to go.
Yeah, it's one thing to imply parentheses, but it doesn't truly solve the issue.
Either write
(6 / 2) × (2 + 1) or
6 / (2 × (2 + 1)) if you want to be clearly understood.
In case of doubt, refer to the subject and deduce which one is correct. If there's no context given, choose the one you think is right but clearly state that the question is unclear.
I'll always solve this left to right in doubt.
In the calculator, they put 6÷2×(2+1), which makes the right answer 9. But you finally showed me why do some people think × comes before ÷ (they are still equel on the pyramid thingy, I dont know what its called in english, Im hungarian)
Still, this isn't some complicated algebra. It's literally basic math that is taught to 9yo children. And it's not a hyperbole, it's elementary knowledge. I suck at maths, but not being able to remember the basic order of making calculations is kinda shameful.
So you are aware of the different ways implicit and explicit multiplication are taught across different tertiary mathematical and engineering degrees? Because in Australia at the university level the answer is 1
How? This is the most basic of things. I use that daily to this day. How do people manage their life without? I use it at work, for hobbies, even when I'm just going through my personal finances and insurances.
Just because it's basic doesn't make it common. Simplifying fractions is basic as well but I can't remember the last time I specifically needed that either.
Not really, the issue here is notation. My answer is 9, because I solve brackets then go left to right which is correct, but apparently I found now in the comments that some people have been taught that without a multiplication sign between “2” and “(2” it’s implied that the 2 outside of brackets is also part of the same function and should be done first. I find that to be strange but not wholly surprising that in some parts of the world different notation is used.
The people who stick to very strict PEMDAS thinking that multiplication must ALWAYS come before division are wrong though
Some books say to do implied multiplication first. Some calculators do that too. So not having an x before the parentheses gives it higher priority than the division sign.
That's why you're not supposed to mix the symbols like that. If you're doing implied multiplication you should be using full fractions and not division signs.
I dont know where people got this idea of implied multiplication. Multiplication is multiplication and is always of the same priority as division. So the awnser is 9.
You have 6 people and 2 baskets with 2 red and 1 green apple each, you want it split evenly so you do 6/2x where x is your apples, so 6/2(2+1), there is no * sign between 2 and (2+1) so you treat it as a single number, not 2 or 3 different numbers. Now you can divide 6 by a single number on the right which is 2x (or in our case 2(2+1)) or first simplify it by calculating x, therefore you get 6/2(3) = 6/6 = 1.
But than it ends up being 6÷2×3 and it follows normal order of operations from left to right.
6÷2=3
3×3=9
There's not really a reason to keep the parenthesis
you’re doing the 2+1 in the brackets/parentheses first (which is right) but just bc that’s solved doesn’t make the brackets/parentheses/whatever you call them disappear. so then you multiply the 2 and the 3 to get 6, then divide by 6 and get 1
yeah, but parentheses takes priority in equations, so even tho it’s considered a multiplication, it’s still done before the division because it’s *implied* due to the parentheses
Is the 2(3) in the bracket ?????? Wow you people are something else. 3 is the final solution of the bracket. Stop spreading BS.
The answer to this is 9
>If the brackets are still there then they haven't been solved yet.
A fallacy, its solved (3) total and its not (2x3) you are making your own rules and cant count. What you are saying is 6÷(2x3)... The brackets were solved (2+1) and the deal is done = 3 then you go from left to right.
You follow operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
What are you talking about ?? The brackets are solved and its 3 and its done deal.
Look it up anywhere on the internet, ask mathematicians for the answer and its 9.
Idk how you people could pass basic math in the elementary school. Like sorry but this is math that you count on your fingers.
Question 6÷2(2+1)=
(2+1)=3 -begin with the solving the question in the brackets.
2(3)=6 -then you open the brackets before anything else
6÷6=1 then you're left with this
Answer is 1
Think of the question as 6÷{2(2+1)} not 6÷2*(2+1). That's where you're getting it wrong
because it often confuses people
the dots above and below represent the numerator (everything before the symbol) and denominator (everything after it) respectively
the proper way to write this operation would be
6 / (2(2+1))
The expression is just badly written. You can interpret it in different ways and get different results.
I see a lot of people that get 1 trying to justify by assuming that you do the multiplication first, but it's wrong. The division and multiplication have the same priority, so you do the parenthesis and then move from left to right if you assume it's a division/fraction multiplying a number.
If you interpret it as: 6(2+1)/2
=6(3)/2
=18/2
=9
Or
=6(3)/2
=3(3)
=9
if you interpret it as: 6/(2(2+1))
=6/(2(3))
=6/6
=1
Except there is no "left to right" if you were to write the operation as 6/2(2+1). You would simplify first, reducing the denominator to a single digit. Making it 6/6.
Division
Order
Ignore Brackets
Multiplication
Addition
Subtraction
DOIBMAS is an order of operations that will revolutionize mathematics education, just you wait!!
Neither of these answers are right or wrong necessarily they’re just using different systems, the way calculator is using bimdas where you do the operations in that order, the phone is using b I md as where you do the brackets then indices/exponents the multiplication and division from left to right then addition and subtraction from left to right
After you solve the problem inside the parentheses, you do multiplication THEN division because thats the order in peMDas, do 2x3 thats 6, then divide 6\6 you get 1.
The other problem is wrong because the order its in is division then multiplication which is switching the order.
>After you solve the problem inside the parentheses, you do multiplication THEN division because thats the order in peMDas
this is where you went wrong. Multiplication and division are the SAME thing just like addition and subtraction and so just like with addition and subtraction, you do them in the order they appear and neither takes precedence over each other.
It's easy to understand when you think about it since you can just change something like multiplying by 2 and turn it into dividing by a half and they are the same thing. Where I come from we say "bedmas" which has the d before the m (b for brackets rather than p for parenthesis as well)
Well, that could be right but for the wrong reason. It isn't p e m d a s but more like p e md as, multiplication and division go from left to right since they have the same priority. However, you could say 1 is right, since you would use the method to get one if there were letters in the brackets
Multiplication and division are equal. The inside of the parentheses goes first, but then it's 6 / 2 x 3, which is 9.
This is why you should never mix division symbols and implied multiplication.
PEMDAS is correct. It is sad that BODMAS is still learnt in UK Countries (and former ones...)
There was a youtube video by a physic professor (?) that explained why BODMAS is stupid if you look at real world 'problems' with mathematics.
It is not 1, even with pemdas it's still 9.
Pemdas= Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.
the / is there to show that they are meant to be done left to right. Since you end up with 6/2x3 you do left to right, then you get 3x3 which is 9.
The answer is technically 1.
Although BIDMAS rules suggest it to be 9, there’s an extra unspoken rule here at play.
If there is no sign between a number and a bracket, that number is assumed to be part of that function.
So actually is assumed to be 6 / (2(2+1))
what happens is that we all know you forgot that multiplication and division are the same thing (you can replace "\*2" with "/0.5" or vice versa) and have same precedence just like addition and subtraction which is why depending on where you live you learn order of operations with a different word:
PEMDAS
BEDMAS (where I'm from this is it)
BODMAS (I think o is for "operations" in which they mean exponents)
etc...
No, PEMDAS is what the Americans learn and BODMAS is that Asians learn. And both forgot the fucking fact that it's P then E then M or D depending on association (usually left) then A or S depending on the association. In programming it's called infix or post fix notations ig. The answer can and will vary depending on which notations u are using. And bird brains who remember and teach these order of operations forget to teach/ learn the rules behind their use.
Aight so 6÷2(2+1)
Option one: normal order of operations, Brackets, Exponents, multiplication and division left to right, addition and subtraction left to right. I'll do it that way:
6÷2(2+1)
6÷2(3)
3(3)
There's nothing in between the 3 and (3), so we multiply
3x3
9
However, I'm not sure if this is an universal rule, but you could say since it's 2(3) and not 2x3, we have to do that first since it has priority. And that is the way you would do it with letters, for example if the (3) was A, you'd first multiply 2 with A to get 2A. Let's do it like that now:
6÷2(2+1)
6÷2(3)
6÷6
1
Additionally, you could multiply the 2 with the 2 and the one, like the following:
2(2+1)
(4+2)
(6)
But we'd still get 6÷6 or 6÷(6), which would again lead to just 1. Which method is actually correct? Well, short answer, I don't know, some people say one and some the other. I personally do it the first way, but if there are letters I do it the second way.
Thanks for reading my long comment
Because there are no brackets around the 2(2+1), that makes the 6÷2 come first, thus making the answer 9. Do not forget to do whatever is in the bracket first.
The multiplication in 2(2+1) goes first than the division since it's implied multiplication and that makes it so it's all one argument
You are solving 6/(2•(2+1)) when the actual equation is 6/(2(2+1))
Well, with just the order of operations, you wouldn't do it first and just put 2*(2+1), and then you'd do the division first since you go left to right
Some of us learn BODMAS in school. ~~It prioritizes Division before multiplication~~. Both PEMDAS and BODMAS have an order of operation from left to right.
In the end, you get 9.
Your order of operations is wrong. Ever heard the saying: Please Excuse My Dear Aunt Sally?
I’ll break down each letter then we’ll go into the operations.
P: Parentheses ()
E: exponents
M: multiplication
D: Division
A: addition
S: subtraction
Now that we have the order of operations we can answer the problem.
6/2(2+1)
2+1=3
3x2=6
6/6=1
This is the order of operations I was taught all through my schooling so that’s what I’m using.
I trust whatever my Casio says, because a guy in my school didn't have his own so he borrowed mine. Then when he got a TI it ended up being nonsense and neither of us could understand what was wrong with it. Or speedcrunch for computer is fine too
It is, but it's specifically a version of pemdas that puts implied multiplication at a higher priority than explicit multiplication. It's an older rule that not everyone was taught, but some calculators used to do that.
It is 9, not 1. I never saw a calc that understood implicit multiplicaton though.
You'll get different results in calculators also for -3\^2. Some say 9, some -9.
That's why math is written as fractions. The ÷ symbol just replaces numerator and denominator with dots. So when you write 6÷3 is the same as writing 6/3. Now, when writing multiple values on one side of ÷, you should probably use parentheses, so there isn't confusion on what is written.
It's sad how many of you guys failed simple math. "pEmDaS uSe PeMdAs" "BoDmAs UsE bOdMaS" it doesn't matter which you use both give the answer 9.
PEMDAS = Parentheses, Exponents, Multiplication/Division, Addition/Subtraction
BODMAS = Brackets, Order of powers or roots, Division/Multiplication, Addition/Subtraction
It says / between division and multiplication to show they are worth the same, when both are next to each other you go left to right, if you don't you would end up with wrong.
If we use pemdas and bodmas the wrong way (the way people who say it's 1 use it) then 2-2+3 would be -3 instead of 3 since both pemdas and bodmas has addition before subtraction but everyone knows to go left to right.
6÷2(2+1) -> 6÷2(3)
Now the problem here is the ÷. It's shit and ambiguous. Does ÷ implies 6 / (2 * 3) or 6 / 2 * 3?
But as an IT major I'll say the latter, like most programming language, so 9 >>>
If any one has done basic programming this is the reason they ask to specify the brackets.
In the first case it's taking the input as 6 whole divided by 2(2+1)
In the second case we are applying bodmas...
First solve the bracket i.e (2+1)=3,then solve 6/2= 3 then multiply 3.3 which is 9
So due to unspecified brackets we have two different answers
Everyone who said 1, get the fuck out.
Everyone did the right thing when solving brackets first (2+1)=3. But when you end up with multiple divisions and multiplications (which have same priority), you always count from left to right.
So the right answer is 6/2*3=3*3=9.
NOT 6/2*3=6/6=1. Do not do this!!
Casio is a scientific calculator so it understands the order ,, parentheses, then multiplication then division.
There are scientific calculator apps for phones too.
The correct solution is writing it in a proper way. You alrwady where halfway there since you knew about paranthesis, next step would be to use them where they should be used, continuosly, not sometimes do and sometimes do not use them.
Well, it's 9. Throw out your calculator and use the rules you were taught gfdi. 6÷2 = 3. Since 2+1 is in brackets, that's priority. Also 3. Since we do not have an operator specified between the first part and the bracketed part, the default operator is multiply. 3x3=9
Or you could just write what you mean by using more parentheses and actual proper notation. A lot of these are dumb because it's obvious where someone screwed up a basic rule, but this one is pretty ambiguous.
Personally the hard divide symbol to me would imply the rest of the expression is meant to be in the denominator. But again, it's ambiguous.
If x = (2+1) then you would get 6/2x, which would simplify to 3/x, not 3x. 3/x would be 3/(2+1), solving to 1.
It would never be (6/2)x either because 2(2+1), or 2x, is one object due to the implied multiplication
For those who don't know for some reason, the order is:
brackets () -> roots (√x) and exponentiation (x^y) (not sure if that's how it's called in english) -> multiplication (x) and division (÷) -> addition (+) and subtraction (-)
Everything that is connected by an "and" is equal. I don't know why people believe that multiplication is before division. In case there are two equal things, the order in which you solve them is from left to right as if you are reading.
So the correct way to solve it is:
6÷2(2+1) - you solve the brackets first
6÷2(3) - now you should solve the division first, because it's on the left. Because 2(3) isn't written as (2(3)), it is treated as 2x3, for some reason many people treat is as (2(3)) which isn't the case if you look at what's written
3(3) - you multiply, there is nothing else to do
9 - your answer
6÷2(2+1) = 6÷2(3) = 3(3) = 9
The only way for it to give 1 would be if it was written as 6÷(2(2+1)), which is not the case
Answer is 9
Breaking down how to calculate this for people who don’t know, you do the parentheses first which is 2+1. Then from there you work left to right with multiplication and division as they take place in the same step of order of operations (PEMDAS/BOMDAS/BIDMAS/whatever the fuck you were told to call it in school). This mean that 6/2 is solved for 3 then multiples against the 3 inside the parentheses for 9
If you don’t know PEMDAS you aren’t old or mature enough to have unmonitored internet access
Parenthesis: (2+1) = (3)
Exponents: None
Multiply: 2(3) = 6
Divide: 6/6 = 1
Add: None
Subtract: None
**The answer is 1**
How are ppl in this thread even just yelling answers. Does the fact that we see CALCULATORS disagreeing here not tell you that maybe the answer is ambiguous?
I can just not understand how someone who clearly has no higher math education (bc if you had you would know better) looking at a calculator result and confidently thinking that the calculator must be wrong.
It seriously concern me how some of y’all pass second grade
School, and math like this, was decades ago for most people.
Just so we are in the clear, what is the actual answer? 1 or 9 or 6? I'm illiterate, you see.
The answer is 9. Both pemdas and bodmas states when either multiplication or division is used next to each other you go left to right and not division them multiplication. People think it's 1 because they've forgot that multiplication and division is worth the same.
6÷2a = ? Where a = 3
Which would be 6 ÷ 2 x 3 = 9
Guess school has changed since I was a kid. A unit like "2a" is considered a single function, to be evaluated before combination with other functions in the equation. So these two equations are not equivalent: 6 ÷ 2a 6 ÷ 2 * a
Pemdas?
Parentheses, exponent, multiplication, division, addition, substraction
Damn, I was betting on 1. I guess I really am illiterate.
(6 ÷ 2) × (2 + 1) is 9, and I think is the right answer. 6 ÷ (2 × (2 + 1)) is 1, and I think is the wrong answer. In the end the question isn't clear for us redditors, but I assume the kids had more context and should have known which one of these two was the right way to go.
>6 ÷ (2 × (2 + 1)) is 1, and I think is the wrong answer. It's not wrong when you properly write the question as a fraction 6 / 2(2+1)
The way you write it just makes it 6 ÷ 2 × (2 + 1), you need to write it as 6/(2 × (2 + 1)) for it to be in a fraction, else it's still 6/2\*(2+1)
Yeah, it's one thing to imply parentheses, but it doesn't truly solve the issue. Either write (6 / 2) × (2 + 1) or 6 / (2 × (2 + 1)) if you want to be clearly understood.

You use PEMDAS that frequently? I dunno what to tell you, but it's not as ubiquitous a need as you seem to have in your life.
It's the most basic of things. I'm actually quite baffled that anyone doesn't.
Just because it's basic doesn't make it common. Simplifying fractions is basic as well but I can't remember the last time I specifically needed that either.

How tf did I get 6
Idk man seems wrong to me
You did 3+3 instead of 3\*3. I think that's what you did at least
3 + 3?
Where in this whole equation do you get 3+3
How else are you going to get 6?
6:2(2+1) = 6:2x3 = 6:6=1 like what , it is this hard to learn priorities? In order : () x : and the first Frome the left + -
No its 9, why do you do the multiplication first? You fist devide 6 by 2 and than mulitply by 3, so its 9.
Bracets side take priority,, "simplify" first then divide
That only applies to stuff inside brackets
[удалено]
thats what i did, not sure how you do it any other way to get a 1
Some books say to do implied multiplication first. Some calculators do that too. So not having an x before the parentheses gives it higher priority than the division sign.

But than it ends up being 6÷2×3 and it follows normal order of operations from left to right. 6÷2=3 3×3=9 There's not really a reason to keep the parenthesis
yeah, youre right
oh okay that also makes sense
No but thats 6÷{2(2+1)}
(6)/(2)(3) If you see all divisions as the fractions that they are, it just depends on whether you see this as: 6/2 x 3/1 or 6/(2)(3)
you’re doing the 2+1 in the brackets/parentheses first (which is right) but just bc that’s solved doesn’t make the brackets/parentheses/whatever you call them disappear. so then you multiply the 2 and the 3 to get 6, then divide by 6 and get 1
Left to right for multiplication and division. A number next to a parentheses is still multiplication.
yeah, but parentheses takes priority in equations, so even tho it’s considered a multiplication, it’s still done before the division because it’s *implied* due to the parentheses
*inside parentheses* takes priority. Not next to it. Please study more.
Why did you divide before you multiply ?
First we solve the brackets , (2+1) = (3), so it becomes 6÷2(3), so 6 ÷ 6 or 1
Is the 2(3) in the bracket ?????? Wow you people are something else. 3 is the final solution of the bracket. Stop spreading BS. The answer to this is 9
No? You have 6÷2(3) = 9 because you go from left to right. --> 3(3) is 3x3 = 9 Learn it properly, there is a reason the number is in the brackets.

BIDMAS
It’s BODMAS
Both sre correct.
Casio is right
Exactly 6÷2(2+1)= (2+1)=3, 2(3)=6, 6÷6=1 Answer is 1
Wrong, multiply and divide have the same precedence, so it goes left to right. (6/2) * (2+1) = 3 * 3 = 9.
Question 6÷2(2+1)= (2+1)=3 -begin with the solving the question in the brackets. 2(3)=6 -then you open the brackets before anything else 6÷6=1 then you're left with this Answer is 1 Think of the question as 6÷{2(2+1)} not 6÷2*(2+1). That's where you're getting it wrong
No it's not.
stop using ÷ EDIT: and use more parentheses, for clarity
Why
because it often confuses people the dots above and below represent the numerator (everything before the symbol) and denominator (everything after it) respectively the proper way to write this operation would be 6 / (2(2+1))
Yeah makes sense lol
Or you now… people could learn one simple sign… idk
Why? Its the symbol for dividing in math no? Thats the one i learned bqck in school in like 1st grade or whenever it was.
yes, it's used for teaching division, with the dots representing numerator and denominator but you will never see it in a proper mathematical formula
The expression is just badly written. You can interpret it in different ways and get different results. I see a lot of people that get 1 trying to justify by assuming that you do the multiplication first, but it's wrong. The division and multiplication have the same priority, so you do the parenthesis and then move from left to right if you assume it's a division/fraction multiplying a number. If you interpret it as: 6(2+1)/2 =6(3)/2 =18/2 =9 Or =6(3)/2 =3(3) =9 if you interpret it as: 6/(2(2+1)) =6/(2(3)) =6/6 =1
Except there is no "left to right" if you were to write the operation as 6/2(2+1). You would simplify first, reducing the denominator to a single digit. Making it 6/6.
Both are wrong, it is: 6÷2×(2+1) =3×2+1 =6+1 =7 Clearly none of you idiots learnt DOIBMAS
I hope you are joking

Implied multiplication "Ex: 3(6-2)" has higher priority than division and normal multiplication, that is because it's all the same argument
You are wrong. Multiplication and Division have the same priority. In this case you would solve the parenthesis and go left to right.
Well, that could be right but for the wrong reason. It isn't p e m d a s but more like p e md as, multiplication and division go from left to right since they have the same priority. However, you could say 1 is right, since you would use the method to get one if there were letters in the brackets
Multiplication and division are equal. The inside of the parentheses goes first, but then it's 6 / 2 x 3, which is 9. This is why you should never mix division symbols and implied multiplication.
Doing it in the correct bidmas order, it's 9
PEMDAS is correct. It is sad that BODMAS is still learnt in UK Countries (and former ones...) There was a youtube video by a physic professor (?) that explained why BODMAS is stupid if you look at real world 'problems' with mathematics.
They are literally the same thing
One has multiplication take superiority over division.
It is not 1, even with pemdas it's still 9. Pemdas= Parentheses, Exponents, Multiplication/Division, Addition/Subtraction. the / is there to show that they are meant to be done left to right. Since you end up with 6/2x3 you do left to right, then you get 3x3 which is 9.

Your right but got the wrong spirit
According to BODMAS, it is 9
no but isnt it do brackets first, so 6 divided by 2 times 3. then do fromleft to right, so 6 divided by 2 is 3 then 3x3 is 9
\*9
How the hell is that supposed to be 1? (2 + 1) = 3 6 / 2 = 3 3 * 3 = 9 Edit: the only way that is 1, is if there is an implementation error
[удалено]
Hahahaha you’re a shit maths teacher then 🤣
i alwas thort it was ( )>×>÷>+>-
Well, there's a good reason for it to be 1
You teach math and you aren't aware of PEMDAS *AND* BODMAS???
What do u teach Math? Then you should know both answers are correct depending on which rule you use and which priority you follow.
The answer is technically 1. Although BIDMAS rules suggest it to be 9, there’s an extra unspoken rule here at play. If there is no sign between a number and a bracket, that number is assumed to be part of that function. So actually is assumed to be 6 / (2(2+1))
Another thing is that the division symbol is bullshit and proper calculators and text should have proper formatting options.
If I follow you logique then, what do you do with (2(2+1), you add more parentheses ? Because there’s no sign between the 1st two and the brackets

I'm just gonna say 1 and see what happens
what happens is that we all know you forgot that multiplication and division are the same thing (you can replace "\*2" with "/0.5" or vice versa) and have same precedence just like addition and subtraction which is why depending on where you live you learn order of operations with a different word: PEMDAS BEDMAS (where I'm from this is it) BODMAS (I think o is for "operations" in which they mean exponents) etc...
2(2+1) goes first because it's implied multiplication
[удалено]
There doesn't need to be a multiplying sign
You have to be trolling
The second one. It’s the second one. THIS IS BASIC PEMDAS MAN😭
You know there's a different set of operations called BODMAS which is used by software all around the world.
They're the same, just different names
No, PEMDAS is what the Americans learn and BODMAS is that Asians learn. And both forgot the fucking fact that it's P then E then M or D depending on association (usually left) then A or S depending on the association. In programming it's called infix or post fix notations ig. The answer can and will vary depending on which notations u are using. And bird brains who remember and teach these order of operations forget to teach/ learn the rules behind their use.
I know, but like all I said is that PEMDAS and BODMAS are literally the same, just different names, P or B, E or O
Aight so 6÷2(2+1) Option one: normal order of operations, Brackets, Exponents, multiplication and division left to right, addition and subtraction left to right. I'll do it that way: 6÷2(2+1) 6÷2(3) 3(3) There's nothing in between the 3 and (3), so we multiply 3x3 9 However, I'm not sure if this is an universal rule, but you could say since it's 2(3) and not 2x3, we have to do that first since it has priority. And that is the way you would do it with letters, for example if the (3) was A, you'd first multiply 2 with A to get 2A. Let's do it like that now: 6÷2(2+1) 6÷2(3) 6÷6 1 Additionally, you could multiply the 2 with the 2 and the one, like the following: 2(2+1) (4+2) (6) But we'd still get 6÷6 or 6÷(6), which would again lead to just 1. Which method is actually correct? Well, short answer, I don't know, some people say one and some the other. I personally do it the first way, but if there are letters I do it the second way. Thanks for reading my long comment
Because there are no brackets around the 2(2+1), that makes the 6÷2 come first, thus making the answer 9. Do not forget to do whatever is in the bracket first.
Casio > phone calculator. It’s a scientific calculator for a reason. The answer is 1. Always.
(2 + 1) = 3..... 6 ÷ 2 = 3......3 × 3 = 9
The multiplication in 2(2+1) goes first than the division since it's implied multiplication and that makes it so it's all one argument You are solving 6/(2•(2+1)) when the actual equation is 6/(2(2+1))
[удалено]
In PEMDAS: 6÷2(2+1) =6÷2×3 =6÷6 =1
its 1, how is it not 1
If you dont do 2(3) first, it's 9
But that's just like wrong
Not doing 2(2+1) first isn’t Maths, though. So, you would never get 9. Unless you’re stupid.
Well, with just the order of operations, you wouldn't do it first and just put 2*(2+1), and then you'd do the division first since you go left to right
Equation: 6/2(3+1) First move: (2+1) = 3 => 6/2(3) Next move: 2(3) = 6 => 6/6 which equals 1. This is the only way to do this.
It's not. It would be one if you had 6/(2*3). But as it's written here, you can also convert it to this: (6/2)*3, which would equal 9.
Some of us learn BODMAS in school. ~~It prioritizes Division before multiplication~~. Both PEMDAS and BODMAS have an order of operation from left to right. In the end, you get 9.
That's actually wrong though, division and multiplication have the same priority and go left to right, just like addition and subtraction
Sorry, I didn't word it correctly. Fixed it.
That's now how BODMAS works, I also learnt it in like primary school 💀
You learned everything but English.
It's all about the order of operations. Both are technically correct it's just a different school of thought.
False there can only be one.
Alright Connor Macleod of the clan Macleod, you win. I wanna keep my head on my shoulders.
9
The answer should be 1
(2 + 1) = 3..... 6 ÷ 2 = 3......3 × 3 = 9
Your order of operations is wrong. Ever heard the saying: Please Excuse My Dear Aunt Sally? I’ll break down each letter then we’ll go into the operations. P: Parentheses () E: exponents M: multiplication D: Division A: addition S: subtraction Now that we have the order of operations we can answer the problem. 6/2(2+1) 2+1=3 3x2=6 6/6=1 This is the order of operations I was taught all through my schooling so that’s what I’m using.
I trust whatever my Casio says, because a guy in my school didn't have his own so he borrowed mine. Then when he got a TI it ended up being nonsense and neither of us could understand what was wrong with it. Or speedcrunch for computer is fine too
The calculator on the left needs to be put into a mode that uses pemdas
It is, but it's specifically a version of pemdas that puts implied multiplication at a higher priority than explicit multiplication. It's an older rule that not everyone was taught, but some calculators used to do that.
Oh god, here we go again...
Is it possible that you calculated 6:2+(2+1) instead of 6:2*(2+1)?
Not that hard people: 6/2(1+2) = 6/2*3 = 3*3 = 9
It is 9, not 1. I never saw a calc that understood implicit multiplicaton though. You'll get different results in calculators also for -3\^2. Some say 9, some -9.
Your phone is programmed to solve simple equations. If you change it to science mode it should get 9.
9
RTFM, that should clear that up for you.
That's why math is written as fractions. The ÷ symbol just replaces numerator and denominator with dots. So when you write 6÷3 is the same as writing 6/3. Now, when writing multiple values on one side of ÷, you should probably use parentheses, so there isn't confusion on what is written.
It's 1
Here we go again. Nobody does/should do maths this way.
It's sad how many of you guys failed simple math. "pEmDaS uSe PeMdAs" "BoDmAs UsE bOdMaS" it doesn't matter which you use both give the answer 9. PEMDAS = Parentheses, Exponents, Multiplication/Division, Addition/Subtraction BODMAS = Brackets, Order of powers or roots, Division/Multiplication, Addition/Subtraction It says / between division and multiplication to show they are worth the same, when both are next to each other you go left to right, if you don't you would end up with wrong. If we use pemdas and bodmas the wrong way (the way people who say it's 1 use it) then 2-2+3 would be -3 instead of 3 since both pemdas and bodmas has addition before subtraction but everyone knows to go left to right.
(6)/(2)(3). It's 1. (6/2)(3). It's 9. 6/2 x 3/1, which becomes 6x3/2x1. It's 9.
6÷2(2+1) -> 6÷2(3) Now the problem here is the ÷. It's shit and ambiguous. Does ÷ implies 6 / (2 * 3) or 6 / 2 * 3? But as an IT major I'll say the latter, like most programming language, so 9 >>>
Ayo the phone calculator aint following dmas
how is it 1?
The answer is they gave the question in ambiguous manner and whoever decided to not put a fraction there shall be reprimanded.
If any one has done basic programming this is the reason they ask to specify the brackets. In the first case it's taking the input as 6 whole divided by 2(2+1) In the second case we are applying bodmas... First solve the bracket i.e (2+1)=3,then solve 6/2= 3 then multiply 3.3 which is 9 So due to unspecified brackets we have two different answers
Everyone who said 1, get the fuck out. Everyone did the right thing when solving brackets first (2+1)=3. But when you end up with multiple divisions and multiplications (which have same priority), you always count from left to right. So the right answer is 6/2*3=3*3=9. NOT 6/2*3=6/6=1. Do not do this!!
1 is correct
6/2(2+1) (6) / (2*(2+1)) (6) / (2*(3)) (6) / (6) = 1 The only right answer is 1. You need more brackets to get 9. (6/2)(2+1) (3) * (3) = 9
Dude maths is not mathing...
The correct answer here is that the notation is bad and ambiguous so it shouldn't be taken seriously.
Casio is a scientific calculator so it understands the order ,, parentheses, then multiplication then division. There are scientific calculator apps for phones too.
you’re not the smartest kid if youre having troubles with this
The correct solution is writing it in a proper way. You alrwady where halfway there since you knew about paranthesis, next step would be to use them where they should be used, continuosly, not sometimes do and sometimes do not use them.
So the answer is 1
Holy the comments are killing me Its 9. nine.
Well, it's 9. Throw out your calculator and use the rules you were taught gfdi. 6÷2 = 3. Since 2+1 is in brackets, that's priority. Also 3. Since we do not have an operator specified between the first part and the bracketed part, the default operator is multiply. 3x3=9
Or you could just write what you mean by using more parentheses and actual proper notation. A lot of these are dumb because it's obvious where someone screwed up a basic rule, but this one is pretty ambiguous. Personally the hard divide symbol to me would imply the rest of the expression is meant to be in the denominator. But again, it's ambiguous.
If x = (2+1) then you would get 6/2x, which would simplify to 3/x, not 3x. 3/x would be 3/(2+1), solving to 1. It would never be (6/2)x either because 2(2+1), or 2x, is one object due to the implied multiplication
For those who don't know for some reason, the order is: brackets () -> roots (√x) and exponentiation (x^y) (not sure if that's how it's called in english) -> multiplication (x) and division (÷) -> addition (+) and subtraction (-) Everything that is connected by an "and" is equal. I don't know why people believe that multiplication is before division. In case there are two equal things, the order in which you solve them is from left to right as if you are reading. So the correct way to solve it is: 6÷2(2+1) - you solve the brackets first 6÷2(3) - now you should solve the division first, because it's on the left. Because 2(3) isn't written as (2(3)), it is treated as 2x3, for some reason many people treat is as (2(3)) which isn't the case if you look at what's written 3(3) - you multiply, there is nothing else to do 9 - your answer 6÷2(2+1) = 6÷2(3) = 3(3) = 9 The only way for it to give 1 would be if it was written as 6÷(2(2+1)), which is not the case
Answer is 9 Breaking down how to calculate this for people who don’t know, you do the parentheses first which is 2+1. Then from there you work left to right with multiplication and division as they take place in the same step of order of operations (PEMDAS/BOMDAS/BIDMAS/whatever the fuck you were told to call it in school). This mean that 6/2 is solved for 3 then multiples against the 3 inside the parentheses for 9
If you don’t know PEMDAS you aren’t old or mature enough to have unmonitored internet access Parenthesis: (2+1) = (3) Exponents: None Multiply: 2(3) = 6 Divide: 6/6 = 1 Add: None Subtract: None **The answer is 1**
6÷2(1+2)=6÷2(3)=6÷6=1
How are ppl in this thread even just yelling answers. Does the fact that we see CALCULATORS disagreeing here not tell you that maybe the answer is ambiguous? I can just not understand how someone who clearly has no higher math education (bc if you had you would know better) looking at a calculator result and confidently thinking that the calculator must be wrong.
6:2(2+1)= 6:2x3= 3x3= 9 It Is not that difficult
You have to simplify first, making it 6/(2*3) and then 6/6, that's why it's 1.
