In Carey's group, we will go over the homework, and begin applying what we have learned so far to counting with repetitions and the idea of a "combination." Attached are last week's handouts and the homework. In Mike's group, we will review/introduce the notions of least common multiple and greatest common divisor. Euclid's method, and various realizations of gcd's will be covered.⊟Details

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. ⊟Details
