Set Theory and Boolean Logic: Foundations of Computer Science

Understanding how computers make decisions starts with mathematical logic and set theory. Whether you are preparing for high school computer science exams or wanting to write cleaner programming logic, mastering these core concepts is essential. This text-only course guides you through the fundamental building blocks of discrete mathematics, helping you transition from basic set operations to solving complex logical puzzles and simplifying Boolean expressions. What you'll learn: - Understand the core terminology of set theory, including subsets, unions, intersections, and complements. - Master fundamental logical operations such as conjunction, disjunction, negation, implication, and equivalence. - Construct and analyze truth tables to evaluate the validity of complex logical statements. - Apply Boolean algebra laws to simplify logical expressions and optimize conditional statements in code. - Translate real-world problems into formal logical representations and structured relations. - Explore how set theory principles apply directly to modern database queries and search engines. We begin with foundational definitions of sets and relations, progress to the laws of Boolean algebra, and conclude with practical applications in algorithm design. Through clear explanations and written practice scenarios, you will build a robust mental model of mathematical logic. This course is designed for high school students, introductory computer science learners, and aspiring programmers with no prior background in advanced mathematics.
