MA357 — Elementary Number Theory, Spring 2020

Announcement, March 16:

Since the College has sent students home and instruction is to continue at a distance, I will be switching all this material to Moodle. Then I will start posting materials there for you to use.

One thing you can do now is check whether you can access this course's Moodle page. If you have problems, please email me as soon as you can.

This page contains course materials for MA357 and links to web sites that might be of interest.

I'll be adding more of these as the course progresses.

My home page.
Sage is free mathematical software. It can do algebra too. The easiest way to use it is the Sage Cell Server. It even works on mobile devices.
Pari-GP is less graphical, but (like Sage) it knows how to do lots of number-theoretical things.
Of course, there is also Wolfram|Alpha.
Wolfram MathWorld is more like an online encyclopedia of mathematics.
Another nice one is PlanetMath.
The hardest way to make a million dollars: the Clay Institute's Millennium Prize Problems. (One down, six to go.)
