## How is the term inverse used in arithmetic operations? |

Inverse operations are those that “undo” another operation. In particular, subtraction is the inverse of addition because a + b - b = a; division is also the inverse operation to multiplication.

The *inverse of a number* can be expressed as follows: The additive inverse of a real or complex number *a* is the number that, when added to *a,* equals 0. In multiplication, the multiplicative inverse of *a* is the number that, when multiplied by *a,* equals 1.
