Homework should be turned in at the BEGINNING OF CLASS. All problem numbers refer to McCallum, Hughes-Hallett, et al., the required text for the course. You should write up solutions neatly to all problems, making sure to SHOW ALL YOUR WORK. 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.
