Well I am 27 years old, and I was tought in pre-algebra that when parenthesis is used as both a determining factor and a multiplication line you leave your answer in the parentheses and still apply determining factors which say parenthesis first everything else after. My husband agrees and he is working on his BA in Computer Information Systems and he uses these rules when he does his math. So I am going to believe him since it is getting him an A in math and other classes that use math.
