Homework should be turned in at the BEGINNING OF CLASS. All problem numbers refer to Bilodeau and Thie's book, the required text for the course. You should write up solutions neatly to all problems, paying particular attention to your arguments and proofs. A nonempty subset will be graded. You are strongly encouraged to work on these problems with other classmates, although the solutions you turn in should be your own work.

**Section 1.2**

Problems: 5 (all parts), 7 (all parts), 11

**Section 1.3**

Problems: 1 (parts e, f), 8 (all parts), 9 (parts a, b, d)

For problem #1, be sure to state the axiom or law which justifies each step of your proofs.
