Course Textbook

I am writing a textbook on elementary number theory, so the textbook for this class is free. The book itself is under contract to publish with Springer-Verlag, so if you find any typos, no matter how minor, please tell me.

There are many other books on elementary number theory, and I encourage you to consult them.
