Math 311w - Concepts of Discrete Mathematics

Our final exam will be in 160 Willard on Dec. 14th from 2:30-4:30.


This is the web page for section 2 of Math 311w taught by Tim Reluga in the autumn of 2021.

This course introduces students to the use of mathematics as a formal language. Using a theorem-proof framework much like that used in Euclid’s geometry textbook millenia ago, we will study elementary number theory advances from ancient times to our current technological age. Theories of modular arithmetic, set theory, formal logic, groups, and other discrete-math topics will be covered, with applications to encryption and digital information encoding. The course will include several writing assignments to help students develop their communications skills.
