## Whole Numbers Definition

If zero is also included in the natural number( 1, 2, 3, 4, 5, 6, 7 …. ∞ ), then those numbers are Whole numbers.ex – 0, 1, 2, 3, 4, 5, 6, 7, 8 ……. ∞

If W is removed from the word whole, the word becomes a hole word. And we know. That the hole size looks like zero. So from the hole, we will remember zero. Numbers from 0 to infinity are called hole numbers.

### Number Line

## Whole Numbers Examples

555, 687, 999, 0, 1800, 1520, 888 etc.

## The predecessor of the whole number

The predecessor of the whole number is that number. Which comes 1 digit before the given number. That is, 1 is subtracted from that number to find the predecessor of a whole number.

Ex – What will be the predecessor of 555?

We know To find the predecessor of any number, one is subtracted from that number. Hence the predecessor of 555 is (555-1) = 554.

What will be the predecessor of 2?

Ans – (2-1) = 1

Subtract one of them to find the predecessor of two.

## The successor of the whole number

The successor of a whole number is that number. Which comes after 1 digit of the given number. Or to find the successor of a hole number, one is added to that number.

Ex – What will be the successor of 15?

Ans – To find the successor of 15 can be obtained by adding a digit to it. 15 + 1 = 16

What will be the successor of 120?

120+1 = 121

## Property of Whole Numbers

### Closure Property

If two whole numbers are multiplied and added. So the number received is the whole number. On the other hand, if two whole numbers are divided and subtracted, the number obtained may or may not be a whole number.

#### Addition

The sum of two whole numbers is the whole number.

**Whole Number + Whole Number = Whole Number**

Ex – 2+2 = 4, 0+1 = 1, 5+8 = 13

#### Multiplication

Multiplication of two whole numbers is obtained as a whole number.

**Whole Number × Whole Number = Whole Number **

Ex – 2×2 = 4 , 5×8 = 40, 12×2 = 24

#### Subtraction

If the smaller whole number is subtracted from the larger whole number then the number obtained will be the whole number. Conversely, if the whole number is subtracted from the smaller whole number, the number received will not be the whole number.

**Whole Number “x” – Whole Number “y”** = **Whole Number ( x>y)**

Ex: 4 – 2 = 2, 10 – 5 = 5, 110 – 20 = 90, 999 – 111 = 888

**Whole Number “x” – Whole Number ‘y” = Whole Number (x=y)**

Ex: 4 – 4 = 0, 15 – 15 = 0, 50 – 50 = 0, 80 – 80 = 0

**Whole Number “x” – Whole Number “y” = integer ( x<y)**

Ex: 15 – 20 = -5, 40 – 50 = -10, 130 – 140 = -10

#### Division

The division of two whole numbers will be the whole number only if the dividend is completely divisible by the divisor.

In the above situation, only the whole number can be obtained in case of division. If the quotient is the point or negative. So the whole number will not be received.

### Commutative Property

The whole number follows the Commutative Property in addition and multiplication. On the contrary, it does or may not follow.

#### Addition

Two whole numbers can be added in any case, the whole number is obtained. According to the Whole Numbers Definition, these numbers range from zero to infinity

**Whole Number “a” + whole Number “b” = Whole Number “b” + Whole Number “a”**

a + b = b + a

Ex: 5 + 4 = 4 + 5 In this case, if 5 and 4 are added or 4 and 5 are added, the same answer will come in the two cases.

#### Multiplication

According to the Whole Numbers Definition, these numbers range from zero to infinity

**Whole Number “a” **x** whole Number “b” = Whole Number “b” **x** Whole Number “a”**

a x b = b x a

Ex: 5 x 4 = 4 x 5| In this case, if 5 and 4 or 4 and 5 are multiplied, the same answer will be given in two cases.

#### Subtraction

The whole number does not follow the Commutative Property in case of subtraction.

Ex: a – b ≠ b -a

#### Division

In the case of division, the whole number does not follow the Commutative Property.

### Associative Property

If three whole numbers are added or reduced in any case, then, in that case, the whole number is obtained. The whole number in addition and subtraction follows the Associative Property.

#### Addition

In the case of Yoga, the Whole Number follows the Associative Property.

Ex: (a + b) + c = a + (b + c)

#### Multiplication

In the case of multiplication, the Whole Number follows the Associative Property.

Ex: (a x b) x c = a x (b x c)

#### Subtraction

In the event of subtraction, the Whole number does not follow the Associative Property.

( a – b ) – c ≠ a – ( b – c )

#### Division

The whole number does not follow the Associative Property in the position of the part.

### Distributive Property

In the case of addition and multiplication, the Whole number follows the Distributive Property.
