Mathematics: A Discrete Introduction by Edward R. Scheinerman.
The textbook is mandatory.Topics we will cover
The main goal of the class is to teach how to do mathematical proofs, for this, one needs to know what a proof is. We will learn the importance of definitions, how to do proofs, many proof techniques and on the way we will use these techniques on different subjects of mathematics such as number theory, combinatorics, set theory and possibly graph theory too.Grading
The course grade will be based on:
Homework 25%,
Midterms 45% (15% each),
Final Exam 30%.
There will be written homework due roughly every week. The most recent homework will be posted in the announcements and a copy of all homeworks can be accessed here.
