Math
103a is the first quarter of a two-quarter sequence in abstract algebra. The
main topic of this quarter is the theory of groups, emphasizing examples and
applications. No previous knowledge
of abstract algebra will be assumed, but students will be expected to be able
to understand and write basic proofs, as covered in Math 109. Despite the fact that
abstract algebra (either Math 103ab or Math 100ab) is a required sequence for
most math majors, we will definitely attempt to have
fun!

**Final Exam!** Monday, March 19 (next Monday!), 11:30 am – 2:30 pm in
Peterson 103. You may bring one 8 ½ by
11 sheet of paper written both sides.
The final will cover up to and including Chapter 10 of the text.
