49 Stories About Mathematical Formulas That Are Beautiful and Reasonable When You Know Them

Mathematical formulas can be beautiful? If this doesn't resonate with you, it's because you haven't yet encountered the true nature of mathematics.
Many middle and high school students are busy cramming complex mathematical formulas into their heads and memorizing them.
In order to do well in math tests and get the right answer, you just memorize the formulas.
However, you cannot build proper skills by just memorizing mathematical formulas without understanding them.
As the title suggests, “The Most Beautiful Mathematical Formula in the World” is a book that focuses on the beauty of mathematical formulas.
This book introduces the little-known beauty hidden in mathematical formulas in an easy and fun way, and is a popular textbook that shows a new side of mathematics to those who consider it complicated and difficult.


The authors of this book say that mathematical formulas are beautiful.
It explains that it comes from the flexibility of mathematical symbols, the simplicity of mathematical propositions, and the aesthetic appeal implied by mathematical symbols.
The authors select important formulas from the history of mathematics and those frequently encountered in middle and high school textbooks, and convey the joy of discovering the hidden meanings in formulas and symbolizing them through short texts and sensory illustrations.
49 short stories, beautifully illustrated to convey the text's content in an easily understandable way, lead readers to moments of insight into the fundamental formulas of mathematics.


Time to get one step closer to the world of mathematics
A youth education book that fosters the joy and courage of mathematics.

The authors of this book use real and fictional characters to explain in an interesting way why various mathematical formulas and concepts, such as square numbers, the Pythagorean theorem, solutions to quadratic equations, imaginary numbers, the surface area formula of a sphere, and trigonometric formulas, were created and what their meanings are.
Thanks to this, this book allows anyone with little prior knowledge of mathematics to experience the joy of mathematics with a lighter heart.
This book will be a particularly useful guide for students attending middle and high school.
If you read this book along with your math textbook before solving math problems, studying math will become much more fun.
I hope that this book will inspire readers to take a leisurely stroll through the world of mathematics, experience its beauty, and continue to explore new areas.
