Definition: Integers
The numbers −1, −2, −3, … (to the left of zero) are negative numbers or negative integers, and the numbers 1, 2, 3, … (to the right of zero) are positive numbers or positive integers.
Hence, the new set of numbers …, −3, −2, −1, 0, 1, 2, 3,… are called integers.
Additive Inverse: In mathematics, the additive inverse of a number a is the number that, when added to a yields zero. This number is also known as the opposite number. For example, - 5 + 5 = 0.
