What is Number?

A number is a mathematical object used to count, measure, label, and more. You can also say Number is a Combination of the digit. For example: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 ……………..

Type of Numbers

There are various types of Numbers which are mention below with examples for better understanding. You must be learning every number which is to help you to understand the number and Math calculation. You must be remembering each and everything about the number and type of number from the beginning.

Type of Numbers

1). Natural Number 

A natural number is also called a counting number such as 1, 2, 3, 4, 5, 6, 7 ……….… infinitive. The natural number is represented by N. 

2). Whole Number 

The whole number is starting from zero to-infinitives or zero with Natural numbers such as 0, 1, 2, 3, 4, 5, 6, 7, ………..infinitive. The whole number is represented by W.  

3). Integers

Integers are natural number and negative natural number with 0 that is called integers. For example: infinitive ……………..-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5 …………….. Infinitive. An integer is represented by Z. there are Two types of Integer:

  • Positive Integers: positive integers are a set of the whole number. For example: 0, 1, 2, 3, 4, 5, 6, 7, ………….
  • Negative Integers: Negative Integers are a set of natural numbers with a negative sign. For example: ……………….-5, -4, -3, -2, -1 .  

4). Rational Numbers 

A number that can be written in the form of p/q and q is not equal to zero that is called a rational number. All Natural numbers, integers are a rational number. A rational number can be represented by the letter “Q”. for Examples: 7/1, 10/2, 1/1, 0/1, ……. 

5). Real Numbers 

Real Number is a set of numbers including natural number, whole number, integers, rational number, and irrational numbers. For example: ¾, 0.333, √2, 0, -10, 20, ………..

6). Irrational Number 

The number that cannot be expressed in the form of p/q, is represented by P. for example √2, π, Euler’s constant, ………. 

7). Complex Numbers 

A complex number that is written in the form of a+bi is called complex numbers, where “a and b” should be a real number, and “i” is an imaginary number. For Examples: 4 + 4i, -2 + 3i, 1 +√2i, ………

8). Prime Numbers

Numbers that are divisible by only 1 and themselves are called Prime numbers. For Example: 1, 2, 3, 5, 7, 11, 13, 17, 19,23, 29, …  

9). Composite Numbers

Numbers that are divisible by numbers other than 1 and themselves are called composite numbers. For Example 4, 6, 8, 9, 10, …… 

10). Even Number 

Even Numbers are evenly Divisible by 2 which is called Even number. Or numbers that end with a 0, 2, 4, 6, 8, are called even number. For example: 2, 4, 6, 8, 10, 12, 14, 16, 18………     

11). Odd Numbers 

Odd Numbers are not evenly divisible by 2. They always leave a reminder that is called Odd numbers. Or numbers that end with a 1, 3, 5, 7, 9, are called Odd number. For example: 3, 5, 7, 9, 11, 13, 15, 17, 19, 21………  

Number Representations 

We are going to share the Number representations. 

1). Fraction Numbers 

A number that can be written in the form of the Nominator/Denominator. For Example7/1, 10/2, 1/1, 0/1, ……. 

2). Decimal Number

A Number is separated by a decimal point that is called decimal number. For example: 2.3456, 7.42, 6.234, 6.543……….. 

3). Binary Numbers 

A number expressed in the base-2 numeral system. Typically 0 and 1 is a binary number.

Signed Numbers 

1). Negative Numbers 

A Number represents the negative sign that is called a negative number. For example: -2, -3, -3/4,…… 

2). Positive Numbers

A Number represents a positive sign that is called Positive number. For example 2, 3, 3/4,………..
