There are some minor differences between the two editions.

This course serves two main populations, students from mathematics and students from computer science. The course also has two distinct goals. One is to teach the basics of set theory, logic, combinatorics and graph theory. The other is to convey the rigorous use of terminology and proof which is essential to mathematics: that is, clarity and precision in definitions and statements of fact, and logical methods for establishing that a statement is true. The fundamental mathematics taught in this course is useful in computer science, 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, three midterms and a final exam. Some of the assignments will be done on Webwork . Other assignments will be handwritten. Written assignments should be done carefully and legibly. They will be graded and returned to you promptly (to the best of my ability).
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.
Point value for the work will be as follows (plus or minus 50 points)
