Discrete mathematics is the mathematics dealing with objects that can assume only distinct, separated values. It can often be characterized by integers, continuous objects require real numbers. Other fields of mathematics that are considered part of discrete mathematics include graph theory and the theory of computation. Topics in number theory such as congruences and recurrence relations are also considered part of discrete mathematics. Discrete mathematics is the mathematical language of computer science, and as such, its importance has increased dramatically in recent decades. This course is essential for students, particularly for those preparing for future computer science courses and research.
