Rule:

Positive + Positive = Positive

12+12=24

Positive - Positive = Positive or Negative

12-6=6 | 12-13=(-1)

14+(-18)=(-4) | 18+(-14)=4

Positive - Negative = Positive

8-(-8)=16

Negative + Negative = Negative

-12+(-12)=(-24)

Negative - Negative = Positive or Negative

(-8)-(-9)=1 | (-8)-(-7)=(-1)
