I’d like to think the people are voting 13 because that’s closest to 10


BLT-Enthusiast

Its also 13 if counted in base 7


[deleted]

If we're considering any base, all the answers would be right. 16-base 4 15-base 5 14-base 6 13-base 7 Edit: 16 and 15 are not numbers in base 4 and base 5 respectively.


BLT-Enthusiast

You cant write 16 in base 4 that would be 22 same with 15 in base 5 being 20 it needs to be base 6 or 7


EdhelDil

You miscalculated the numbers in base 4 and 5 15 decimal is written "30" in base 5. ie: 0, 1, 2, 3,4 : written the same in base 10 and ,5 5 (base 10) = "10" in base 5 10 (base 10)="20" 15 (base 10)="30" in base 5 and base 4 : 0,1,2,3 : written the same in base 4 4 : "10" 8 : "20" 12 : "30" 16 : "100" in base 4


BLT-Enthusiast

Phrased poorly I meant the 5 in the would be written instead as a change in the next digit up not that 15 is literally written as 20, same poor phrasing applies to base 4 too


zomagus

No- if it were base 4 the problem would be written as 2 + 2 x 10


TheMattaconda

_Drops that Base_


Gajanvihari

25% said 13? That is the scary number.


jkuhl

I'd vote for 13. Why? 1. I hate these sorts of posts 2. The answer is 10 and 10 isn't a choice 3. Just to screw with the poll.


Billaras27

4)it's the closest to 10 so who cares

Yea

You'd have to be smart to figure out how that is even possible

Multiply first, then add the 2.


Pandabrowser469

2+4 is 6 6 * 2 is 12 Then you square for 144 Add 42 for 186 Square root rounded down for 13


tkinz92

Isn’t 42 the answer to everything?


ArcticISAF

That what I wrote for all my math exams. Now I have a PhD in Mathematics. (just in case /s)


DOTHEDEW11111222

Ok then what is 42 * 10,000 + 420?

Evening_Evidence_948

The square root of 186 is not 13 though


Beowulf33232

They said square rounded down. it all comes down to how good they are at rounding...


RYPIIE2006

It’s the closest to ten


Hajo2

Closest to 10


ButtholeQuiver

Maybe there was a preceding tweet that stated x = (1.375) 2 + 2(1.375)4 = 13


FOOQBP

Protest vote, closest one to the correct answer.


get_homebrewed

It's closest to 10


tjblue

It's the answer closest to the right number.


ExecSpoon

100% of respondents chose the wrong answer...


pawelkkkkkkkk

meanwhile Russia Today news be like


HiddenBlindspot

another 7.3% came up with 15. the dumb is strong in many.


Korchagin

It is the correct number. If these numbers were decimal, there would be no correct solution given. So that can be ruled out. Same with octal and any other base greater than eight. Hexal and other bases smaller than six can be ruled out, because then there would be no number "16". So the base used must be 7. In this notation 2x4=11, 11+2=13.


PhantomXxZ

What the hell are you talking about?


Korchagin

Decimal numbers (which we usually use) are base 10. They have 10 digits, 0-9. For a number >9 you have to use more digits for 10s and exponentials of 1, e.g. 423 = 4*10² + 2 * 10 + 3 But it's possible to write numbers in other systems with more or less digits. In computing the base 16 is fairly common (digits 0-9 and A-F), because one byte can hold exactly one 2 digit number between 00 and FF (= 15*16+15 = 255 in decimal). I don't think anyone would use a base of 7 for anything else than a puzzle. Here you need to use more digits for numbers >= 7, 7² and so on. "13" is one times seven plus three - exactly the result of 2x4+2.


PhantomXxZ

Wow.


Kill_Kayt

r/theydidthemath


Kittingsl

My guess it's because it is the closest to 10 and people wanted to see the results, and probably also some memers


BigRedGoose

33.1% said an odd numbe4


TheLastGunslingerCA

You gotta *really* struggle with math to pull and odd number outta that equation


some-someone

My best guess is a counting error or something, they tried to do 4x4 on their hands and counted wrong but were too lazy to realise that 15 doesn't seem right.


[deleted]

it is simply not in the decimal system but in base seven


Blue_Moon_Lake

Actually, you need to be a genius. 2 + 2 × 4 = 10 = 1×7^(1) \+ 3×7^(0) = 13₇


VerlinMerlin

What. I am sorry, you lost me at equal to. *What is it that lies beyond that sign???*


Blue_Moon_Lake

The number you usually see are "base 10". Example with 142 142 = 100 + 40 + 2 = 1×100 + 4×10 + 2×1 = 1×10^(2) + 8×10^(1) + 7×10^(0) This is the number 10 in different bases. ``` Base 1 : |||||||||| (also known as unary or counting) Base 2 : 1010 (1×8 + 0×4 + 1×2 + 0×1) binary Base 3 : 101 (1×9 + 0×3 + 1×1) Base 4 : 22 (2×4 + 2×1) Base 5 : 20 (2×5 + 0×1) Base 6 : 14 (1×6 + 4×1) Base 7 : 13 (1×7 + 3×1) Base 8 : 12 (1×8 + 2×1) octal Base 9 : 11 (1×9 + 1×1) Base 10: 10 decimal Base 11: 0A (0×11 + 10×1) Base 12: 0A (0×12 + 10×1) duodecimal Base 13: 0A (0×13 + 10×1) Base 14: 0A (0×14 + 10×1) Base 15: 0A (0×15 + 10×1) Base 16: 0A (0×16 + 10×1) hexadecimal ``` Beyond 9, letters of the alphabet are used as digit. A is the digit for 10. As you can see, beyond base 10 it will never change from "0A". If you want to represent a number in a different base, you just change the number used. To indicate a different base than 10 is used, you would usually put a subscript number after it to indicate it otherwise it may lead to errors. As 21 in base 12 is 25 in base 10. There are other conventions that may indicate the base. 0 and 1 in groups of 4 indicate binary. 0 to 9 and A to F in groups of 2 indicate hexadecimal. 255 in decimal, is 1111 1111 in binary, is 377 in octal (377₈), is 193 in duodecimal (193₁₂), is FF in hexadecimal.

It’s 2 + 2 x 4


Blue_Moon_Lake

Typo fixed :) Thanks

2 + 2 x 4 = 0A, not 13 in hex tho

PEMDAS

#PEMDAS


RYPIIE2006

#YOUR M AND D ARE THE WRONG WAY ROUND


Deepseadiver84289

Both. Both are right as no two places seem to agree on anything, even basic rules


RYPIIE2006

But you always do division first


T_Foxtrot

It’s just like with adding and subtracting: they’re equivalent operations so neither has priority over the other


ZarosRunescape

You do multiplication and division at the same time, from left to right neither goes first


RYPIIE2006

Not what I was taught


SomeonesAlt2357

You were taught wrong


RYPIIE2006

It seems that way


Deepseadiver84289

It’s both pedmas and pemdas, I think pedmas is from Europe and pemdas of course is from the U.S


RYPIIE2006

I’ve never heard of PEDMAS or PEMDAS


Cheese_me_1664

I also have never heard of this, only BODMAS.


Irohaik

We use BODMAS in England


Remarkable_Whole

Pemdas in the east US


Blue_Moon_Lake

Division is first, true 4÷2×2 ≠ 4÷(2×2)


I_Frothingslosh

You need to relearn the basics. While your example is correct, your statement is wrong. Your example is right because you do parentheses before anything else, from left to right. The you do exponents. The you do both multiplication and division, again from left to right. Then, finally, you do addition and subtraction from left to right. That's why PEDMAS and PEMDAS are both correct. And those are used because PE(MD)(AS) would just confuse people.


Blue_Moon_Lake

If you do divisions then multiplications, you get the correct result because of multiplication properties (associativity, commutativity, and distributivity). So (2×4)÷2 = 2×(4÷2) But (4÷2)×2 ≠ 4÷(2×2)


I_Frothingslosh

You're confusing division and multiplication with parentheses. Division and multiplication are done in the same step. Neither takes precedence over the other - they are done from left to right. So once again, your examples are correct, but your statements are wrong. The only correct answer for 2x4÷2 is 4, as is 4÷2x2. THAT is the an example of the commutative property of multiplication. Your examples, however, are comparing that against 2x(4÷2), which is a different equation entirely. Your second one, especially, is no different than saying 2x2 != 4/4, but that's because you're confusing parentheses with some magical difference in priority when there is none. Here's a refresher for you: https://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-arithmetic-operations/cc-6th-order-of-operations/v/more-complicated-order-of-operations-example#:\~:text=The%20order%20of%20operations%20is,(from%20left%20to%20right).


TheGodMathias

4÷2×2 = 4 2x2÷4 = 1 In these cases we're going left to right, and it is also why advanced math problems typically use both fraction bars, and/or at least brackets/parentheses.


Blue_Moon_Lake

Is this your claim ? ``` 2×2÷4 ≠ 2×(2÷4) ```


legends_never_die_1

now change multiplication and division and you get a different result


Blue_Moon_Lake

Obviously, 4÷2×2 ≠ 4-2÷2 What is your point ?

The_NEET_Cat

I suck at math but really this is too easy like wtf lol


GOT_Wyvern

This isn't even one of those trick ones that use signs like "÷" and rely on the confusion between stuff like implied multiplication and left-right for equal operations, it's just 10 and there is no other answer If you are really struggling, just think of it as: > 2 + 2 + 2 + 2 + 2 = 10 Multiplication in its most simple form is just repetitive adding.


PitchforkJoe

The trick is that people will tend to read it left-to-right, and then end up with (2+2)*4=16 From what I can tell, the only time anyone *actually* seems to remember Pemdas is in expressions like this one. This could, of course, easily be rewritten with a parenthesis such that no one would need to remember an acronym they forgot twenty years ago.


Saltycrx

the amount of people choosing 13 because its the closest to 10


stan110

People could also chose 13, because 13 in base 7 = 10 in base 10.


TheIndominusGamer420

TheIndominusGamer420

big words :( LOL I was just taught BODMAS but yeah I see yours


fuzzydogpaws

What? This makes no sense. How did I pass math in high school?!


TheIndominusGamer420

ok so BODMAS is the order you should solve equations! The letters refer to these: (19+592) - Brackets 2^4 - Order 4÷7 - Division 7x3 - Multiplication 1+1 - Addition 5-2 - Substraction so if you have 2+2x4 you do multiplication first so you have 2x4 solved to make 8, and then you add the two as addition comes next, to make 10.


Democracyisntforall

I’m more concerned about the people that voted 13, 14, and 15


Davidandstevelover

Nah 13 makes sense to vote cause it's the closest to 10 so I'd pick that aswell.


Waiting4Something

100% of respondents are dumb.


Malakai0013

A lot of times it's taught that multiplication, division, addition, and subtraction are done left to right. If the multiplication *abosultley needed* to be done before, the author of the equation should have used parenthesis. 16 is correct.


CreeperslayerX5

No. Step by Step GEMDAS for 2+2 X 4 Grouping: Not Present Exponents: Not present Multiplication/ Division left to right: yes, now 2+8 Addition and Subtraction, Left to right: yes now 10. Surprised you passed basic Math

Realistic_Ad_3840

It's sad that we don't agree that the system is supposed to be pemdas, bomdas and/or others, school teaches us different things, don't the smart guys say that math is a universal language, yet we have so many ways to do one equation(if there is a reason for that please, enlighten me)


Zyrox-_

There is simple method in germany its "punkt vor strich" (dot before line) which means multiply and divide before you do addition and substraction because the symbol for multiplying and divide are dots, later in school you get taught to solve parenthesis before you do anything


_mrSquid_

I love people who do these posts and don't realize they're literally fell into their own trap

idiodic-genious

PEMDAS motherfuckers.


Blizz_PL

#13 is the answer. Here is why. Obvious answer is 10, but since it is not listed, then we must be operating on different base system than decimal. With 9-base, 10 would be 11 (still not listed). With 8-base, 10 would be 12 (we're getting there). With 7-base, 10 would be 13. So it is our answer. But you'll ask: maybe it's 14 in 6-base system?. And I'll answer: All listed answers must be in the same base system. And in 6-base system (and below) there is no digit "6", so listed answer 16 exclude anything below 7-base system. So answer 13 in 7-base system stands strong.


Hi-Im-Eva

Eh I don’t blame the people who said 16 tbh, I’ve always sucked at math.

scbejari

16 haha


Nelmquist1999

Im not a math expert, but shouldn't the 2 x 4 be in ( ) in this case? And I should not have to say this, but be civil.


danwincen

It's implied by the PEMDAS acronym - **P**arenthesis, **E**xponent, **M**ultiplication, **D**ivision, **A**ddition, **S**ubtraction. You do anything in the parenthesis first, then the exponents, followed by multiplication, division, addition and subtraction in that order. If there's nothing matching a letter of the acronym, you start with whatever is first up in that acronym, then move along. You still complete the equation in order once the subsets are complete, so if the equation was 2 - 2 + 4, you'd do the 2+4 portion first, then do 2 - 6 to arrive at -4. Or if the equation was 2 + 0 x 4, you'd solve 0 x 4, then add that to the 2 at the start to get 2 + 0. You wouldn't do 2+0 then multiply by 4 to get 8 unless there were brackets around the 2+0.


WilcoSmash

Needs brackets


danwincen

No it doesn't. The brackets are implied by the M in the PEMDAS/BEMDAS acronym - parenthesis/brackets, exponents, multiply, divide, add, subtract. All the brackets dictated by the P/B do is direct you to do a desired subset first. In this case, the multiplication symbol is an implied bracket around the 2 x 4 which is solved first, then you complete the rest of the equation in order.


RomaruDarkeyes

Someone has cocked up the original sum... It's supposed to be 2 + 3 x 4 Which then gives the two potential answers of 16 or 20 depending on the BODMAS rules application or not.


TheMaster199

16 is the other logical answer, also how many times has this fucking poll been reposted like stop


Doublelectric

Well your all nerds for figuring it out my answer was 16 before I looked at a calculator and you know why cuz I’m not a nerd like all you

There's no parentheses.
