: Apperently I misunderstood the actual problem, as it was read to me over the phone. The problem should actually read as follows:
Trying to find the answer to:
-6-(-7)--15-(-12)= ?
Cannot remember how to manipulate (-7) and (-12) to work the problem. It has been a while since I've had Algebra and I am trying to help my girlfriend with a problem from a previous assignment.
Sorry for the inconvenience.
