What is a counterexample for "subtraction of whole numbers is commutative" ??
devlian [24]
The commutatice property for addition says a+b=b+a
If it was for subtraction, then it would be a-b=b-a
Take a=7 and b=5
7-5 is not equal to 5-7
2 is not equal to -2
So subtraction is not commutative for whole numbers.

Hope this helps :)
