3.2, Due Monday, January 23

The section for today was 3.2: Basic Properties of Rings.

I thought that the concept of "units" was kind of confusing. It would be helpful if you went over that in class.

I thought that the reading was pretty interesting. I liked the introduction, which reminded the readers that far more properties are used in Z than just the ring axioms. So naturally, there will be more properties that apply to rings in general.
