Discrete mathematics
Discrete mathematics is very broadly the area of mathematics that deals with discrete objects; that is, objects that can be enumerated. Another very broad description is that branches of mathematics considered discrete math are primarily concerned with sets, whereas branches of math known as analysis (such as calculus) are primarily concerned with functions. Some of discrete mathematics' many applications are in fields such as cryptography, linear programming, and coding theory.
