**what is number in maths , Mathematics, often referred to as “math,” is a field of study that deals with the properties and relationships of numbers, quantities, shapes, and patterns. It involves logical reasoning, analysis, abstraction, and problem-solving. Mathematics is a universal language and a fundamental tool in various fields, including science, engineering, economics, and computer science.**

**In mathematics, a number is a mathematical object used to count, measure, and label. Numbers can be classified into different types based on their properties. Here are some key categories of numbers:**

**What is number in maths : **

**Natural Numbers (N):**- These are the counting numbers: 1, 2, 3, 4, 5, and so on. They start from 1 and go infinitely.

**Whole Numbers (W):**- Similar to natural numbers, but including zero: 0, 1, 2, 3, 4, 5, and so on.

**Integers (Z):**- Integers include all positive and negative whole numbers, as well as zero: …, -3, -2, -1, 0, 1, 2, 3, …

**Rational Numbers (Q):**- These are numbers that can be expressed as fractions where the numerator and denominator are integers, and the denominator is not zero. Examples include 1/2, -3, 5/7, and so on.

**Irrational Numbers:**- Numbers that cannot be expressed as fractions of integers. Examples include the square root of 2 (√2) and pi (π).

**Real Numbers (R):**- Real numbers include both rational and irrational numbers. They represent all points on the number line.

**Complex Numbers (C):**- Complex numbers have a real part and an imaginary part. They are written in the form a + bi, where “a” and “b” are real numbers, and “i” is the imaginary unit (equal to the square root of -1).

**Prime Numbers:**- Natural numbers greater than 1 that have no positive divisors other than 1 and themselves. Examples include 2, 3, 5, 7, 11, and so on.

**Odd and Even Numbers:**- Natural numbers are classified as either odd or even. An even number is divisible by 2 without a remainder (e.g., 2, 4, 6), and an odd number is not (e.g., 1, 3, 5).

**These are just a few categories of numbers in mathematics, and the study of numbers is a fundamental part of mathematical theory and practice. The properties and relationships among different types of numbers form the basis of various mathematical concepts and applications.**
