## An Introduction to Discrete Mathematics, by Steven Roman |

*An Introduction to Discrete Mathematics, Second Edition* by Steven Roman is once again available, now from Innovative Textbooks. This text was the leading seller in earlier days before it got unceremoniously kicked from publisher to publisher, in some cases without the author's knowledge! Nevertheless, it is still a perfect text for a course in elementary discrete mathematics. (A permutation in 1995 is still a permutation today.)

Current price of the book is $99.00, plus $7.00 for priority mail shipping. Please allow 3-4 business days to receive your copy of the book. THIS IS FOR SHIPPING WITHIN THE UNITED STATES ONLY. For other locations, please send us an email with the shipping address to inquire about shipping costs.

Please note that the book is a spiral bound (so it will lay flat) photocopy of the Second Edition, published originally by HBJ. Any pages that contain color that is important for the exposition are copied in color. The remaining pages are black and white.

Please also note that WE DO NOT ACCEPT RETURNS. ALL SALES ARE FINAL.
