Answer:

-8 - (-3) = -8 + 3 = -5

7 - (-8) = 7 + 8 = 15

The answer for the first one is -5 and the second one is 15.

Remember 2 negatives = a positive

2 positives = a positive

Answer:

Step-by-step explanation:

In integer subtraction, find the additive inverse of the second number and then add.

Here additive inverse of (-3) is 3.

-8 - (-3) = -8 + 3

           = (-5)

If two numbers are opposite sign, subtract and the result will have the sign of the bigger number. Here the sign of bigger number (8) is negative.

7- (-8)

Here additive inverse of (-8) is 8

7 - (-8) = 7 + 8 = 15
