Practice and Homework Problems
For each chapter, I will give you a list of suggested practice problems for you to review and solve. Sometimes
I will assign certain sections as homework. You will also receive practice worksheets that I usually collect for a
homework grade. For anything that I don’t grade as an assignment, I will post the answers in the homework
binder on my desk for you to check.
