BRONX COMMUNITY COLLEGE

Of the City University of New York

DEPARTMENT OF MATHEMATICS AND COMPUTER SCIENCE

SYLLABUS: CSI30 DISCRETE MATHEMATICS 1         3 credits / 3 hours

PREREQUISITE: MTH 06 and ENG 02 and RDL 02 if required

TEXT: Discrete Mathematics and its Applications, Seventh Edition,

Goals of the course:

CSI 30 is an introduction to mathematical methods in computer science. It begins with basic concepts of mathematical logic, continues with an introduction to algorithms and programming, and concludes with an introduction to counting techniques and probability. The emphasis is on computational, hands-on experience. The material on set theory reinforces and complements parallel topics covered in Precalculus (MTH 30). It is highly recommended that MTH 30, if required, and CSI 30 are taken in the same semester.

Objectives: A successful student in this course will learn to:

1. 1.Understand the idea of an algorithm and computer program;

2. 2.Write and analyze simple programs;

3. 3.Understand the use of formal logic in mathematics and programming;

4. 4.Understand basic concepts of set theory, particularly those of a function;

5. 5.Use basic combinatorial counting techniques, particularly permutations and combinations;

6. 6.Understand basic concepts of probability theory, and the way counting techniques are used there.
