2/14 -- Group A: Mikes group: Proofs in Modular arithmetic (continued), Clint's group: Divisibility and Primes
In Clint's group we'll continue divisibility, with special attention to the role of prime numbers.
As Mike is out of town Olga Radko will lead Mike's group. See last week's attachment for the handout "Well-definition of multiplication modulo n".
