Homework 11 was a stretch for some and perhaps lesson 12 should be split. This series of lectures on numbers are in many ways a dream come true, but still require continued work. The odd answers helped in this revision, but the homework doesn't quite do what I want. The projects done last year still need to be made available to students. It is planned for Center students to take some responsibility to clarify the less clear and extend the more interesting aspects.
Continued feedback is appreciated.
Revised on or after September 25, 2000.
