i got to the 2nd page on the bodybuilding forum before i couldn't stand how many people were getting it wrong

I was convinced it was 288, but with the parenthesis... well it's been a while since I had to really focus on the order of operations so I was almost convinced it was 2.

My gut says 288. What do you do when in doubt? ASK GOOGLE.

You can enter math problems into the google search box and it will answer it for you.

Google says: 288

Problem solved :P

Here's the trick for those of you who thought 2. Everyone is saying parenthesis go first. Which is right. But even then you get:

48 / 2 * 12

The answer is 288 whether or not you do the parenthesis first. The problem is if you do the parenthesis first, your brain, since it's already on the right side of the problem, starts thinking that it should go from right to left.

48 / 2 * 12

/ and * are equal when it comes to the order they should be done, but a math problem STILL needs to read left to right.

Instead of 48 / 24 it's 24 * 12. It would only be "2" if it was 48 / (2 * 12). Patenthesis are not only used to override + and * preference, but to override left-to-right. And since everything in the parenthesis is done and gives you 12

48 / 2 * 12

There are no more parenthesis left so all operators being equal, go left to right

I think this problem should be explained by a few more people.

New question! (3x-5)(-3x+5).... Watch no one entertain me, everyone will just ignore it.

-9x^2 + 30x - 25

X= can be anything, there is nothing to stop me from saying X=1 which would make your answer (-2)(2) which would be -4. If I use a X=2 theory then your answer would be (1)(-1) = -1 so on and so forth.

dont ask how i got it.

If you solved it as 48/X(9+3) = 48/12X if x=2 then it is 48/ (2)12 which equals 2. The question as it is written is confussing. If you had 48/2*(9+3) it would be 288. But if the denominator is 2(9+3) it is 2, because you would solve the denominator before you divide. So is it 48/2 * (9+3) or 48/(2(9+3))?

...no.

just...no. you solve parentheses first, then exponents, then multiplication or division in order from left to right, then addition or subtraction from left to right.

that's basic math. like, 4th grade math.
