**Learning Goals:**

Mastery of this course enhances the students' ability to construct and write proofs; to not only see beautiful ideas of number theory in the time of Gauss, but also reach some of those ideas themselves; and adds to their experience with algebra in general, in particular in association with the Math 150 modern algebra series.
