Math 105 - Math In Society​ - Hybrid Course

This course was last taught in Spring Term, 2019! For the online course, log into D2L.


Watch the Hybrid Course Information Video to the right.
Free textbook: Math in Society (Low-cost optional print copies $18 at the bookstore) + Section D1 and Section D3. Here is a draft of the PCC version of the Voting Methods Section.
Some content will be in D2L and online homework will be in MyOpenMath

Hybrid Class: Make sure this is the right format for you! The hybrid class is 40% in class and 60% online so we will only meet once a week and you need to have more self-motivation and responsibility. Tthe guideline is 13 hours per week outside of class. People vary so you may need more or less time. You will be watching video lectures outside of class and there is a class prep due on the first day. We will spend our limited class time working on the hardest problems together in groups.
