A set of nodes interconnected by lines to represent graphs, another section showing Venn diagrams, and a third section illustrating binary sequences.

## Introduction

Discrete Mathematics is a branch of mathematics that deals with objects that can assume only distinct, separated values. It is fundamentally different from continuous mathematics, which deals with objects that can vary smoothly. Discrete Mathematics has applications in computer science, information theory, and many other fields.

## Core Topics in Discrete Mathematics

### Graph Theory

Graph theory deals with graphs, which are structures used to model pairwise relations between objects.

### Set Theory

This area explores the concept of a 'set', which is a collection of unique objects considered as an object in its own right.

### Boolean Algebra

This involves algebraic structures that capture the essence of logical operations and relations.
