Discrete Mathematical Structures – Bernard Kolman – 3rd Edition

For one- or two-term freshman/sophomore-level courses in Discrete Mathematics.

Combining a careful selection of topics with previews of their genuine applications in computer science, this text, more than any other book in its field, is written at an elementary level with a strong pedagogical focus. It limits its area and coverage of topics to those that students will actually utilize, and emphasizes both basic theory and applications, giving a firm foundation for more advanced courses, as well as providing an excellent reference work for those courses.
