Welcome to the inaugural Series: “The Perfect Math Tutor for All”. The First math workbook is an exploration into the world of linear functions & equations and their real-life practical applications. Having spent over twenty-three years as a mathematics and calculus teacher in Canada, I’ve often encountered a recurring question from students: “What is the use of x or y in our daily lives, anyway?” One student poignantly remarked, “x and y will never bring me food to my table!” Now, almost nine years into retirement, I find joy in dedicating time to crafting math workbooks. This initial venture focuses on a specific mathematical concept, offering an introduction to its properties and delving into real-life applications. I aim to underline the significance of mathematics by embedding scenarios drawn from our everyday experiences, urging students not only to solve equations but to become creators, applying their newfound knowledge. Solving basic linear equations for x and y without real-world context renders the exercise futile. Variables like x, y, or z are not mere symbols but representations of unknowns, discovered through navigating diverse situations and solving practical problems. In the forthcoming workbooks, students are challenged to take total ownership of their learning process. I won’t task you with solving equations for x and y at the end, that’s not the purpose of these workbooks. While practice is valuable, it is insufficient if we cannot apply our knowledge effectively in our daily lives.
