Answer 1

-50

Explanation:

(-5)(+2)(+5)

(-10)(+5)

-50

A short cut when you are multiplying integers is to count the negative signs. If the total number of negative signs is even, your answer is positive. If the total number of negative signs is odd, your answer is negative.

In this situation, we have a total of 1 negative sign. That is an odd number so our answer is negative.
