Answer:
-20 + 20 = 0
20 - 20 = 0
Explanations:
According to the inverse property of addition, the sum of a number and its inverse is equivalent to zero. For instance, the inverse of A is -A since their sum is zero.
From the options, the correct application of inverse property will be the expression that supports the law above. The correct expressions are:
-20 + 20 = 0 (-20 and 20 are inverses)
20 - 20 = 0 (20 and -20 are inverses)
