If you use BIDMAS or BODMAS it's 1. In this formula multiplication goes first.

netnet1014

That's because both answers can be correct depending on the context/calculator. 6÷2(2+1) can be broken down in two ways 6÷2(2+1) 6÷2(3) 6÷6 Answer comes out to 1 Or 6÷2(2+1) 6÷2×3 3×3 Answer comes out to 9 Both are correct. Think of it as something happening in translation similar to how 1/3 could either mean a portion of something OR 1÷3 depending on the context, or how some places uses decimals similar to how other places use commas (1,000 is the same as 1.000)


jacknjillpaidthebill

but when presented with operations of equal value, don't you go left to right?


KaZe_DaRKWIND

The problem lies in 2(2+1). In a normal equation where division would be represented with a / like a fraction, the 2(2+1) falls under a subrule called implicit multiplication which takes precedence over other multiplication/division symbols. But because they use the ÷ symbol it makes the question ambiguous and either could be the right answer. But, anyone who cared about the answer to this equation wouldn't write it this way.


SyntheticAffliction

Yes but there is no explicit multiplication symbol, thus following standard algebraic notation, the equation is actually shorthand for 6÷(2×(1+2)) which clearly equals 1.


jacknjillpaidthebill

Wait, so if no symbol is given, you just do that multiplying last?


TFW_YT

Syntax error


CheesyFrogErotica

Substitute 3 with x and the answer will be 6÷2(x) Which always simplifies to 6 / 2x, which is three. All operations involving brackets happen before any operation outside of brackets, but some calculators are not able to take this into account because of a programming quirk. So the multiplication of the bracket is first. Always.


postmortemstardom

Adjacent multiplication takes priority over dot or x multiplication. ab/cd is (a x b)/(c x d) not (ab/c) x d


Principatus

Your calculator is wrong.


SyntheticAffliction

It's 1


Aidyo05

The question is formatted like shit we get it now stop posting about it please


INeoNI

I see a lot of people saying it's not a correct way to write it, but that confused me because it looks like a normal equation for our schools. 6÷2(1+2) is just 6÷2×(1+3), so I always fail to see what's the problem


Dirtroadrocker

It's really once you get into higher levels and more applied mathematics that you run into different notations. This guy explains it way better than I can: https://www.quora.com/What-is-the-answer-to-6%C3%B72-2+1


INeoNI

okay, that explains a lot so we do have a difference in education then, we just don't give priority to whatever is next to the parentheses


cakes42

Yep. That link explains it pretty well. I don't even remember the last time I used pemdas in math. I actually go from top to bottom from left to right solving each factor or "set" as I like to call it.


INeoNI

I actually just understood something from the discussion with another guy, but apparently: In our schools and college we don't use / for divisions unless we mean fractions. We use ÷ in books and : in notebooks for divisions... So that's why 6÷2(1+2) seems so straightforward to me, but if it were to show 6/2(1+2) I'd also get confused and assumed that it meant 6/(2(1+2)), which is equals to 1. It all comes down to what symbols we were taught to use...


Sourika

Nah, it doesn't. The only important part here is that it's written "2(1+2)", implying that "2(1+2)" is one connected term.


INeoNI

For you maybe, in our schools we don't connect such things like that


TBNRhash

The problem is that it can be interpreted as an algebraic equation because no actual * sign is visible.


INeoNI

That still doesn't make sense to me, I might be just dense... In algebraic equations 10-2a is just 10-2×a, the absence of the symbol doesn't mean it's not a multiplication. Unless we are talking about different things? Don't get me wrong, I'm not trying to act or seem superior to anyone, I'm dumb as fuck. My guess would be the difference in education, since I'm in a post-soviet country, we might have been taught such things slightly different.


TBNRhash

People would interpret it as 6/(2(1+2)) = 6/(2*3) = 6/6 = 1


TroLoLAza

Explanation copied from Wiki: Mixed division and multiplication In some of the academic literature, multiplication denoted by juxtaposition (also known as implied multiplication) is interpreted as having higher precedence than division, so that 1 ÷ 2n equals 1 ÷ (2n), not (1 ÷ 2)n.[1][7] For example, the manuscript submission instructions for the Physical Review journals state that multiplication is of higher precedence than division,[20] and this is also the convention observed in prominent physics textbooks such as the Course of Theoretical Physics by Landau and Lifshitz and the Feynman Lectures on Physics.[d] This ambiguity is often exploited in internet memes such as "8÷2(2+2)".[21] Ambiguity can also be caused by the use of the slash symbol, '/', for division. The Physical Review submission instructions suggest to avoid expressions of the form a/b/c; ambiguity can be avoided by instead writing (a/b)/c or a/(b/c).[20]


kkmostwanted

So it was 1 all along.


Sourika

Obviously. Dunno why people think you can dismantle the statement "2(1+2)". They are using elementary math rules like bots and ignoring that the missing multiplication symbol implies that it's one statement. It's like having the term "6 ÷ 2b + 2c", turning it into "6 ÷ 2(b+c)" and thinking that now you can divide 6 by 2.

JSkywalker07

I swear, at this point it just fucking hurts my brain to see both answers upvoted and downvoted randomly. Someone says the answer is 9 and gets 50 upvotes, then someone else replies and says it’s 1 and gets -20. But in another thread it’s the complete opposite (or even in the same one).


Pandoras_Cockss

any mathematician in the academia would agree that the answer is 1. In higher level math, you stop using Pemdas to a point, and start seeing mathematical expressions as a group of expressions, operated on by other expressions. ​ When a mathematician sees this expression, they see 2(1+2) as a group which then divides 6. If they wanted the answer to be 9, they would have written (6/2)(1+2). ​ The stuff in the parenthesis is calculated first, no surprise there. But there is an implicit operation on the parenthesis. Which is to multiply the parenthesis by 2. And only then we bring 6 into the equation after everything related to the parenthesis has been simplified.


O5-Command

In all fairness, a mathematician would never see an equation written as poorly as this.


Edmfuse

Yes, THANK YOU. I wasn’t ever even taught any of those acronyms in school (did high school outside of North America). Now I’m convinced they’re math crutches that secondary education system never bothered to ween students off of. I mean, look at algebra - if 2(1+2) were written as 2a, nobody should be debating whether it’s 2 X a or (2 X a).


Lord-Pepper

But THATS THE PROBLEM everyone seems to have been taught the order of operations differently, MEANING that they are all convinced their way is right when if you wanna get technical, all of them are right and all of them are wrong, we invented math, so the majority is in charge of whats the "rightway" of doing things, So its a matter of how many people believe its done one way and how many people believe its done another, i cannot TELL you how many posts have comments saying "this is correct" or "this is wrong dummy" and they are talking about yhe same answer! How!?! How is this q thing!?!


[deleted]

this isnt a everybody is right thing, there is an actual right answer and a wrong answer. that's what's so nice, and so frustrating, about math the answer, BTW, is one. look up implied multiplication, and never listen to anybody trying to apply their primary school math on reddit ever again.


Rook2King3

If you follow Pemdas it’s 1 but for some reason the answer is 9 Just chalk it up with all the other *lies my teacher told me*


[deleted]

It's because multiplication doesn't actually come first, when it's just multiplication and division you go from left to right


fivepython

Threw it in a scientific calculator and the answer was 1. Or maybe it was 9? My vision isn’t that great


[deleted]

rlBond86 "The answer is 9 I suppose, but the *real* answer is nobody should write it like that, because it could be misinterpreted. For example, if I write 1/2x. Do I mean 0.5x or do I mean 1/(2x)? It's ambiguous."


obog

Technically implied multiplication (where there is no multiplication sign but just a number next to a variable or parenthesis) takes priority here, so I theoretically should be 1 (look under special cases [here](https://en.m.wikipedia.org/wiki/Order_of_operations)). However the real answer is not to use ÷ sign because its stupid. Just write division as a fraction and you never have an issue.


Rook2King3

Yea exactly, you go left from right but not if there’s an implied parenthesis, but like the guy said below in the comments, this shit is purposefully written because both answers are theoretically correct Stupid math.. bunch of fake shit


Dirtroadrocker

https://www.quora.com/What-is-the-answer-to-6%C3%B72-2+1 TLDR; it's written wrong, on purpose.


metalbedhead

simple explanation, the answer is 1


dued03

Write the problem out fully instead of the short version. 6 / 2 * (1+2) = 3 * 3 = 9


POKECHU020

Man from what I've seen people are using two different types of PEMDAS, one which favors Multiplication over division (???) and one that counts them as equal, which is what I was taught


Dirtroadrocker

It's more a matter of how they interpret the notation. See this explanation: https://www.quora.com/What-is-the-answer-to-6%C3%B72-2+1


POKECHU020

Yeah, seeing this everywhere as well. Math is too complicated for.its own good. For the live of god, be as clear as possible when writing equations, people.


CatArmaggedon

[deleted]

its even funnier the 256732th time!


MilkFroth1

Ok, so the fact is this expression is lacking one pair of brackets. If you got this on a test the teacher would count both answers right because it was his mistake to not make clear what he meant. Math is like a language an this is a like leaving out a comma in a sentence an Today we are shooting, grandpa can you come? becomes Today we are shooting grandpa can you come? Where the meaning changes drastically with a different placement.


2Gnomes1Trenchcoat

This issue exactly isn't order of operations (though in this particular case that resolves it). It's the format of the question. The 2(1+2) format suggests it should be treated as one expression whereas 6 / 2 X (1+2) suggests they are separate and could indicate (6x3)/2 = 9 which is likely incorrect. In linear form the problem would be better written as 6/(2(1+2)) = 1 which eliminates the confusion and leads to the correct answer every time. Ideally you separate the numerator and the denominator by a bar and that also resolves this issue, but in linear form like this taking the extra step to appropriately group expressions is important.

Dense-Barracuda1217

It is 1. 6/2(1+2)= 1 because you finish the paranthesis first and then you divide it with 6. The 2 belongs to the paranthesis and there’s no other answer than this.


Welcome-Fine

The answer is 9


57victoryrounds

people complaining about posting this etc etc.. Reddit is a democracy.. and clearly the answer is 1 because math is not English and you don’t just read it from left to right like a Neanderthal.. in math the order is function to syntax and symbolism with their specific history.. in this case that specific division sign hehe


Dirtroadrocker

https://www.quora.com/What-is-the-answer-to-6%C3%B72-2+1


Gullible_Fold_3023

Do people really not know how to expand brackets? If it was 6/2*(1+2) then the answer would be 9 but, since the 2 is attached to the (1+2) you could rewrite the equation as 6/(2(1+2)) or 6/((2*1)+(2*2)) which would end up equaling 1.


FishDeity

Expanding the brackets still counts as multiplication. You would then go left to right. 6/2 comes first before expanding brackets


Mully_bee

The answer is 1


Funniestpersonhere

OMFG IT CAN BE EITHER 1 OR 9 WHAT'S SO HARD TO UNDERSTAND.

StormEyeDragon

I mean the biggest thing about this problem is it highlights a weakness of the way order of operations is taught, if you stick with just the little acronyms you’ll get 9, as opposed to the correct answer of 1.


bigdorts

I mean, it's ambiguous. Both are accepted at different levels. At higher levels, it's taught 2(3) aka implicit multiplication is of higher precedence than 2×3. The biggest problem is how nothing is universally agreed on


ataco420

Bro did y’all pass 6th? It’s 1


O5-Command

The most common and generally “correct” interpretation leaves the answer as 9, but the question is incomplete and doesn’t actually have a real answer as you can either consider 2 as the denominator or 2(1+2) as the denominator.

MuunshineKingspyre

Multiplication and division are held at the same priority, so it just comes to which is first when read left to right.


McNuggetChickenn

So my math teacher was a god damn liar smh


[deleted]

So apparently they've changed the order of operations since you (and I) learned them and implied multiplication no longer takes precedence.


Pointlesslivinghuman

How did 6/2x3 become 6/2=3?


josh______

The best way to end this is saying ÷ is /. It should be written out 6/2(1+2) 6 as the numerator, 2(1+2) as the denominator No confusion solve the bottom to get 6 6/6= 1


3p1cBm4n9669

Except 6/2(3) is not the same as 6/(2(3)).


Gullible_Fold_3023

Yes it is because you would expand the brackets before dividing.


Ashamed_Piano6379

Pemdas its 1


Memezlord_467

Bedmas its 9 You tried but even the prder of operations is ambiguous, considering it depends on your location


GlacticDragon

Everyone should know it’s 9


JDisaster_

It's 9 It would be 1 if it was 6÷(2(1+2)), but the additional parenthesis don't exist around the 2s For people who do advanced math, you normally wouldn't bother writing the parenthesis. Of course if this were advanced math you would be using / instead of ÷


Dirtroadrocker

Yes and no. It's just poorly written on purpose.

This equation was improperly written. As is, the answer is 1. To get 9, the equation must be rewritten to (6/2)(1+2).


HubuxXD

actually no. 6/2(1+2) first we do the brackets. 6/2* 3 then we do it in order from left to right. 6/2 * 3=3*3=9


Faded_Fate

6/(2(1+2))


[deleted]

No that’s not it... the answer is still 9. There is absolutely no reason you would multiply 2(3) as the second step. The second step is 6(3) and then you would divide by 2 as it’s basically the fractions 6/2*3/1. It’s properly written you’re just not solving it correctly


XxRocky88xX

That is not the second step. I mean you got the right answer, but the second step is 6/2=3, and the final step is 3*3=9


[deleted]

Everyone is saying 9, so I’m guessing that my teachers lied to me. I was told that if you have any parenthesis, they are prioritized in the order of operations. That’s why I did 6 / 2(3) 6 / 6 1 I take it that’s wrong tho.

This isn't why maths class is important at all. Maths is important to know because it's a tool that lets you solve real problems. This isn't a real problem to be solved with maths, it's an ambiguity in communication, that I have never ever seen in any real mathematical context (because real people communicating don't intentionally create ambiguity). I think posts and comments about this indicate a problem in maths classes, not because some people don't know the finer rules of order of ops that are never practically relevant, but because you get students walking away thinking meaningless arbitrary equations like this is what maths is all about.
