Discrete mathematics is the study of mathematical structures that are fundamentally discrete rather than continuous.In contrast to real numbers that have the property of varying "smoothly", the objects studied in discrete mathematics – such as integers, graphs, and statements in logic – do not vary smoothly in this way, but have distinct, separated values. For this reason, it is important to have a table, mapping or graph available. Cantor developed the concept of the set during his study of the trigonometric series, which is now known as the limit point or the derived set operator. Chapter 9 Relations in Discrete Mathematics 1.
