This book introduces the mathematics that supports advanced computer
programming and the analysis of algorithms.
The primary aim of its well-known authors is to provide
a solid and relevant base of mathematical skills\dash---the skills
needed to solve complex problems, to evaluate horrendous sums, and to
discover subtle patterns in data. It is an indispensible text and
reference not only for computer scientists\dash---the authors themselves
rely heavily on it!\dash---but for serious users of mathematics in
virtually every discipline.
Concrete mathematics is a blending of {\sc con}tinuous and dis{\sc crete}
mathematics. ``More concretely,'' the authors explain, ``it is the
controlled manipulation of mathematical formulas, using a collection
of techniques for solving problems.'' The subject matter is primarily an
expansion of the Mathematical Preliminaries section in Knuth's
classic {\sl Art of Computer Programming}, but the style of presentation
is more leisurely, and individual topics are covered
more deeply. Several new topics have been added, and the most significant
ideas have been traced to their historical roots. The
book includes more than 500 exercises, divided into six categories.
Complete answers are provided for all exercises, except research problems,
making the book particularly valuable for self-study.

This second edition includes important new material about mechanical
summation. In response to the widespread use of the first edition as a
reference book, the bibliography and index have also been expanded, and
additional nontrivial improvements can be found on almost every page.
Readers will appreciate the informal style of {\sl Concrete Mathematics}.
Particularly enjoyable are the marginal graffiti contributed by
students who have taken courses based on this material. Graham, Knuth,
and Patashnik want to convey not only the importance of the techniques
presented, but some of the fun in learning and using them.
