 Additive Inverse:  The sum of a number and its additive inverse is zero.
What happens when you add two numbers that are opposites, like 5 and -5? In a sense, they "cancel" each other, resulting in zero. In other words, the sum of a number and its additive inverse is zero.

Examples of Additive Inverse Property

2 + (-2) = 0

x + (-x) = 0

-0.5 + 0.5 = 0



Non-Examples of Additive Inverse Property

2 + (-1) = 1

5 + (-6) = -1
