Let n be a given natural number. The Congruence modulo relation is defined thus: a ≡ b (modulo n ) ⇔ n a − b ⇔ a − b = nk for some k ∈ ℤ. To say that n divides a − b is to say that a − b = nk for some integer k. For example, we can write 38 ≡ 14 (mod 12), because 38 − 14 = 24, which is a multiple of 12.
