- There are various badges quizzes for you to try and a proof quiz due Friday. I’m open to special requests, BTW, to have more copies of certain badges.
- Wednesday in class we introduced modular arithmetic. If you missed, please watch the video for a thorough explanation, including of how to do the associated worksheet. Do the worksheet.
- In the video I state several theorems for you to try to prove on your own. Try them.
