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
