Answer:

additive inverse

Explanation:

The equation shows that the sum of a number and its additive inverse is zero. This is the additive inverse property.

_____

Additional comments

This property is used, together with the identity property of addition, to solve equations by making terms disappear where you don't want them.

Example:

x + 1 = 3

We would like to remove the +1 in order to find the value of x. Using the additive inverse property, we add the additive inverse of +1 to both sides of the equation.

x +1 -1 = 3 -1

The additive inverse property tells us the sum of +1 and -1 is zero, so this becomes ...

x +0 = 2

The additive identity property tells us the sum of x and 0 is simply x, so ...

x = 2
