Question

how can you subtract integers?

Answer 1

If both signs are positive, the answer will be positive.
Example: 15 - (-7) = 15 + 7 = 22If both signs are negative, the answer will be negative.
Example: -15 - (+7) = -15 - 7 = -22If the signs are different subtract the smaller absolute value from the larger absolute value. The sign will be the sign of the integer that produced the larger absolute value. 
Example: 15 - (+7) = 15 - 7 = 8
Example: -15 - (-7) = -15 + 7 = -8

Answer 2

Hi there!

Explanation: Additive inverse is the opposite of a number; the sum of additive inverse is zero. An integer and its additive inverse make up a zero pair.

Example: 4

Integer: -4  -4+4=0

Additive inverse: 4-4=0

Hope this helps!
