Introduction to Set Theory and Modern Logic

Set theory is the foundational language of modern mathematics and computer science, shaping how we organize data, write database queries, and build logical arguments. Understanding how to group and manipulate collections of objects is essential for anyone entering technical fields. This course guides you from the absolute basics of sets to practical applications in logic and data structures. You will develop a strong mathematical mindset, enabling you to read formal notation confidently and apply set operations to real-world problem-solving. What you'll learn: - Understand foundational definitions, notation, and the core axioms of set theory - Perform essential set operations including unions, intersections, differences, and complements - Map relations and functions to analyze connections between different data groups - Apply set theory concepts to modern database queries, SQL joins, and programming data structures - Practice logical reasoning by solving structured word problems and mathematical proofs - Explore cardinality to measure and compare sizes of infinite and finite sets The journey begins with key terminology and basic notation before moving step-by-step into complex relations, functions, and practical applications in computer science. This text-only course is designed for absolute beginners, aspiring programmers, data analysts, and math enthusiasts with no prior advanced mathematical background.
