This is the first of two discrete math subjects for students of Computer Science at Wikiversity. The second course is called Discrete Mathematics for Computer Science. This page is tailored to provide you with introductory topics and problems in discrete mathematics. It is a prerequisite for Analysis of Algorithms, which is fundamental to any computing practices that require optimal performance in the face of limited resources.

Donald Knuth is a famous computer scientist and mathematician who has written numerous papers and a textbook on discrete mathematics.

Discrete mathematics is the part of mathematics devoted to the study of discrete (i.e. distinct) objects. In general, it is used whenever objects are counted, when relationships between finite (or countable) sets are studied, and when processes involving a finite number of steps are analyzed. It is important for computer science because in computing machines, information is stored and manipulated in a discrete fashion.
