Lecture 22

We did examples from chpater 18 (Sets of Sets).

Announcements

• The exams are almost done but we won't make discussions today. Will probably get exams back in Friday discussions. Others can pick up on Friday or at office hours after break. Watch piazza as details emerge.
• The mini-homework after break will be due on Wednesday, since I'm guessing you won't get started on it until you get back to campus over the weekend. [In class I actually said Tuesday, but later pushed it even further forwards.] The next homework (9) will also be due on Wednesday, but it will be short.
