Is subtraction Commutative? Use an example to show your reasoning. I need help

OpenStudy (anonymous):

For example, when we say addition is commutative over the set of real numbers, we mean that a + b = b + a for all real numbers a and b. Subtraction is not commutative over real numbers since we can't say that a – b = b – a for all real numbers a and b.

OpenStudy (anonymous):

do you still need help?

OpenStudy (coldplay):

Yes I do.........
