Integers are whole numbers that can be positive, negative, or zero. They include numbers like −1, 0, 1, and continue infinitely in both directions. Integers do not have fractions or decimals, making them simple and straightforward to work with in mathematics. In everyday life, integers are used in various contexts, such as measuring temperature, counting items, or tracking scores in games. They form the basis for more complex mathematical concepts and are essential for operations like addition, subtraction, multiplication, and division.
