That still leaves the question of whether to follow the convention of parenthetical multiplication first or not. That rule may or may not be fading due to increased usage of calculators and computers. Transforming the problem changes the fraction.
As I've stated numerous times, the original problem that sparked the controversy would likely have had a fully written out fraction that would have made the whole thing very clear.

EDIT: I think you're trying to distribute across division. Take a look at the distributive rule. 1(1/2) is not the same thing as 2(9+3). And if you're going to continue arguing about distribution, READ THE THREAD. PARTICULARLY THIS BIT HEURR
Then if you still don't get it read the next two pages of this thread.
Then if you still don't get it read the next two pages of this thread.
Ok 1(1/2) = 1(.5) = .5 = 1/2
And 2(9+3) = 18+6 OR 2(12) = 24
I don't get what you think I'm doing wrong. I already told you the logic I used on the 4/(1/2) was crap. It's the same logic people are using to justify 288.

It's clear as it is. You people just can't seem to follow a simple syntax...

That has nothing to do with the problem we're talking aobut and everything to do with why multiplication and division are weighted differently.

If it were written:
48÷(2(9+3))
48÷(2(12))
48÷(2*12)
48÷24
=2
But it's not written like that which is what people don't seem to get.
Wow, this is still going?
As far as the problem I've got to say I was wrong or better yet only half right. It can be 2 If the denominator of 48 is 2x(9+3) or it can be 288 is the denominator of 48 is only 2. So in all honesty the only ones wrong are those saying there is one answer also if you say it is 2 because you think pemdas says to multiply first. I'm sorry you have the one of the right answers but for the wrong reason. You got lucky but thats it.

There is only 1 answer. It's the retards that can't follow proper syntax that can't get it.

GG hoss. you're *** blocking just like the dude above you was.
Think about this in the larger perspective and you'll see why the problem arose in the first place. Which is frankly the more interesting question to begin with.
Dividing by 2 is the same as multiplying by 1/2 which is .5
A number next to parenthesis means multiply.
It's not that hard.
48÷2(9+3)
becomes:
48*.5*(9+3)
48*.5*12
=288
How much easier could it be?

I thought that at first to if you read my posts prior to that one I went on a rant about people not knowing how to use Pemdas.
The thing is if the problem is like this.
It's 2.
but if it's like this
it's 288.
The problem with this problem is that the notation is absolute ***lol. No one in higher math would use this symbol. ÷

Then your problem is that you're relying on your calculator to much. I'm sorry to tell you, but it's true. If your calculator came up with the wrong answer, then you used it wrong or you read the question wrong.

I'm not going back through why its the case again. Think about how a faction is resolved on one line in a calculator. If you can understand the difficulty in displaying a faction on one line, you can see why a person entering this into a calculator can get it wrong. If you want a simple answer to the problem then there you go, you have it. If you want to know how to avoid making mistakes in the furture, then think about its broader implications. You know what you're looking for when you enter a calculation in a calculator. The calculator doesn't.
I don't know what else to tell you brospeh.

You either think 48÷2(9+3) means:
A) 48÷(2(9+3)) OR;
B) (48÷2)(9+3)
I get it, it means A.
That why no one above 4th grade uses ÷
It should have been written as a fraction 48 / 2(9+3) flipped vertical

______ = 2
2(9+3)

FACT: MOST CALCULATORS ARE TOO STUPID TO KNOW HOW TO COMPUTE THE ORDER OF OPERATIONS.
I figured that out in 2nd grade.

There is no error. Neither answer is wrong given the ambiguous syntax.

You'd hope graphing calculators would be able to, ti-85 and ti-86 are both graphing calculators.
You were right! No WAIT! I was Right!

No because that would of been 48(9+3)÷2...
Now your just arguing just to argue. Swap out ÷ for / which is the same exact thing and you now have a clear numerator and denominator.
48÷2(9+3) = 48/2(9+3)
Numerator 48 / Denominator 2(9+3)
