Identify Additive Inverse

Identify Additive Inverse : Algebra Help

If we have two variables such that a + b = 0, then a is the additive inverse of b. The additive inverse of an element a is the element a' such that a + a' = a' + a = 0 (0 is the additive identity). The additive inverse of a is denoted -a. It also demonstrates the representation of the additive inverse on the number line.
