内容简介：
Discrete mathematics, also known as finite mathematics and combinatorial mathematics, has become an essential subject in computer science and mathematics. Using a deliberately informal exposition, often with examples from everyday life presented in a humorous fashion, the book covers all the necessary topics for beginners, including graph theory, algorithms, recursion, induction, number theory, probability, Markov chains, and game theory. Emphasis is placed on number theory and probability as well as computer science. Algorithms are introduced fairly early and exercises are included throughout.
