9. Modular Arithmetic
...and 0 = false for logic questions and that 1 + 1 = 0 (two truths make a false). Development: Procedure Elaborate by showing them the notation of (mod m) or (mod 2) in the case of binary. Explain what mod = modulo is and how it is used. Continue by moving into (mod 3), (mod 5) and (mod 7) (or other primes). By using prime numbers, addition and multiplication are preserved. If a non-prime is used, then only addition will work. Closer: Play a game with them. Have them pick a (small) prime or non-prime, call it n, and then pick two numbers between 0 and n. Then start adding them like in the Fibonacci series (a...
