There are different mathematical operations in math such as addition, subtraction, multiplication and division. Subtraction is of the basic and prominent mathematical operation used in every branch of math and life in general. Subtraction is denoted by the sign ‘-‘and is also called as difference. Subtraction means difference or the amount by which the total quantity is reduced. In subtraction the order in which the numbers are subtracted is very important. If the order of the numbers is changed the answer also changes. Hence subtraction is not commutative or associative.

Example 1: Subtract the following numbers and find the answer:
792 - 561?
Solution: Given are two numbers 792 and 561 which are both within 1000.
Subtracting the numbers 792 + 561.
First the one’s place is subtracted 2 - 1 = 1.
Now subtracting the ten’s place of the given numbers 9 - 6 = 1.
Then subtracting the hundred’s place of the numbers = 7 – 5 = 2.
Hence the subtraction of: 792 - 561 = 211.
