2/1/2009: Group A: Counting strategies;
Group B: Unique factorization in exotic number systems (Prof. Jared Weinstein)

Group A: As homework for next Sunday, please read Sections 1.4-1.5 and 2.1-2.3 (as far as page 37) and do the following exercises:
1.4.4
1.5.1(a)-(d), 1.5.3(a)-(c)
2.2.2, 2.2.3
2.3.1, 2.3.4
Challenge: 1.34, 1.36, 2.28, 2.32
Group B: We will continue learning about quadratic residues and unique factorization for Gaussian integers and some other number systems.
