An integer is a mathematical term that refers to a whole number that can be positive, negative, or zero
An integer is a mathematical term that refers to a whole number that can be positive, negative, or zero. It does not include fractions or decimals. Integers can be thought of as the set of numbers that includes both the counting numbers (1, 2, 3, …) and their negatives (-1, -2, -3, …), as well as zero (0). In other words, any number that can be written without a fractional or decimal part is an integer.
For example, -5, -3, 0, 2, and 7 are all integers. However, numbers like 1.5, -0.8, and 3/4 are not integers because they have fractional or decimal parts.
Integers are used in various areas of mathematics, including algebra, number theory, and arithmetic. They are widely used in everyday life for counting objects, representing temperatures, measuring distances, and many other practical applications. Integer arithmetic involves addition, subtraction, multiplication, and division of these whole numbers.
