Integers are a set of numbers that include positive whole numbers (1, 2, 3, …), negative whole numbers (-1, -2, -3, …), and zero (0). In other words, integers are numbers that are not fractions or decimals. Integers can be represented without any fractional or decimal part.

Integers are typically denoted by the symbol “Z” and are useful in various mathematical operations and concepts. They have many properties and rules that are unique to this number set.

Some key properties of integers include:

1. Closure: When you add, subtract, or multiply two integers, the result is always an integer.
2. Ordering: Integers can be arranged in order from smallest to largest or vice versa. For example, -3 < -2 < -1 < 0 < 1 < 2 < 3. 3. Addition: Adding two integers may result in a greater integer (positive + positive or negative + negative), a smaller integer (negative + positive), or zero (positive + negative), depending on the sign of the numbers. 4. Subtraction: Subtracting an integer from another integer also follows similar rules as addition. 5. Multiplication: When multiplying two integers with the same sign (both positive or both negative), the result is positive. If the signs are different, the result is negative. 6. Division: Dividing an integer by another integer may result in a quotient and a remainder. It is important to note that dividing by zero is undefined. Integers are widely used in various branches of mathematics, including algebra, number theory, arithmetic, and more. They are essential in solving equations, working with inequalities, and understanding number patterns. Integers are also applied in real-life situations, such as counting, measurements, temperature scales, and even financial transactions.
