To Know: Lots of sets badges available for Friday! Work hard on them — once you get perfect on a badge, you have earned it and don’t need to repeat. Very soon I will post a proof to be due Monday also. The Sets III badge is open for the “Oral Exam” — arrange with me or show up at office hour with your study sheet according to the instructions in the Grading page.

For a daily task for today, find me a cool graph on the internet related to something you find interesting. Just submit an interesting link on the daily post dropbox.

Also, think about what the “Truth Tables” should be for OR and NOT (the question I ended class with).

You have a lot of sets badges due Friday, so with the rest of your time just prepare and/or work on those.
