Introduction to the mathematics that supports advanced computer programming and the analysis of algorithms. An indispensable text and reference not only for computer scientists  the authors themselves rely heavily upon it  but for serious users of mathematics in virtually every discipline. Based on the course Concrete Mathematics taught by Knuth at Stanford University from 19701989. The second edition includes important new material about the revolutionary GosperZeilberger algorithm for mechanical summation. Complete answers are provided for more than 500 exercises.
It is to be hoped that this book succeeds in convincing many educators, not only in computer science but also in mathematics, that courses like this pay off!  J. H. Van Lint, International Reviews on Education (1990)
It is always a pleasure to look again into this book full of carefully explained and enthusiastically presented mathematics.  Volker Strehl, Mathematical Reviews (1997)
This is one of those books you keep forever, purely for its utility.  Naomi Novik, review on amazon.com (2010)

For a list of corrections to known errors in the pre1998 printings of the second edition, you may download the 19941997 errata file in compressed PostScript format (74K bytes). This file was generated by the TeX file errata97.tex in directory ftp.cs.stanford.edu:pub/concretemath.errata.old using special macros and fonts found in that directory. Errata lists for various printings of the first edition can also be found there. See also the list of errors corrected between January 1998 and May 2013, which is in HTML format.
And here is a list of all nits that have been picked so far since the 27th printing (May 2013). An asterisk (*) marks significant technical errors that are not merely typographical:
 page 8, line 8
 change 'only two regions per line' to 'only two regions per bent line'
 page 77, line 2
 change 'a real number' to 'a positive real number'
 page 87, display on lines 810
 change '$k<n$' to '$k<a^2$' under the first $\sum$; and append ', integer $a$' at the end of the formula.
 pages 107 (bottom) and 108 (top)
 change 'Suppose there were only finitely many ... None of the' to: 'Consider any finite set of primes, say $\{P_1,P_2,\ldots,P_k\}$. Then, said Euclid, we should think about the number
$$M=P_1\cdot P_2\cdot\ldots\cdot P_k+1.$$
None of the' page 108, line 7 (in the 27th printing only)
 change 'primes numbers' to 'prime numbers'
 page 192, lines 2 and 3 from the bottom
 change 'rule (5.45)' to 'rule (5.44)', and change 'way:' to 'way using (5.40):'
 page 288, line 4
 change 'sum of $n$th powers' to 'sum of $m$th powers'
With these corrections, the authors hope that the book is now errorfree. But (sigh) it probably isn't. Therefore Knuth will gratefully deposit 0x$1.00 ($2.56) to the account of the first person who finds and reports anything that remains technically, historically, typographically, or politically incorrect. Please send suggested corrections to knuthbug@cs.stanford.edu, or send snail mail to
Prof. D. Knuth
Computer Science Department
Gates Building 4B
Stanford University
Stanford, CA 943059045 USA.
In either case please include your postal address, so that I can mail an official certificate of deposit as a token of thanks for any improvements to which you have contributed.
DO NOT SEND EMAIL TO KNUTHBUG EXCEPT TO REPORT ERRORS IN BOOKS! And if you do report an error via email, please do not include attachments of any kind; your message should be readable on brandX operating systems for all values of X.
SPECIAL NOTE TO THE SPEAKERS OF FRENCH AND OTHER EXOTIC LANGUAGES: Numerous quotations and bibliographic citations found in this book have been copied verbatim from the original sources. If you believe you have found a typographic error, you must prove it by showing that the original was incorrectly transcribed; believe it or not, your language has changed over the years, just as English has.
Midterm and final exams from the last two times Knuth taught this course at Stanford (1988 and 1989) are now available, together with the answers, as compressed PostScript files. The teaching assistants who helped to prepare these exams were Sheralyn Listgarten and Sridhar Raman (1988); Alan Hu and Robert Kennedy (1989).
