This lesson explains the concept of the additive inverse and gives you several examples to understand
it in depth. It also illustrates the representation of the additive inverse on the
number line. Overall, if a + b = 0, then a is the additive
inverse of b.You can also say, the additive inverse of an element a is the element a' such that a + a' = a' + a = 0. Usually, the additive inverse of a is denoted -a.
