Introduction to Discrete Mathematics

Discrete Mathematics is a branch of mathematics dealing with structures that are fundamentally discrete rather than continuous. It involves mathematical objects that can only take distinct, separated values, such as integers, graphs, and statements in logic. The design purpose of discrete mathematics is to provide tools and techniques for solving problems in computer science, cryptography, combinatorics, and more. For example, discrete mathematics is crucial in algorithm design, where the efficiency and correctness of algorithms are analyzed using concepts like Big-O notation and combinatorial structures. Another scenario is in network theory, where graph theory, a major area of discrete mathematics, is used to model and analyze networks such as social networks, communication networks, and transportation systems.
