Foundational Number Systems and Arithmetic

Do you struggle with the basic rules governing numbers and arithmetic operations? A solid understanding of the number system is the bedrock of all mathematical competence. This course provides a comprehensive, text-based introduction to the fundamental structure of numbers. You will learn to classify number types, apply core arithmetic properties, and utilize efficient methods for calculations involving factors, multiples, and exponents. What you'll learn: * Understand the definitions and properties of major number sets: natural, integers, rational, irrational, and real numbers. * Master the rules of arithmetic operations, including the commutative, associative, and distributive properties. * Practice applying modern divisibility rules and prime factorization techniques to solve complex problems efficiently. * Learn to calculate Greatest Common Divisor (GCD) and Least Common Multiple (LCM) using prime factorization and the Euclidean algorithm. * Apply concepts of exponents, roots, and basic modular arithmetic to simplify numerical expressions. The course begins with foundational definitions and number classification, progressing through arithmetic properties and rules of operation. We conclude with practical techniques for factorization, finding common divisors, and working with basic exponents. This course is designed for absolute beginners or anyone needing to refresh their core mathematical knowledge. No prior mathematical knowledge beyond basic counting is required.
