Homework, tests, grading, and schedule

What's this course all about?

According to
http://www.math.ucdavis.edu/profiles/glossary.html,
number theory is “The study of properties of integers,
generalizations of integers, and relations between them, especially
Diophantine equations (equations in integers) and prime numbers.”
We will study modular arithmetic, divisibility theory (including the
Euclidean algorithm), prime factorization and the distribution of
primes, perfect numbers, and Fermat’s Last Theorem. The
course will involve writing LOTS of proofs. **The
only way to become better at understanding and creating proofs is to
do it – lots! **

How will class work?

We'll spend most class time seeing presentations and working on problems in small groups. When we come to the end of a topic, I will give a brief summary. Many problems on the midterm and final will come from presented problems, so everyone is responsible for all of the problems that get presented.

Resources

M*A*T*H Colloquium – You should make this a regular part of your week. Especially relevant to you this semester are the talks on March 16 and April 27.

**Other books**:

The library has several other Number Theory texts. You might find them useful for other reading.
