The main goal of this class is to introduce the students to basic mathematical
concepts used in number theory and techniques for their mathematical proof.
Your final grade is based on tests and homework presentations. You must
keep a neatly prepared looseleaf notebook of homework and be prepared to make
presentations in class.
