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.
