This course serves three main degree programs: mathematics computer science, and computer engineering. The course also has two distinct goals. One is to develop skills in several areas of discrete mathematics: set theory, logic, number theory and combinatorics. The other is to convey the rigorous use of terminology and proof which is essential to mathematics: clarity and precision in definitions and statements of fact, and logical methods for establishing that a statement is true. The mathematics taught in this course is useful in computer science and electrical engineering. The analytical skills developed are critical to understanding computer languages, to the development of good programming skills, and, more generally, to appreciating scientific method. The experience with abstract concepts, proof writing and the use of formal definitions should help students in all disciplines to articulate their ideas more clearly.

We will have weekly assignments using Webwork , midterms and quizes and a final exam.
Point value for the work will be as follows.| Assignments | 150 |
| Tests | 550 |
| Final | 300 |
| Total | 1000 |
The point values for each item are subject to change by plus or minus 50 points.
The ranges for grades are as follows: 85% and above for A- and A; 72-85% for B- to B+, 60-72% for C- to C+ and 50-60% for D- to D+.
Most students find this a tough class. You will greatly magnify your chances of succeeding if you work regularly and attentively! Start the assignments early and do most of the exercises in each section we cover. If you get stuck, please ask me in class. Your questions often lead to a valuable class discussion. You are also quite welcome during my office hours, but come prepared.
