Foundations of Real Analysis: Logic, Sets, and the Real Number System

Embarking on advanced mathematics requires a rock-solid grasp of the language of proofs, sets, and numbers. This text-based course guides you step-by-step through the core pillars of mathematical analysis. You will transition from computational arithmetic to rigorous mathematical thinking. By reading clear explanations and working through structured text exercises, you will develop the logical reasoning skills needed to understand and write formal proofs with confidence. What you'll learn: - Understand the principles of mathematical logic, truth tables, and quantifiers. - Apply basic set theory, functions, and relations to define mathematical structures. - Explore the properties of real numbers, including the completeness axiom, supremum, and infimum. - Practice constructing rigorous mathematical proofs using direct, contradiction, and induction methods. - Analyze the foundational concepts that underpin calculus and advanced mathematical analysis. The course begins with essential terminology, mathematical logic, and set theory before progressing to the rigorous definition and properties of the real number system. Each section features written explanations and practical exercises designed to solidify your theoretical understanding. This course is designed for beginners in mathematics, physics, engineering, or computer science who want to build a strong theoretical foundation without any prior advanced analysis experience.
