Simplify (-63) + (-7).
a. 8
b. -8
c. -70
d. 70

Answer 1

To simplify (-63) + (-7), we combine the negatives by adding the absolute values and keeping the negative sign to get -70. The correct answer is (c) -70.

Step-by-step explanation:

To simplify (-63) + (-7), you simply combine the two negative numbers by adding their absolute values and keeping the negative sign, as they are both negative. The sum is indeed a negative number since you are essentially adding up how much 'debt' you have if you think of negatives as debts.

So, the simplified form of the expression is:

-63 + (-7) = -63 - 7 = -70.

The correct answer is therefore (c) -70.
