This lecture doesn't really correspond to any continuous section of Callister; it is background to a lot of Chapter 9, and bits of Chapter 10. It's also very short (though the next lecture is rather long.)
The assignment for this week is:
Assignment for Week 5, Due Monday, Feb 9
You should read both the assigned chapters, but topics covered on the website associated with the textbook, or with the CD that comes with the 6th edition will not be examined in the mid-term or final exams.
