## Additive Inverse Formula

The following formula is used to calculate an additive inverse.

X = y * (-1)

X+y = 0

- Where X is the additive inverse
- y is the original integer

## Additive Inverse Definition

**What is an additive inverse? **An additive inverse is defined as a number that when added together with an original number has a sum of 0.

## Additive Inverse Example

**How to calculate additive inverse? **

- First, determine the original number. For this example, the original number is known to be 45.
- Next, use the formula above to calculate the additive inverse. So, 45*(-1) = -45.
- Check this value when added with the original number equals 0. (45+(-45)) = 0.
