Question

Pls help !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

it’s just -9 since 2 + 7 is 9, but they’re opposite signs so it’ll be (-2) + (-7) = -9. The signs don’t change since both numbers are negative

Answer 2

The answer is 14 because -2 x -7 = 14. If you didn’t already know a sum is the value given when two or more numbers are multiplied together and the reason -2 and -7 multiply to get 14 is because the negatives cancel each other out to create a positive.
