Foundations of Discrete Mathematics: Sets, Relations, and Functions

Every major field in computing—from database design to artificial intelligence—relies on the logical foundations of discrete mathematics. Understanding these core concepts is the first step toward writing efficient code, structuring data correctly, and thinking like a computer scientist. This text-based course guides you through the fundamental pillars of discrete mathematics: sets, relations, and functions. You will transition from basic mathematical definitions to understanding how these concepts shape modern data structures and software algorithms. What you'll learn: - Understand the core principles of set theory, including operations, subsets, and Venn diagrams - Analyze relations and their properties, such as equivalence, transitivity, and reflexivity - Define functions, mapping types, composition, and their direct applications in programming - Connect mathematical sets to modern data structures like hash sets, dictionaries, and databases - Apply logical reasoning to solve structured computational and mathematical problems You will begin with basic definitions and notation before progressing to written exercises that reinforce how these mathematical structures operate in real-world logic. This course is designed for aspiring software engineers, computer science students, and curious beginners, requiring no advanced mathematical background.
