2/7 -- Group A: Divisibility (Clint), Proofs in Number Theory, ctd (Mike)

Clint, 6201: Our group has been studying parity, or divisibility by 2. This week we'll enlarge our focus and start looking at divisibility in general.

Mike, 6221: We will go over the worksheet "Well-definition of addition modulo n", and continue our study of modular arithmetic from a rigorous logical perspective.
