Foundations of Whole Numbers and Number Theory

Building a strong foundation in mathematics starts with a deep understanding of how numbers work. This course guides you through the fundamental principles of whole numbers and number theory, helping you develop numerical fluency and logical reasoning. You will transition from basic counting concepts to analyzing patterns, divisibility, and prime factorization. By the end of this course, you will confidently solve arithmetic problems, identify number properties, and apply these foundational concepts to more advanced mathematical topics. What you will learn: Understand the properties of whole numbers including closure, commutativity, and associativity; Master divisibility rules to quickly analyze and break down large numbers; Find the Greatest Common Divisor (GCD) and Least Common Multiple (LCM) using multiple methods; Explore prime and composite numbers, prime factorization, and basic number theory; Practice solving practical word problems using structured step-by-step arithmetic. This course begins with essential terminology and foundational definitions before moving into structured, text-based lessons that build your skills systematically. It is designed specifically for beginners, students preparing for early algebra, or anyone looking to rebuild their mathematical confidence from the ground up, with no prior advanced math required.
