Media Summary: Oops, 679 also equals zero in mod 7 but does not satisfy N=5 (mod 6) condition, so answer is still correct. This identity is usually demonstrated in the opposite direction: n = 100a + 10b + c n = 100a + 10b + c (mod 9) Now substitute ... a ≡ b (mod n) means (1) same remainder upon ÷n (2) a = kn + b
