The class meets in Watkins 1101
on Monday through Thursday afternoons from 1:00 to 2:30.
My office hours will be in Surge 263,
on Monday mornings from 10:30 to 12:00
and on Tuesday, Wednesday, and Thursday afternoons from 3:00 to 4:30.
You can also meet with me by appointment.
This web site will be updated from time to time, so if you want information that's most up to date, then be sure to check back here again. Any important changes will be in the announcements, so at least check there. Of course, I'll also announce things in class.

The course also appears on UCR's Blackboard site. I will use that site for three things:

- Sending announcements to you by email;
- Maintaining a discussion board; and
- Keeping track of your grades (under Student Tools).

If your email address on Blackboard (which is also listed under Student Tools) is missing or wrong, then you won't get announcements by email, but they'll still show up on both that site and this site. Note that the Blackboard site requires Javascript to work.

Discrete mathematics is also called "Finite Mathematics"; in fact, that's the official title for this course. I believe that this name is meant to refer to the absence of calculus's infinite limit processes. But don't assume that all of the mathematical objects that we'll be dealing with are finite. In particular, we will cover recursion, a concept which inherently contains a potential infinity.

There is more information about the books.

There is also a supplementary handout on Rules of Inference.

- divisibility, congruences, and counting;
- sets, relations, and functions;
- graphs and trees;
- logic and proof; and
- induction, recursion, and recurrence relations.

Project lists will be handed out each week;
**the projects are due one week after they are handed out**.
The projects will also be posted online.

Numerically, I will grade harshly -- it's hard to get 100% on any assignment. On the other hand, the correspondence between numerical grades and letter grades is nicer than most math courses:

- [100%, ∞): A+
- [93%, 100%): A
- [86%, 93%): A-
- [79%, 86%): B+
- [71%, 79%): B
- [64%, 71%): B-
- [57%, 64%): C+
- [50%, 57%): C
- [43%, 50%): C-
- [36%, 43%): D+
- [29%, 36%): D
- [21%, 29%): D-
- [0, 21%): F

Here, "[*x*%, *y*%)"
means "[at least *x*% but less than *y*%]".
There is no rounding; an average of 49.99% is not enough for a C.

There will be 4 projects worth 10% each (40% in total), daily homework assignments worth 20% in total, and 1 examination worth 40%.

And here is the actual Final Exam itself:

- PlanetMath, a free encyclopaedia of mathematics written by mathematicians;
- MathWorld, an encyclopaedia of mathematics written by astrophysicist Eric Weisstein;
- Wikipedia, a free encyclopaedia of everything written by anybody that shows up, which has good coverage of many mathematics topics.
