Set Theory: Foundations of Discrete Mathematics

Set theory is the bedrock of modern mathematics, providing the essential language and framework for fields like computer science, logic, and statistics. This course provides a rigorous, text-based introduction to set theory, moving systematically from basic notation to complex operations, allowing you to confidently tackle rigorous problem-solving and formal proofs. Upon completion, you will possess a robust understanding of how mathematical structures are defined and manipulated. What you'll learn: * Understand the core concepts of sets, elements, and various set notations (roster, set-builder). * Master fundamental set operations including union, intersection, difference, and complement. * Apply De Morgan's Laws and other algebraic properties to simplify complex set expressions. * Practice calculating the cardinality of sets using the principle of inclusion-exclusion for counting problems. * Configure Cartesian products and define binary relations between sets using ordered pairs. * Analyze how set theory concepts map directly to foundational principles of Boolean logic and discrete structures. The course begins with fundamental terminology and notation, systematically progresses through set types and operations using clear written definitions, and concludes with advanced concepts like cardinality and relations, supported by numerous written examples and practice problems. This course is designed for absolute beginners in higher mathematics or those needing a rigorous refresher before tackling discrete math, logic, or competitive examinations; no prior mathematical knowledge beyond basic arithmetic is required.
