A relation in mathematics defines the relationship between two different sets of information. 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. | {{course.flashcardSetCount}} add a comment | 1 Answer Active Oldest Votes.

In the next example, we'll see how a mapping is used to create a list of ordered pairs. The set of x-values is called the domain, and the set of y-values is called the range. The important thing is for each x-value to be paired with the correct y-value. This defines an ordered relation between the students and their heights. Some values pair with more than one value, creating more than one ordered pair. The term "discrete mathematics" is therefore used in contrast with "continuous mathematics," which is the branch of mathematics dealing with objects that can vary smoothly (and which includes, for example, calculus).
