Following the notation of the theorem, we have m 1 = N=5 = 77, m 2 = N=7 = 55, and m 3 = N=11 = 35. We now seek a multiplicative inverse for each m i modulo n i. First: m 1 77 2 (mod5), and hence an inverse to m 1 ...

Equivalence Relations - Mathematical and Statistical Sciences
www-math.ucdenver.eduModular Arithmetic Theorem: For any natural number m, the modular relation ≡ m is an equivalence relation on ℤ. Pf: For any x in ℤ, since x – x = 0 and m | 0, x ≡ m x. (Reflexitivity) If x ≡ m y then m | x – y. Since y – x = -(x-y), m | y – x, and so, y ≡ m x. (Symmetry) If x ≡ m y and y ≡ m z then m | x – y and m | y ...
