Adding the opposite of a number to the same number will equal to \(0\) (zero).
Inverse property of addition: For every integer (\(a\)) there exists another opposite integer (\(-a\)) such that:
Where \(a\) is an integer, the additive inverse of \(a\) is \(-a\).
1. Additive inverse of \(a\) is \(-a\).
2. Addition and subtraction are inverse operations of each other.
