Which law is represented by the relation m + n = n + m?

Answer and explanation

Correct answer: Commutative law

Changing the order of the addends does not change their sum; that is, m + n = n + m. This is the commutative law of addition. The distributive law involves multiplying across a sum or difference, such as a(b + c) = ab + ac. Exam tip: the commutative law changes the order, whereas the associative law changes the grouping.
