- Final exam,
**Thu Dec 12, 9:45am-noon**, in:

**Boccardo Business Complex 126.**

Click here for a google map of BBC. - The textbook for this class is Gallian's Contemporary
Abstract Algebra,
**9th edition**. Make sure you get the 9th edition (blue 5-leaf clover on a black background), because otherwise your problem numbers won't match mine. Here are some good ways for getting the text for under $100:- You can rent the book in either hard copy or e-book form at chegg for about $30 per semester. Make sure your rental extends at least through the day of the final (Thu Dec 12), though. Also, note that chegg has a 14-day or 21-day return policy, which will be useful to those of you still deciding whether to take this class, and if you rent a hard copy, you get to use an e-book while waiting for your hard copy to arrive. In short, this seems like your best bet.
- You can do the same thing, but directly from the publisher. This actually seems a little cheaper, but doesn't seem to have the return policy.
- You can do the same thing at amazon, but they do this annoying thing where they have different prices for different people, so I can't predict if you'll get a better or worse price there. I also have no idea what their return policy is.

- Click here to go to our Canvas page, where you can submit PS outlines online (under the Assignments heading). You can also get to our Piazza discussion group from our Canvas page; click on the "Piazza" menu item on the left-hand side.
- Alternately, to get to our Piazza discussion group directly, just click on this link.
- Our weekly problem sessions will be held every
**Friday, 10:30am-noon**, somewhere on the 4th floor of MacQuarrie. - If you'd like to do some review/self-study on methods of proof, see this handout on writing proofs. You might also try looking at Reading, Writing, and Proving, by Daepp and Gorkin.

Course content: Axioms for groups and
rings, Cayley tables for
D_{6}.

Patterns for: D_{4} calculators
(squares), D_{5} calculators
(pentagons), D_{6} calculators
(hexagons).

Also, check out Gallian's website, with links to useful things like online flash cards for definitions (hard copy version).

- If you're interested in typesetting math, the system I use to
make my handouts is called LaTeX. If you have a Windows PC, you can
download LaTeX for free at http://www.miktex.org; you will also
need a good text editor, like the shareware program WinEdt. PCTeX also makes a good commercial
version; student prices are $150 for the "Publisher" version, which I
recommend if you have the money, $50 for the "Writer" version, which I
recommend if you don't. If you own a Mac, you can download a complete
system called TeXShop for free.
If you own a Linux computer, you already own a copy of this program,
as it's been a standard Unix program for about 20 years.
LaTeX is well worth learning, if you have some free time; it's used for manuals and technical reports throughout nerd-dom. For self-study, I highly recommend Learning LaTeX (Griffiths and Higham) for beginners, and the LaTeX book by Leslie Lamport as a reference.
