WHY STUDY DISCRETE MATHEMATICS? There are several important reasons for studying discrete mathemat - ics. First, through this course you can develop your mathematical maturity: that is, your ability to understand and create mathematical arguments. You will not get very far in your studies in the mathematical sciences without these skills. Second, discrete mathematics is the gateway to more advanced courses in all parts of the mathematical sciences. Discrete mathematics provides the mathematical foundations for many compu- ter science courses, including data structures, algorithms, database theory, automata theory, formal langu- ages, compiler theory, computer security, and operating systems. Students find these courses much more difficult when they have not had the appropriate mathematical foundations from discrete mathematics.

** Learning Outcomes:** On completion of Course, the student should:

- Understand the notion of mathematical thinking, mathematical proofs, and algorithmic thinking, and be able to apply them in problem solving.
- Be able to use effectively algebraic techniques to analyse basic discrete structures and algorithms.
- Understand some basic properties of graphs and related discrete structures, and be able to relate these to practical examples.
