no its 2, type it into any graphing calculator and its 2. The only way to get 288 is if you perform the division and multiplication BEFORE parenthesis. You are not allowed to do that. Parenthesis are always first

That's what I was taught as well so I made it 2 (but then it was a long time ago...).
EDIT: I've changed my mind. Writing it down properly as 48/2*(9+3) I can see it's 288. You still do the parethesis first but then it's 48/2 multiplied by 12.

So, let me get this straight....we're doing algebra, on a Friday. Hell no, my schooling days on any Friday ended in HS. lol But I answered 288. I was taught PEMDAS, with multiplication/division and addition/subtraction being of equal weight in any mathematical equation. Left to right was how we were taught to deal with these sort of things. Very cool brain teaser, if you will, to start the day.

We can all agree that the parentheses are solved first, which leaves:

482(12) which equals 482x12

Those claiming "left to right" are correct in that the answer is 288.

In reality, and not third-grade order of operations, the 2 has two equal potential actions and it should have a parentheses around the intended next function. Digitization has rendered the traditional "left to right" somewhat irrelevant, and orders need to be expressed explicitly.

I get the feeling the OP is an accountant at GM...

"is our profit 2 or 288? I'll ask on the forum...."

HAHA

How I picture it:

48/ 2(9+3)

which becomes...

48/ 2(12)

24(12)

288

The way I'm seeing it is that the 9+3 is NOT underneath the division part of the equation. If it were, then the equation wouldn't be 48/2(9+3) but would instead be 48/(2(9+3)). I think this is where many people are getting confused in their operations. Then again I hate math with a passion, took me till middle-school to figure out %'s......

I got 2 as well, remembering back in the old days

and I always "remembered" division as having the least priority

I'm going to be tutoring my kids later on and I better get this straight

In longer syntax I came up with 2 because the division sign appears to isolate 48, but in fraction syntax it is clearly 288. You feel like when it is in the longer syntax that you are doing it out of order, but you are really just doing it wrong period.

The answer is 2
When you get to 48/2*12, why are you doing the multiplication first? Multiplication and division have equal weight. Once you get to this stage, you go left to right, leaving you with 288.

TI89 Titanium says it's 288, u mad? The only way to get 2 is to put in parenthesis that aren't there already. You are not allowed to do that. 48/(2(9+3)) = 2, but 48/2(9+3)=288.

What people are not visualizing that is screwing them up is this:

48 / 2 * (9+3) =

I initially went with 2 because I multiplied after adding 9 and 3 first. But calculation should be from left to right so 288 should be the correct answer.
