Application: Widely used in the field of logistics. Finding the best purchase quantity of shopping malls is not a direct discrete problem, but also requires discrete thinking. In addition, where computers and numerical analysis are involved, discrete mathematics is essential. Discrete mathematics has more and more influence on human life.

Discrete mathematics is an important basic course for computer majors in universities of science and engineering. Not only for the following courses-data structure, operating system, compilation principle, database principle, artificial intelligence and so on. And it plays a unique role in cultivating students' innovative thinking, innovative ability and comprehensive quality.

Discrete mathematics is traditional logic.

Set theory (including function), number theory foundation, algorithm design, combinatorial analysis, discrete probability, relation theory, graph theory and tree, abstract algebra (including algebraic system, group, ring, field, etc. ), Boolean algebra, computational models (languages and automata) and so on. The application of discrete mathematics covers many fields of modern science and technology.
