You need to remember PEMDAS

OpenStudy (igreen):

First, let's simplify the bracket. [12 * 6 + (-42) - (-15)]

OpenStudy (igreen):

A positive and a negative equals a negative..so we have: [12 * 6 - 42 - (-15)] Multiply -1 to -15..what do you get?

OpenStudy (anonymous):

-15

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (igreen):
