1. ### Help with showing that R is an equivalence relation?

I take it ℕ in this context refers to the set of natural numbers. To show a relation is an equivalence relation, we need to show that it is reflexive, symmetric, and transitive. Reflexivity: Clearly, for any natural number a, aRa...

2. ### m is said to be related to n if m and n are integers and m-n is diivisible by 13.does this define an equivalan?

...reflexive: n-n=0 and 13|0 so nRn R is symmetric: If mRn then 13|(m-n), i.e., m-n = 13k for some integer k. Then n-m = -13k = 13(-k...
