Course description
This course serves as a basic introduction to abstract algebra--groups, rings, and fields.   We will also give a brief introduction to writing mathematical proofs.  Proof are an important part of this course.  Highlights of the course may include: the fundamental theorems of arithmetic and algebra, the RSA encryption method, counting the number of different ways to color the faces of a cube with a fixed number of colors, the classical angle trisection problem, and John Stillwell's recent proof of Abel's theorem. If you ever wondered why you never learned a formula like the quadratic formula for higher degree polynomials, I think you will enjoy this course.

Linear algebra.  Math 290 or Math 291.  This course can be one of the more difficult undergraduate courses.  Experience with proofs is an asset.
