a. Recall that the set Z of integers is the set of equivalence classes {[(a, 6)] | a, 8 e N}, where the equivalence relation v on the set N x Nis defined as (a, b) ~ (c, d) A a+d = 6+ e for any (a, 5), (c, d) eN x N so that the equivalence class of (a, b) is gives as [(a, 6)] = {(e, d) | (a, 8) ~ (c, d)} . For instance, 1 = [(1,0)] according to this notation of integers. Let * = [(28, 34)] , y = [(8, 44)] € Z. Find a + y and a - y. * + y =
