Core Concepts in Algebra and Number Theory

Many technical fields require a solid understanding of mathematical structures and abstract reasoning, often found in foundational algebra and number theory. This course provides a clear, conceptual introduction to the essential topics, enabling you to confidently approach computational problems, understand cryptographic principles, and analyze mathematical systems. What you'll learn: * Understand the properties of sets, relations, functions, and fundamental algebraic structures like groups and rings. * Master integer arithmetic, divisibility rules, prime numbers, and the efficient Euclidean algorithm. * Apply modular arithmetic to solve congruence relations and grasp the basic principles used in modern cryptography. * Practice working with polynomial algebra, including identifying roots, factorization, and applying the division algorithm. * Analyze complex number systems and their geometric interpretations essential for engineering and physics applications. The material starts with rigorous definitions and axiomatic structures, progressing through classical number theory and abstract algebra concepts necessary for practical application. You will learn through detailed written explanations and step-by-step worked-out examples. This course is designed specifically for beginners and first-year university students in non-mathematical majors (such as engineering, computer science, or economics) who need a strong mathematical foundation. No prior advanced mathematical knowledge is required. Begin building your essential mathematical framework today.
