Olejar Books

This introduction to discrete mathematics is aimed primarily at undergraduates in mathematics and computer science at the freshmen and sophomore levels. The text has a distinctly applied orientation and begins with a survey of number systems and elementary set theory. Additional chapters treat: data structures, counting, probability, relations and functions, graph theory, matrices, number theory and cryptography.Good examples occur throughout and there are problem sets with selected solutions at the end of each section. A college algebra course is the only prerequisite.
