If you are going to read what is called a Whole Numbers on this page, then definitely read the article completely.

On the previous page, we have shared information about **Odd Numbers**, so do read odd numbers.

Let us read and understand the properties and rules of what is called a whole number on this page.

## Whole Numbers Definition

All positive natural numbers from 0 to infinity are called whole numbers.

The **Whole Numbers** are the number without fractions and it is a collection of positive integers and zero.

It is represented by the symbol “W” and the set of numbers are {0, 1, 2, 3, 4, 5, 6, 7, 8, 9,……………}. Zero as a whole represents nothing or a null value.

**Whole Numbers : W =** {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10……}

**Natural Numbers : N = **{1, 2, 3, 4, 5, 6, 7, 8, 9,…}

**Integers : Z =** {….-9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9,…}

**Counting Numbers :** {1, 2, 3, 4, 5, 6, 7,….}

These number are positive integers including zero and do not include fractional or decimal parts (3/4, 2.2 and 5.3 are not whole number).

Also, arithmetic operations such as **Addition**, **Subtraction**, **Multiplication** and **Division** are possible on whole number.

### Symbol

The symbol to represent whole number is the alphabet ‘W’ in capital letters.

W = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,…}

Thus, the **whole numbers list** includes 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, ….

## Rules of Whole Numbers

**There are 6 properties of whole numbers.**

- Closure properties of whole number
- Commutative rule of addition
- Commutative rule of multiplication
- Associative law of sum
- Associative rule of multiplication
- For whole number, multiplication over addition is distributive.

### 1). Closure Properties of Whole Numbers

Whole number are closed under addition and multiplication. Adding or multiplying any two whole number gives a whole number.

**Example :-**

7 + 2 = 9, 7 x 9 = 63

Hence 9, 63 is a whole number.

### 2). Commutative Rule of Addition

Whole number follow the commutative rule in addition. Adding any 2 or more than 2 whole number in any order gives the same answer.

**Example :-**

- 1 + 2 + 3 + 4 + 5 = 15
- 5 + 2 + 4 + 1 + 3 = 15

### 3). Commutative Rule of Multiplication

Whole number follow the commutative rule in multiplication. Multiplying any 2 or more than 2 whole number in any order gives the same answer.

**Example :-**

- 9 × 6 = 54
- 6 × 9 = 54

### 4). Associative Law of Sum

All whole number follow the associativity rule in addition.

### 5). Associative Rule of Multiplication

All whole number obey the multiplication associative rule.

### 6). For Whole Number, Multiplication over Addition is Distributive.

### Difference Between Whole Number and Natural Number

Let us understand the difference between natural number and whole number with the help of the table given below :

Whole Numbers | Integer Number |
---|---|

All positive natural numbers from 0 to infinity are called whole numbers.For example :- 1, 2, 3, 4, 5, 6, 7, 8, 9 …………….infinite | The numbers made up of positive, negative and zero are integer numbers.Ex : -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5 |

The set of whole numbers is represented by ‘W’ (Whole Number). Whole numbers (W) = 1, 2, 3, 4, 5, 6, 7, 8, 9………..infinite | The set of whole numbers is represented by ‘I’ (Integer Number). Integer numbers (I) = -4, -3, -2, -1, 0, 1, 2, 3, 4, |

All natural numbers are whole numbers. But all whole numbers are not natural numbers. | All whole numbers and their negative numbers are called integers. |

**Facts :**

- All the natural number are whole number
- All counting number are whole number
- All positive integers including zero are whole number
- All whole number are real number
