About this course

Solving logical and mathematical word problems requires more than just basic arithmetic—it requires structuring your code so it is readable, reusable, and easy to maintain. This text-based course guides you through using Ruby to model real-world scenarios, such as calculating the average ages of teachers and students, using clean programming paradigms. You will transform word problems into structured, executable code while mastering core programming concepts. By completing this course, you will understand how to break down complex age-related word problems, represent real-world entities as code, and write clean Object-Oriented programs in Ruby. What you'll learn: - Understand foundational object-oriented concepts like classes, objects, and state management in Ruby - Apply inheritance to share common attributes and behaviors between teachers and students - Implement custom methods to perform calculations, such as finding averages and age differences - Structure clean, readable Ruby code using modern syntax conventions and type hints where appropriate - Practice debugging logic errors in mathematical calculations through written code exercises This course begins with core definitions and the fundamentals of Object-Oriented Programming in Ruby. You will then progress through step-by-step written walkthroughs that show you how to model entities, set up inheritance structures, and implement calculation logic. This course is designed for beginner programmers, students, and educators who want to learn how to apply basic programming concepts to solve logical math problems. No prior Ruby experience is required. Start reading today to build your problem-solving skills with Ruby.
