Whole numbers is the set of all positive numbers including zero. All positive numbers, negative numbers and zero make up the set of integers. The fractions are known as rational numbers. There are four basic mathematical operations, that is, addition, subtraction, multiplication and division, and these operations can be performed on all real numbers. Adding two numbers will get the sum and subtracting two numbers will get their difference. Multiplication is a short form of addition and division is a short form of subtraction. These operations can be performed whole numbers, integers, rational numbers, irrational numbers and even on imaginary numbers. In imaginary numbers reals parts and imaginary parts are taken separately.

The non negative integers has series like 0, 1, 2, 3 and so on.

The positive integer series has 1, 2, 3 and so on.

The another name of whole number is counting numbers.

The basic operations of numbers are as follows:

- Addition
- Subtraction
- Multiplication
- Division

The whole numbers are added to one another. This is similar to counting because it gives the total value of numbers. The whole number addition operation is represented as ‘ + ’.

The given two numbers are 12 and 13.

1 2

_

Therefore, the value of addition for 12 and 13 is 25.

The given two numbers are 26 and 43.

26

Therefore, the sum of 26 and 43 is 69.

Difference of any two whole numbers is calculated by subtraction operation. As per the rule, small whole number is subtracted from large number. The symbol ‘ - ‘ is represent the subtraction operation.

We have to subtract 56 from 14

5 6

So the difference is 42

We have to subtract 37 from 16

37

__- 16____ 21__

So the value after subtraction is 21.

37

So the value after subtraction is 21.

Multiplication of two whole numbers is represented by ‘ x ’ symbol. We can also make use of the multiplication table to cross check the product.

The given two numbers are 14 and 4.

1 4

__x 4__

__5 6__

Therefore, the value of multiplication is 56.

1 4

Therefore, the value of multiplication is 56.

The given two numbers are 24 and 5.

24

__x 5__

__120__

Therefore, the product is 120.

24

Therefore, the product is 120.

The last basic operations in math is division and is represented by ‘ ÷ ’ symbol.

This operation may also give the remainder value on division.

The given numbers are 12 and 2

____6_______

2 | 12

__(-)12______

0

Number after division is = 6

The given numbers are 28 and 7.

____4_______

7 | 28

__(-)28______

0

Number after division is = 4

__

7 | 28

0

Number after division is = 4
