New York: Gordon and Breach, 1969. Discrete mathematics is the study of mathematical structures that can be considered "discrete" (in a way analogous to discrete variables, having a bijection with the set of natural numbers) rather than "continuous" (analogously to continuous functions).Objects studied in discrete mathematics include integers, graphs, and statements in logic.
