11/15 -- Group A: Counting With Repetitions (Carey, 6201), Divisibility, gcd's, and lcm's Part I (Mike, 6221)
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.
