## Discrete Mathematics: Math 245, Spring 2012 Assignments

There are two types of homework assignments. Webwork assignments involve short answers, many of which (but not all!) are fairly routine. The problems listed in the first table below are more challenging. The problems from the 3rd edition are the same, or nearly the same as the ones listed from the 2nd edition.
Your solutions should be eminently legible, clearly written and carefully argued! Write your solutions so that one of your fellow classmates would be able to read and understand them.

The second table below lists other exercises in the textbook that are relevant to the course. I don't expect you to do all the problems listed, but it is worth reading many of them and solving a few of each type.
