Additive Inverse Property of 1

<-- Enter a number.

Using the number 1, demonstrate the Additive Inverse Property

For any number A, the Additive Inverse Property states:
A + (-A) = 0

Using our number that we entered of 1, we need to know if:
1 + (-1) = 0

Evaluating, we get 0 = 0

Since 0 = 0, we have proven the Additive Inverse Property using the number 1.
