The classifications of numbers are as follows:

1. Natural Numbers (N): These are the counting numbers starting from 1 and going up to infinity. Natural numbers include 1, 2, 3, 4, 5, and so on.

2. Whole Numbers (W): Whole numbers are the numbers that include all the natural numbers along with zero (0). So, whole numbers are 0, 1, 2, 3, 4, 5, and so on.

3. Integers (Z): Integers are a set of whole numbers that include all the positive numbers, negative numbers, and zero. They are represented as -3, -2, -1, 0, 1, 2, 3, and so on.

4. Rational Numbers (Q): Rational numbers are the numbers that can be expressed as a ratio (or fraction) of two integers. They can be positive, negative, or zero. Rational numbers include numbers like 1/2, -3/4, 5, -7, 0.25, and so on.

5. Irrational Numbers: Irrational numbers cannot be expressed as a ratio of two integers or as a fraction. They are non-repeating and non-terminating decimals. Examples of irrational numbers include √2, π (pi), and e (Euler’s number).

6. Real Numbers (R): Real numbers encompass both rational and irrational numbers. They include all the numbers found on the number line, such as fractions, decimals, and integers.

7. Complex Numbers (C): Complex numbers are numbers in the form a + bi, where “a” and “b” are real numbers, and “i” is the imaginary unit (√-1). Complex numbers are used to represent quantities involving the square root of negative numbers or imaginary numbers.

These classifications help categorize different types of numbers based on their properties and relationships. Understanding these classifications is important in various branches of mathematics, such as algebra, number theory, and calculus.
