Permutations and Combinations for High School and Competitive Exams

Struggling to decide when to multiply, add, permute, or combine? Permutations and combinations form the bedrock of advanced algebra, probability, and competitive mathematics, yet they are often taught as confusing formulas rather than intuitive concepts. This written course demystifies counting theory, transforming abstract rules into logical, step-by-step problem-solving strategies. You will build a powerful mathematical foundation that prepares you for high school exams and competitive engineering entrance tests. By working through clear explanations and structured written exercises, you will transition from memorizing formulas to deeply understanding the logic of arrangements and selections. You will learn how to break down complex word problems, identify constraints, and apply the correct counting principles systematically. What you'll learn: - Understand the Fundamental Principle of Counting, including addition and multiplication rules - Master the mathematical theory behind permutations, combinations, and factorial notation - Solve arrangement problems involving identical items, repeated elements, and circular seating - Apply selection techniques to group formation, grid paths, and geometric configurations - Practice handling complex constraints, such as restricted positions and grouped items - Develop logical reasoning skills to approach non-routine algebraic problems systematically The course begins by establishing essential terminology and the core logic of counting before guiding you through structured written examples of increasing complexity. You will explore practical permutations, combinations, and advanced constraint-handling methods through detailed, text-based walkthroughs. This course is designed for high school students, pre-calculus learners, and competitive exam aspirants who want to master algebra from the ground up, with no advanced mathematical prerequisites required.
