• Printing Suggestions for Typed Files

I recommend two-page-to-a-side and/or double-sided printing to save paper. If the typed print is too small, try something like Page Setup: Scale: 110%, unless print gets cut off (100% may be better for handwritten notes). Color printing is nice, but B&W printing is cheaper.

These are pdf files. You can get the free Adobe Reader at http://www.adobe.com. Get a version that is compatible with your system!

• Textbooks / Resources

• Textbook I used: Rosen

(I later concluded that this text may be too advanced for the beginning discrete math student. It's great for a math or computer science professor, but it may not be clear for students. See OTHER BOOKS below.)

Discrete Mathematics and Its Applications (4th Edition)

by Kenneth H. Rosen. (WCB/McGraw Hill, 1999)

• Discrete Mathematics with Applications by Susanna S. Epp

This text is much clearer than Rosen's, though it doesn't have as many interesting problems. Maybe start with this book, and, if you love the stuff, try Rosen.

• Relax, Bill!

Fuzzy theory is wrong, wrong, and pernicious. What we need is more logical thinking, not less. The danger of fuzzy logic is that it will encourage the sort of imprecise fuzzy thinking that has brought us so much trouble. Fuzzy logic is the cocaine of science.
