11/22 -- Group A: Divisibility, gcd's, and lcm's Part II (Mike, 6221) Combinations, Colored Picross
In Mike's group, we will continue our study of greatest common divisors and least common multiples, and their application to problems in modular arithmetic and remainders. In Carey's group, we look more at combinations and several cases with choosing 2 or 3 objects from a larger set. We also do a colored picross where different colors do not necessarily need to be separated by squares.
