Discrete Mathematics provides an introduction
to logic and proof techniques, basics of set theory,
elementary number theory and cryptography,
combinatorial enumeration, discrete probability,
and graph theory, with a view towards applications.
It is designed for majors in mathematics, computer
science, statistics, and other related science and
engineering disciplines.
The purpose of this course is to understand
and use discrete structures that are
backbones of computer science. In particular,
this class is meant to introduce logic, proofs,
sets, relations, functions, counting, and
probability, with an emphasis on applications
in computer science.

There will be weekly homework assignments.
The assignments are due at the beginning of
the class on the day specified on the
assignment. In general, no extensions will be
granted.
What is Discrete Mathematics?
The study of discrete, mathematical objects and structures.
“Discrete”--Composed of distinct, separable parts. (Opposite of continuous.)
“Structures”--objects built up from simpler objects according to a definite pattern.
Discrete Structures We’ll Study

Why Study Discrete Math?
The basis of all of digital information processing: Discrete
manipulations of discrete structures represented in
memory.
It’s the basic language and conceptual foundation of all
of computer science.
Discrete concepts are also widely used throughout math,
science, engineering, economics, biology, etc., …
A generally useful tool for rational thought!
