### Access your Grades

Please check your grades weekly on canvas. I will try to keep them up to date every week. Please check them for correctness and alert me to any errors.

### Textbook

**Official Text:***An Illustrated Theory of Numbers*, Martin H. Weissman.- Textbook Website
- The text will soon be on reserve in Gemmill Library, at which time I will post a link here

- Another nice book is A Friendly Introduction to Number Theory, by Joseph H. Silverman.

### Computing Resources

**Campus Computer Labs**– Use Sage (via link below), Latex, Maple, Mathematica, Matlab etc.- Search by software – e.g. tex, mathematica

**Latex**– the only reasonable way to type math.- Introduction to Latex – installing and how to type.
- Detexify – To find a symbol you want to know.
- Overleaf.Com – No need to install software or visit the lab – typeset online!
- Templates: tex file and expected output.
- Tex Stackexchange – question and answer service from the hive mind

**Wolfram Alpha**– Simple math computation without learning a syntax.**Sage**– Free, sophisticated math software for indepth exploration.- CU Sage Server – available with identikey.
- Ask Sage – question and answer service from the hive mind
- Sage’s Quick Reference Sheets to keep by your side.
- My own Mini Sage Introduction is one of many Sage tools on my cryptography class site.

### General Math Resources

Note: the internet can in fact do your homework for you in many cases. So can your friends, your mother, and your tutor. That’s not the point. Study (and drink) responsibly.

**Study Math by Speaking It****Tips on Doing Homework****Tips on Reading your Textbook**- Dr. Math – Question answer service (by ‘Math Doctors’). Use the search box first; there’s a 99% chance someone has asked your question before.
- Mathematics at StackExchange – Question answer service (by the ‘hive mind’). Use the search box first; there’s a 98% chance someone has asked your question before.
- Math Forum Digital Library – Catalogue of web resources.

### CU Resources

- The
**Undergraduate Mathematics Resource Center**is in Math 175 (first floor of math building).**Although tutors do not serve this course**, an area has been set up where you can meet your peers to work together. There are tutors that know number theory (Erik M 3-4, Th 11-1, F 11-12; Sebastian WF 2-4; Leo M 10-11; Jun W 5-6; Rob Th 9-10).

- A tutor list is available.
