**Course background:
**This course is designed as an introduction to some of the
fundamental concepts that are at the intersection of Abstract Algebra and Number Theory.
As organized disciplines of investigation Number Theory is the older one of the
two. To a large extent Abstract Algebra arose from the realization that certain
structures that occur in the investigation of numbers occur in many other
important contexts, and that it is more efficient to investigate these
structures themselves and then apply the findings to the contexts in which these
structures arise, rather than

**Course objectives:**

1. Increase the sophistication of the student's skill in using elementary
materials in clever ways to create mathematics,

2. Enrich the student's mathematical culture by attention to historical context,

3. Prime the student's professional etiquette by giving attention to proper
written presentation, exposition and attribution of mathematical work,

4. Inspire the student's taste for searching for aesthetically pleasing
mathematics,

5. Develop the student's expertise in the mathematical method.
