Features: Genius sets the problems, wise solves them. New trendy brain-training! Although there's a saying that "math has no practical use," most students with middle school education or higher would say that the math in textbooks and exam math has no practical value. On the other hand, enthusiasts of "math games" have begun to advocate treating math as a "source of enjoyment" and "pastime." Arithmetic calculations, factoring, equations, proofs of geometric figures, functions, and many other concepts have become examples of having no practical use, of course, with many more examples. In today's society, not only in daily life but also in almost all factories, enterprises, academic research fields, and other areas, due to various forms of information, math is either indispensable or at least unavoidable. Additionally, the subject of math itself has been advancing rapidly, and in this era, even professional mathematicians struggle to understand things outside their own field. Publishing this book in such a time aims to take a completely different perspective from "school math" (textbook math) and explore a broader range of content, "easily cultivating readers' mathematical intuition." It provides an in-depth yet accessible explanation of the importance of math in modern society in new research fields. Various fascinating questions are raised by two mischievous students, such as "Why can't you divide by 0?" "Why can division with fractions be reversed?" "Why does (-) × (-) result in ()?" and many others, which are answered by the professor in innovative and unique ways, sparking your enthusiasm for learning math. Through this book, you can learn to challenge and solve mathematical doubts. By approaching the subject from different angles and exploring broader content, you can easily develop your mathematical intuition, allowing you to naturally acquire a flexible mathematical mind. It can be said that it is a helpful tool to quickly boost your confidence in math. With a "wise eye" for math, even math problems you've never heard of or seen before can be solved effortlessly! Simple arithmetic problems like "multiplying an 8-digit number by a 1-digit number (12345679 × 9)" can be answered instantly, and issues like "the incredible relationship between car tires and pi" will be explained in the professor's relaxed and humorous discussions, helping you unravel your doubts and effortlessly enter the magical world of math. Does math have practical value in our daily lives? Why not check here? The professor will tell you how to think about problems with divergent thinking. Of course, "consciously using math" will also help you discover many interesting things in your daily life.
