Integers are a fundamental concept in mathematics. They are the set of whole numbers and their negatives, including zero. Integers can be represented on the number line, with positive integers to the right of zero and negative integers to the left.

Integers are used in various mathematical operations, such as addition, subtraction, multiplication, and division. They are commonly encountered in everyday life, such as when counting money, measuring temperatures, or keeping track of scores.

The set of integers can be denoted as ℤ or {…, -3, -2, -1, 0, 1, 2, 3, …}. This infinite set extends in both positive and negative directions without bound.
