48÷2(9+3) = D'awww

I saw this on another forum and a ton of people had different answers. A ton of people were having an arguement about it and I found it very funny so I figured I would bring it here.

500 of 1000 educated people got this answer wrong worldwide.

48÷2(9+3) = ??

Re: 48÷2(9+3) = ??

Its 288. How can a ton of people have different answer about it?

48 divide by 2 is 24.

9+3= 12

24 x 12 = 288

1+1=3

Re: 48÷2(9+3) = ??

Its obvious where the difference comes from. Some do what you did some do the multiplication before the division and get 2

Re: 48÷2(9+3) = ??

Either way it's a poorly written problem

Re: 48÷2(9+3) = ??

It was probably intentional

I think you may want to stop and check the credibility of where ever you got that from, particularly to identify what they consider "educated". Anyway, order of operations, blah blah, pointless thread not funny.

Re: 48÷2(9+3) = ??

so whats your answer? i lean towards 2

Re: 48÷2(9+3) = ??

It's a very poorly annotated equation. Who the hell uses the ÷ symbol for this stuff? The answer is either 288, or 2. I don't know, or care, enough about maths to make a distinction. I doubt anyone here does. Maybe 48 might, but he's not here so whatever.

what symbol would you use for division? this /? doesnt change anything

QFT.

Of course it was, it lacks the appropriate symbols.

Fist of all 2(9+3) is NOT always 2*(9+3). Some people/institutions interpret it as 2^(9+3), which would be a completely different number, so the lack of the indication of operation is faulty.

Also, the presentation is laughable. This is how you represent division (for example):

That ÷ symbol is nonexistent after elementary school classes (at least here). So that's another thing that is incredibly faulty.

Finally, the order of operations depends on the countries: here division has priority over multiplication, but it's different depending on the institution/country, so of course it'll have different results.

So, with might be 2 (if you multiply before division), 288 (if you divide before multiplication) or 3/256 (if you use exponential instead of multiplication).

There, happy?

how is it faulty if thats the sign for division? means the same thing as this /.

really, why would your country teach math different then everywhere else, i thought that math was the universal language everyone spoke the same.

Except nobody (after elementary school or junior high in some cases) uses them like that. Did you see the fraction I posted (although is a little blurry, damn google image betrayed me)? That's how people present division in a way that is clear to everyone.

That's fallacious to think. Mathematic is indeed a universal language, since it uses the same symbols in the same processes. But like any language, some stuff varies from region to region. Some regions give priority to division, others to multiplications, some to addition, others to subtraction. The difference in the final result should be nonexistent if the math problem is presented in an adequate form, which isn't the case here. Which reminds me of another thing this thing lacks: more brackets.

so the sign for division(÷) is unclear and faulty? its not clearly saying divide and the other symbol / does not mean the exact same thing?

i was under the impression that the universal rules were all the same to solve a math equation. you know multiplication and division being equal but i guess your country decided to do math their own way.

Yes, both are the same thing, but I haven't seen ÷ in ages on math problems and / is faulty if the proper annotations are missing.

Let us take for example 2/3*4=?

What does this mean? Is it two thirds times four or two divided by the product of multiplying 3 with 4? Nobody knows, because it lacks brackets.

So it should be either (2/3)*4 or 2/(3*4). See? That's how math works, genius.

Yes, they are, but I think you're not getting what I'm saying.

Let us take another example: (2*3)+(4/5)

Which operation takes priority while solving the problem? Some people go straight to the multiplication, while others prefer to tackle the division first. The result will be the same, but the process of solving it will be different.

Now if you take a piss poor math equation like yours, people that learn to do the multiplication first will do it and get 2, while others, like kluang and myself, would tackle the division first and get 288, and the difference shouldn't happen. Who's fault is it? Not ours, that's for sure.

actually thats not how math works, it would be (2/3)*4

you do what ever is in the parentheses and then add them both. nothing really to think about here.
