The answer is 288, but it has nothing to do with going left to right like some of you have said.
M/D and A/S are equal operations, than can be done before or after. The only rule is 9+3, first.
so its 48 x 1/2 x 12 or 48 x 12 x 1/2
While your answer is true, left to right matters when division or subtraction is involved. For example in this problem, if you did 48/2, then times (9+3) you would get 288, but if you did 2*(9+3) and then 48/24 you would get 2. Thus, going from left to right matters when dealing with operations that are not commutative.
No, this is not correct. You can division or multiplication first, whichever you like. They are the same.
If you multiplied 12 x 1/2, before you multiplied 48 x 1/2 it makes no difference!
The only question is here is, does the equation read to divide by 2 or multiply by 2.
