Explanation :
Subtraction is not Commutative for Whole Numbers, this means that when we change the order of numbers in subtraction expression, the result also changes.
Commutative Property for Subtraction of Whole Numbers can be further understood with the help of following examples :
Example 1 = Explain Commutative Property for Subtraction of Whole numbers 5 & 7 ?
Answer = Given whole numbers = 5, 7 and their two orders are as follows :
Order 1 = 5  7 = (2)
Order 2 = 7  5 = 2
As, in both the orders the result is different.
So, we can say that Subtraction is not Commutative for Whole Numbers.
Example 2 = Explain Commutative Property for Subtraction of Whole numbers 23 & 43 ?
Answer = Given whole numbers = 23, 43 and their two orders are as follows :
Order 1 = 23  43 = (20)
Order 2 = 43  23 = 20
As, in both the orders the result is different.
So, we can say that Subtraction is not Commutative for Whole Numbers.
Example 3 = Explain Commutative Property for Subtraction of Whole numbers 20 & 5 ?
Answer = Given whole numbers = 20, 5 and their two orders are as follows :
Order 1 = 20  5 = 15
Order 2 = 5  20 = (15)
As, in both the orders the result is different.
So, we can say that Subtraction is not Commutative for Whole Numbers.
