There is no required text, but if you want a book I recommend Abstract Algebra by Thomas Judson. You can download it for free; be sure to get the latest edition. (I'm not following it or using itin any way.) Lecture notes are linked above, and homework will be posted here.
You can enter a short program to get a mod function if you have a TI 83 or 84.
[Sunday, February 11] I mailed everyone on Friday, but in case you didn't get it - Problem 2 on P.S. 8 (to find 83-1 (mod 101)) was removed, because we didn't do an example like that yet. We'll do a problem like that one on Monday, and P.S. 9 has a replacement problem of that sort. The problem sheet for P.S. 8 below has Problem 2 removed, so you should do all of the problems on it.
Solutions to the problem sets will be posted after the problem sets have been collected.
Review Sheets help you study for tests; they're not graded work that you have to turn in. Just because there's a problem on the review sheet doesn't mean that there will be a similar problem on the test. And there may be problems on the test which are different from the review sheet problems. You're responsible for all the material we've covered.
I used to hold in-person review sessions (I stopped due to poor attendance). These are notes for the review sessions. If there's any question, refer to the review sheet for the test to see what you're responsible for.
The notes and the videos are not in sync with the material for a given test! (So there may be material on them you're not responsible for, and there may be material not included that you are responsible for.)
These are videos for the review sessions. (They're a little old.) You'll see me writing solutions to selected problems as I talk through the answers. I don't do all of the problems in the printed notes above. Most of the review sessions are in parts, so the videos don't get too long and the files don't get too big.
(Repeated for emphasis) The notes and the videos are not in sync with the material for a given test! (So there may be material on them you're not responsible for, and there may be material not included that you are responsible for.)
If you're having personal problems: Please consider seeing Counseling Services. They're on the 3rd floor of Lyle Hall; they're free and confidential, and they've helped many of my students. It's natural to want to fix things yourself, but if your problems are causing you to miss class, to get behind in courses, or to get poor grades, it's best to get help.
