Subtraction of whole numbers is commutative. True or False
strojnjashka [21]
It is False.

If a property is commutative in subtraction it means:  x - y    is the same as y - x.

For example    5 - 3 = 2,  but 3 - 5 = -2  so subtraction is not commutative.

But 5 + 3 = 8   ,   is the same as 3 + 5 = 8.

Addition is Commutative, but Subtraction is not commutative.

So the statement that subtraction of whole numbers is commutative is False.
