This is the correct way to solve this problem. The answer is 2. Remember PEMDAS. Algebraic equations should be in solved in the following order: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. The 2 and 12 therefore get multiplied before being divided into 48.

I remember PEMDAS. Apparently you don't. You seem to think that multiplication comes before division.
This is what's horrible about our school systems. They don't teach math well at all. People tend to think that there is a difference between multiplication and division and thus think there has to be an order to it. But if you (not just RottenChester -- but I am using you as an example) understood basic math, you would know that they are the same thing, and thus would realize that they cannot be ordered. And that FACT has nothing to do with the original problem being questioned here. It has to do with your lack of understanding of math.

I understand that in some instances that the multiplication and division functions are interchangeable.
For example:
(24/4*6)
becomes
(6*6)
becomes
36
However in the original asked equation, 48÷2(9+3)
You DO NOT divide the 48 by 2 and then multiply it by 12! The equation to the right of the division sign commands your attention first because of the parenthesis component. Think of it this way, 2(9+3) is basically like writing the number 24, in that it is a whole number and you can't just part out a piece of it.
You are absolutely right however in that our school systems must be in sorry shape if people like you cannot do 8th grade math.
