How is the additive inverse property related to the additive identity property?

Additive inverse just means that when you add them, it equals 0. So, 1 and -1; 12 and -12; -74 and 74; 0 and -0. It can also be applied to things other than integers:x+12 and -x-12; 2x-3 and -2x+3...

It is used to show the inverse (opposite of a number) in algebra.

The additive identity for a set is a number (denoted by 0) such thata + 0 = 0 + a = a for all elements a which belong to the set.

the additive inverse property states that a number plus it's opposite equals zero. in other words, x + (-x) = 0 example: 5 + (-5) = 0

The sum of any number plus 0 yeilds the same number.
