Discrete mathematics studies finite, countable, or otherwise discrete structures rather than continuously varying quantities.
Discrete mathematics is the study of mathematical structures that are separate, countable, or finite, rather than continuously varying. Its objects include integers, graphs, logical statements, sets, algorithms, and other structures that can often be enumerated using natural numbers. Although there is no single exact definition, the field is commonly associated with finite or countably infinite sets and contrasts with continuous mathematics, which includes real numbers, calculus, and classical Euclidean geometry. The scope of discrete mathematics is broad and includes logic, set theory, combinatorics, graph theory, number theory, algebraic structures, information theory, and theoretical computer science. It provides fundamental concepts for algorithms, programming languages, cryptography, databases, automated theorem proving, software verification, computer networks, and computational geometry. Discrete mathematics may also use techniques from continuous mathematics, and it has discrete counterparts such as discrete calculus, difference equations, discrete geometry, and discrete probability. Its importance expanded significantly with the development of digital computers, which process information in discrete steps and bits.
