exercises for Week 1, Aug 19 to Aug 23

Our two plus two hours per week (Mon 14-16 and Thu 10-12) will be a mix of lectures, exercises, and stories, from PartOne and PartTwo. The material will partly be covered by carrying out and  going through exercises, as opposed to "the professor is lecturing". I'm hoping for active participation from you, the students, also *partly* by having you going to the blackboard to go through your solutions to exercises. 

For Week 1, Aug 19 to Aug 23, attempt to work through these exercises from Ch 1: 1, 2, 3, 4, 8, 9, 10, 12, 15, 16.
