Set of integers

A set of integers is a collection of whole numbers that can be positive, negative, or zero, without any fractions or decimals. Think of it as a list of numbers like -3, 0, 4, and 7, where each is distinct. These numbers are used to count, measure, or represent quantities in various contexts. The set of integers includes all positive numbers, their negatives, and zero, and is often denoted by the symbol ℤ. This concept helps organize and work with whole numbers systematically in mathematics and related fields.
