An additive inverse of a number is defined as the value, which on adding with the original number results in zero value. It is the value we add to a number to yield zero. Suppose, a is the original number, then its additive inverse will be minus of a i.e.,-a, such that;

a+(-a) = a – a = 0

Example:

Additive inverse of 10 is -10, as 10 + (-10) = 0
Additive inverse of -9 is 9, as (-9) + 9 = 0
Additive inverse is also called the opposite of the number, negation of number or changed sign of original number.

Fact: Additive inverse of zero is zero only.
