# MATH 112 books

The usual book is very expensive,
so there's a different book that you can use instead.
You only need to buy *one* of these.
## The recommended book

- Title: Schaum's Outline of Discrete Mathematics
- Authors: Seymour Lipschutz and Marc Lipson
- Publishing data: McGraw-Hill, 2nd edition, 1997

This is not the usual book for the MATH 112 course,
but I've chosen it because it's quite cheap
and covers almost everything that we need in this course.
## The alternate book

- Title: Discrete Mathematics and its Applications
- Author: Kenneth H. Rosen
- Publishing data: McGraw-Hill, 4th edition, 1998

This book is the usual textbook for MATH 112,
and it will be the textbook for MATH 11 next term.
I'm not using it, because I think that it's far too expensive.
However, if it's worth it to you, this book also covers more material.
If you already have this book or decide that you want to buy it,
then you can use this book instead of Lipschutz & Lipson.
If you use this book, then be forewarned
that there are differences of terminology and notation
between this book and Lipschutz & Lipson.
## Supplementary handout

There is also a supplementary handout on rules of inference:
