For (a, b), (c, d), (e, f) A A × ?
If (a, b) R (c, d) & (c, d) R (e, f) i.e. a + d = b + c & c + f = d + e
Adding, a + d + c + f = b + c + d + e ? a + f = b + e
then (a, b) R (e, f) ? R is transitive 1 m
? R is reflexive, symmetric and transitive
hence R is an equivalance relation ½ m
[(2, 5)] = {(1, 4), (2, 5), (3, 6), (4, 7), (5, 8), (6, 9)} ½ m
