MAT 108: Introduction to Abstract Mathematics (Fall 2018)

MAT 108: Introduction to Abstract Mathematics (Spring 2020)

Homework Assignments

Each assignment is due at 5pm. Turn them in on canvas. Use a scanner or smart phone app such as Adobe Scan to make a pdf file. Late homework will not be accepted. Solve the assigned problems in order. Assignments will be graded not only on correctness but also on the quality of writing; in particular, the reader is instructed to stop reading if a solution is incoherent.

In each section of the book, some problems are labeled by the star (*), which means that their answers are given in the back. For practice, do as many of these as you judge necessary. The problems listed below are those that you need to turn in (unless explicitly stated otherwise). If you are using an earlier edition of the book please make sure that you are working on the right problems.

Some solutions will be provided, but will not be carefully proofread, so check for mistakes!
