Number Theory

These are notes on elementary number theory; that is, the part of number theory which does not involves methods from abstract algebra or complex variables.

The first link in each item is to a Web page; the second is to a PDF file. Use the PDF if you want to print it. There are videos for some of the sections, but they don't cover everything in the printed notes.

[July 15, 2019] These notes (but not necessarily the videos) were revised in Spring, 2019. I revised the sections on infinite continued fractions and periodic continued fractions after the term during May and June, and added a section on purely periodic continued fractions in July. I'm planning to add a section on continued fractions for radicals, and expand the section on the Fermat-Pell equation.
