Using the electronic version of the text book (http://ebooks.cpm.org), attempt the problems listed below. If you get stuck on a problem and can get help from a friend or family, that's great, but it is not necessary for you to research a problem if you are not sure how to solve itâ€”just give it your best effort.

Important: Be sure to show your work! There is no credit for just the answer (because the answers are given in the e-book and textbook).
