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?

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