### Announcements

[13 Nov 2017] Here are two handouts: one on

polynomials, and one on

change of bases. The polynomial one is from a previous course, and they
did not do ideals, but other than that it is pretty good.
The second prelim is a take home exam, and will be handed out in class,
on Tuesday, November 14, and will be due the following Tuesday, in class.
Rules for this will be posted, and discussed in class.

[8 Nov 2017] The last problem on the homework (on determinants) is now due on Tuesday, Nov 14. Also
several typos in that problem have been fixed!

[2 Nov 2017] The second prelim is a take home exam, and will be handed out in class,
on Tuesday, November 14, and will be due the following Tuesday, in class.
Rules for this will be posted, and discussed in class.

[12 Oct 2017]

Solutions to the first prelim. Stats: mean 62.8, median 63, standard deviation 14.9.

[3 Oct 2017] Stillman will have one more office hour this week, Wed 4-5 pm (in his office).

[3 Oct 2017] Here are some
solutions(

first
and

second) to the two practice
prelims. Some solutions given in the second practice
prelim are a bit too brief, in particular, problems 1(a), and 3(a).
But they contain the main ideas there, at least. I would prefer to
see a bit more detail for 1(a).

[3 Oct 2017] Here is the

"scratch" set of pages I will hand out in the prelim. They include the definition of a field and a vector space.

[28 Sep 2017] Here are two practice prelims (

first and

second) from previous semesters. On Tuesday, Oct 3, we will
discuss these, and do a general review as well. In some cases, the notation is a bit different than
what we are using, and we haven't done the isomorphism theorems yet (one problem asks about that). But mostly,
these are reasonable problems. Of course, they don't cover everything, but hopefully they are representative
in terms of difficulty. I am not sure that answers will be provided. That needs to be determined yet.

[5 Sep 2017] Office hours for Stillman: Tuesdays, 3-5. Office hours for Abby: Wednesday 2-4.

[16 Aug 2017] Welcome! The first class meeting is Tuesday, Aug 22, at 11:40 am, in room Malott 207.
