Fundamental operations on Whole Numbers

The fundamental operations on whole numbers are addition, subtraction, multiplications, and division.

-->

Addition: Addition means combining parts to get a whole.

Example: Meena has 5 chocolates in her purse. Her mom gave her 7 more chocolates. How many chocolates does she have in total?

Total Chocolates in Meena’s Purse = 5 chocolates + 7 Chocolates = 12 Chocolates.

Subtraction: Subtraction is the study of arithmetic operation for finding the difference between the two quantities or numbers.

Example:

1) 6 - 6 = 0

The value 6 minus value 6 equal to 0

The solution is 0(zero).

2) 12 – 24 = - 12

The value 12 minus value 24 equal to minus 12

The solution is minus 12

Multiplication: Multiplication is one type of arithmetic operations and repeated one number to the number of times equal to the other number. Symbol used for subtraction (x).

Example: 229*101 means 101 times 229

= 100 times 229 + one time 229 ( by using multiplication method)

= 22900 + 229

= 23129

Division:

-->Division is one type of arithmetic operations and it is the process of repeated subtraction. Symbol used for division (÷).

Example: Divide 40 by 8

Solution:

40

– 8 … (1)

____

32

– 8 … (2)

____

24

– 8 … (3)

____

16

– 8 … (4)

____

8

– 8 … (5)

____

0

____

So, 40 is divided by 8 in 5 times

40 ÷ 8 = 5
