Answer
5-n
Step-by-step explanation:
If you multiply -8 and -9 it's 72 because If you multiply two negatives it turns into a positive number/answer and if you add -8 and -9 it's -17.
-8 + -9 = -17
and
-8 * -9 = 72
Oh man, this is the easiest college level math question that I could find as a middle schooler. I would say 8, but it's probably the wrong answer, so um bye.
