1. Prove that the relation "divides" on the integers is reflexive and transitive.
2. Let A = {0, 1, 2, 3) and let r = {(0, 0), (1, 1), (2, 2), (3, 3), (1, 2), (2, 1), (3, 0), (0, 3) } be a relation on A. Show that r is an
equivalence relation, list all the equivalence classes, and explain why the equivalence classes form a partition of A
