I took a test last week and I got this problem wrong:

. . .3 + (-5) - |5 - 8| - 3(-4)

I've tried to rework it about a dozen times, and still cant get it! Please somebody help me before I go insane! I tried it on my calculator, and it says that the answer is 7...

3 + (-5) - |5 - 8| - 3(-4)
3+(-5)+3-3(-4)
-2+3-3(-4)
1-3(-4)
-2(-4)=8

It looks like a step was skipped. The first thing to do would probably be to evaluate the "5 - 8" inside the absolute value. Then take the absolute value of the result. Only then apply the "minus" in front.

You might want to review the order of operations: Multiplication (in this case, the three times four) comes before addition.

Looks like you're unaware that the brackets mean to multiply;
3(-4) = -12
