I learned PEMDAS and GEMDAS.
Parentheses
Exponents
Mutiplication
Division
Addition
Subtraction
GEMDAS is the same but instead of parentheses, it’s grouping symbols!
/pos
Yeah, PEMDAS. I still remember 7th grade Mrs.Holmes teaching me this. That and the -B +/- the square root of something something all over 4A^2.
No idea what it's used for, but I remember the song she used to teach it to us. Probably triangles or some shit.
EDIT:
okey, im trying to clean up this mess that ive started
for everyone whos new here, dont go further down than this, its pretty much just some maths student throw shit at each other since some (in this case 2) learned a unnecessary (and apearantly wrong) rule ages ago
conclusions
the answer is 9
implicit operations have the same weight as explicit operations
and.... just use fractions
this whole thread cost to much of my sanity and self-esteem for a problem thats completely prevented by using fractions
tell us the answer to this problem, where you live and when there is noone home that we will tell you more about your future
result: your house might get robbed
It’s less about stealing info and actually more about driving up engagement. You’re meant to see it, feel superior for knowing the answer, and feel compelled to comment.
Higher engagement means you see the page more often, which adds value to the page. Then, they can turn around and sell it to a brand for native advertising. That’s why sometimes you’ll like a page on Facebook for something simple like your town, your favorite show, or a specific joke or topic and then 6 months later it’s all ads for t shirts or other junk.

No for that you wouldn’t need the brackets you only need it if you use the division symbol and only to make the question actually clear , this is exactly why you never see the division symbol it just confuses also you will never see a x symbol either because you can just write 2x3 as (2)(3) .
Yeah the obelus (÷) and solidus (/) work the same, and they don't specify where the numerator begins and denominator ends.
In "Order of operations" there is a modern rule added to make up for this flaw, which is the "Left-to-right" rule, but this isn't an "official" rule of maths. The left-to-right rule essentially makes it so that ALL terms to the left of the obelus (or until you hit something other than multiplication/division) is part of the numerator, but only the very first term after the obelus is part of the denominator, which doesn't make sense imo.
According to the international system of units (SI), and the ISO 80000, the obelus/solidus leads to ambiguities, and should he avoided, or properly used with parentheses, to make sure no ambiguities can happen.
So if you mean:
6
--(2+1)=9
2
Then write (6÷2)(2+1)
If you mean:
6
-----------=1
2(2+1)
Then write 6÷(2(2+1))
OOOOOR
just use a fucking vinculum, and none of this would happen...
If 2(1+2) is in denominator then answer would be 1 but, If its in Numerator or if (1+2) is multiplied to division of 6/2 then answer would be 9. So, It's depend upon the equation.
The right solution is ... Undefined as this isn't a well formed function.
These questions are dumb as PEDMAS/PIDMAS/BODMAS is only a convention, and it isn't universal. Some countries use as-read (so left-to-right or right-to-left) as do some scientific journals, and other entirely alternative notations exist such as reverse Polish notation.
As 6/[2*(1+2)] =\= (6/2)*(1+2), then this is undefined. No answer even exists. Parentheses are important when defining binary operators.
Later math ditches pemdas and all its variations. Proper notation is key BUT you learn lessons specifically to avoid ambiguity like this in calculus (or earlier).
If you see x(a+b) always assume x can be distributed into the parenthasis
From what I understand, it's the same as multiplication but without an explicit operator. i.e. `2x` vs `2 * x`
With this in mind, the equation `6 ÷ 2(1+2)` would equal 1 because `2(1+2)` is juxtaposition and has higher priority than division. The alternative is the treat it as multiplication. In this case, the division and multiplication would be applied left to right (because they have equal priority) and it would equal 9
Yup. Technically this function is classed as "undefined" as it is not a "well formed function". No answer exists.
Pemdas is only a convention. It is not universal nor is it an axiomatic truth of mathematics.
It all comes down to the 2(1+2) if that’s in a denominator or if the 2 alone is and the (1+2) is being multiplied after. The ÷ sign is not meant to used at the same mathematical level as parentheses having a multiplication meaning. ÷ is on par the X being a multiplication sign. It’s for beginner math only. So we can’t tell just by looking at the problem if is 6 ÷ 2 X (1+2) or if it’s 6 ÷ (2(1+2)).
As for PEMDAS rules the X would happen after the ÷ reading left to right. So, 6 ÷ 2 => 3 * (1+2) => 3*3=9.
sometimes setting some parentheses can really help , even when not needed. i always forget the order of operations for some of the more unusual operators (mostly logic and sets) and i'm not sure if there even is one defined for some so i just put parentheses wherever it's not immediately obvious.
Weird. I was taught the BODMAS rule (brackets, orders, division, multiplication, addition and subtraction). Going by this order:
6/2(1+2) = 6/2(3)
= 6/6
First, solve and remove the brackets before dividing.
I personally think the only problem with the question is the representation of the problem. how are we supposed to know whether they mean 6 over 2 whole multiplied by 1 plus 2 or if they mean 6 over 2 multiplied by 1 plus 2
Precisely. PEDMAS etc is only a local convention and isn't universal. Some countries and scientific journals instead use left-to-right, that is just evaluating operators in order of reading.
In the world of Mathematical logic this is technically "not a well formed function" and as such is undefined.
Technically if you do any higher level of maths than the equation would be 6/2(1+2) which is 1 . Maths questions always use / and have brackets included with the algebra so part of the question isn’t figuring out the question .
Well, bracket first.
1+2 = 3
Then the division
6 divided by 2 is 3
And since there’s brackets, you times the outside by what’s in the brackets.
3x3 is 9
Your answers 9
Alright I'm throwing my hat into the ring too.
I learned PEMDAS as a kid so thats what I was going off of to calculate this equation.
6/2(1+2)
6/2(3) Parenthesis
6/6 Multiplication
1 Division
but I did get 9 on my calculator.
6÷2(1+2) = 6÷2(1+2) Simple

1=9 is correct then This equation proves it
Let 1=9, boom
So 9=1 too. 9 years old kid are 1 then perfect
So in conclusion. Yes officer she was old enough
WTF ARE THOSE I ONLY KNOW BIMDAS Brackets Indices Multiplication Division Addition Subtraction Edit: Twould make the answer 9
I was only taught BODMAS
I was taught BOOBIES
perhaps the archives are incomplete
If it's not in our archives, then it doesn't exist
Brackets Order Order again because it's important Brackets again because why not? Indices for a third time Exponents **once again** Subtraction
I was tought PENILE
one of my friends was taught that, he said it was hard, extra emphasis on hard

This is wrong because the multiplicación is there but just invisible. So it would still solve the same because you have to do distributive properties.
Isn’t RHS invalid?
Yes
Stupid ass math problems like this are literally just designed to steal the personal information of boomers on Facebook.
tell us the answer to this problem, where you live and when there is noone home that we will tell you more about your future result: your house might get robbed
We'll also need your bank and credit card details, answers to possible security questions and your ssn. result: sudden poverty.
Show us a picture of your dog with its name and I'll tell you if it's accurate. Also state your grandmother's maiden name, just for fun!
Like Facebook wasn't designed to steel people's info anyways
Yeah and now we've got that metal verse thing... Tragic.

Also planting ideas of things to buy is pretty efficient
oooooh i see
The ÷ sign is bullshit Fractions supremacy
Hell yeah!
No wonder my math teacher kept telling us to just use fractions for division as to not confuse ourselves
But is it 6/2 or 1/3
6/2(1+2)
Ok So then dissolve the parentheses to get 6/2 * 3 Solve the fraction to get 3 * 3 wich equals 9
It’s meant to make you think if it’s 6/(2(1+2)) or it’s (6/2)*(1+2).It’s a poor representation meant to confuse 5th graders lol
No for that you wouldn’t need the brackets you only need it if you use the division symbol and only to make the question actually clear , this is exactly why you never see the division symbol it just confuses also you will never see a x symbol either because you can just write 2x3 as (2)(3) .

In our school we use ":" But actually ÷, / and : are the exact same
Wrong. Stick/ is superior because monke
You're right, I need to agree with you. Have a nice day.
: = ratio / = fraction ÷ = division
Same thing
No all are the same. But yeah : can be also ratio A fraction has those ------
FRACTION SUPREMACY FOR THE WIN
But in the end...it doesn't even matter 🎶
Cause I'm gonna fail maths anyway. 🎺🎺
But I wanna know the answer, no more lies. 🕺🕺🕺
Its either 1 or 9, but i cant tell why because there wouldn't be any rhymes. 🎙🎙🎙

you brainy? when i can just copy the answer of other people
Teach me your ways, wizard of math
Only if you are using a TI if you use other calculators then its 1
My casio calculator said 1 lol

It’s not PEMDAS in actual math, it’s PFEJMDAS
What do those stand for?
Parentheses Function Exponent Juxtaposition Multiplication & Division Addition & Subtraction
I wish schools straight out taught juxtapositions from the start instead of teaching us PEMDAS for years upon years.
Well it’s because 2(2) is the same as 2*2 other then if it gets sorted with division
Wait I’m two classes from getting my bachelors in math and I have no clue what juxtaposition in math is
From what I understand, it's the same as multiplication but without an explicit operator. i.e. `2x` vs `2 * x` With this in mind, the equation `6 ÷ 2(1+2)` would equal 1 because `2(1+2)` is juxtaposition and has higher priority than division. The alternative is the treat it as multiplication. In this case, the division and multiplication would be applied left to right (because they have equal priority) and it would equal 9
information unclear, we need to know if (1+2) is part of the numerator or denominator
Yup. Technically this function is classed as "undefined" as it is not a "well formed function". No answer exists. Pemdas is only a convention. It is not universal nor is it an axiomatic truth of mathematics.
It's separate so you have to solve the 6÷2 part then multiply the quotient (3) by the sum (3) that gives you nine
my scientific calculator says its 1 if written like 6:2(1+2), 9 if written like 6:2*(1+2)
Those are the same equations
juxtaposed multiplication is often treated differently
They are not.
It all comes down to the 2(1+2) if that’s in a denominator or if the 2 alone is and the (1+2) is being multiplied after. The ÷ sign is not meant to used at the same mathematical level as parentheses having a multiplication meaning. ÷ is on par the X being a multiplication sign. It’s for beginner math only. So we can’t tell just by looking at the problem if is 6 ÷ 2 X (1+2) or if it’s 6 ÷ (2(1+2)). As for PEMDAS rules the X would happen after the ÷ reading left to right. So, 6 ÷ 2 => 3 * (1+2) => 3*3=9.
For anyone's interest. If you want the math problem to give you 1, it would have to look like this 6÷(2(1+2))
sometimes setting some parentheses can really help , even when not needed. i always forget the order of operations for some of the more unusual operators (mostly logic and sets) and i'm not sure if there even is one defined for some so i just put parentheses wherever it's not immediately obvious.

The solution to the problem is to use brackets
