1. Vocabulary What operations have inverse relationships?

Addition and subtraction are inverse operations, Multiplication and division are inverse operations.Another pair of inverse mathematical operations is raising a number to an exponent "n" and taking the nth root of the number.

In mathematics, an inverse operation is an operation that undoes what was done by the previous operation. The four main mathematical operations are addition, subtraction, multiplication, division.
