10.5 part 1 due 11/9/12

1. I assume that "up to" means up to and including so I read theorem 10.18 in addition to the pages before it and I would have to say the most difficult thing to understand was The Schroder–Bernstein Theorem, then again it was all difficult.
2. I found it very difficult to understand anything in this section. This is probably because I have a hard time understanding all of chapter 10. Math is all about building on idea on another. If we can't understand how to add/sub and mult/div then we can not understand how to do algebra. Same concept applies to me with this class. I need to be able to understand the section before or how can i expect to understand this new section.
