Introductory Discrete Mathematics (Dover Books on Computer Science)

I found this book to be extremely useful; last year I took basic courses in Linear Algebra and Calculus. The sections on Recurrence Relations and Graph Theory are particularly good, but I did struggle a little more with the bits on Generating Functions. The book is exceptionally clearly written, and my friend in Discrete Mathematics found it pretty useful for his exams. Highly recommended.

Clear and precise

The book contains too many ambiguities and shortcuts for an intro. The further you go into the books chapters, the worse it becomes. Many examples are impossible to understand without working out the steps between the assumptions and conclusions. Maybe good as quick reference for an up to date reader, definitely not an "Introduction"
