Course description

This book is all about exploring the secrets behind those special number grids where rows, columns, and diagonals add up to the same total. It begins with the basics—what these grids are and why they’re so interesting—and then dives into various methods for creating them. You’ll learn not only how to build these grids step by step but also discover the hidden math principles that make them work.

As you move further, the book introduces a twist: what if instead of adding numbers, we multiply them? This opens up a whole new layer of fun and shows how math concepts often come in pairs, like two sides of the same coin. Later sections tackle puzzles like filling in incomplete grids or even creating “anti-magic” grids where nothing matches!

Towards the end, the book takes a surprising turn by connecting these playful grids to a big idea in math called group theory—a topic usually considered advanced, but broken down here in a simple, intuitive way. Throughout, the writing is warm and encouraging, filled with examples, problems to try, and historical tidbits that make the content rich and relatable.
