An integer is a whole number, (no fractional part); it can be positive, negative or zero.
It is a subset of real numbers than can have fractional parts or decimal digits or be irrational.
A sum of any two integers of same magnitude but opposite sign can be zero.

0 + 0 = 0

The sum of two integers can be zero.
An integer (from the Latin integer meaning "whole") is a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, 5 ⁄2, and √2 are not.
