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:

  • 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.

Mathematics provides a precise and systematic way of expressing relationships, patterns, and structures. It is often regarded as a foundation for scientific and technological advancements. The ability to think logically, analyze data, and solve problems is highly valued in many professions, making mathematics an essential skill in various aspects of life and academia.
