Integers are a set of whole numbers that include zero, positive numbers, and negative numbers.

They do not have any fractional or decimal components. Integers can be represented on the number line, and they include both the natural numbers (1, 2, 3, ...) and their negatives (-1, -2, -3, ...) along with zero.

Mathematically, the set of integers is denoted by the symbol "Z."

The integers are an essential part of mathematics and are used in various mathematical operations, including addition, subtraction, multiplication, and division. Examples of integers include -3, -2, -1, 0, 1, 2, 3, and so on.
