Why do you study math?
A story for everyone who wants to become familiar with mathematics.

How many people in South Korea love math? If you were to look for people who enjoy math and do it as a hobby, you'd probably find only a handful.
Most people study math for a variety of purposes, such as for school exams, for employment, or to use it at work.
As a result, there will be many people who only have an aversion to mathematics without having time to think about the fundamental reason why they should study mathematics.
But "Mathematics" tells us that mathematics is fascinating and enjoyable in its own right.
Through time travel, readers delve into the lives of mathematicians who have made great achievements in history, conversing with them and living with them, and become closer to mathematics without even realizing it.
When you realize that mathematics is not just a discipline, but a way to view the world, a belief system, and a tool to help you live better in real life, whether in economics, agriculture, or architecture, you will see mathematics differently.

Following the era of Pythagoras and Euclid in Volume 1, Volume 2 moves into the era of Liu Hui, the greatest mathematician of the Three Kingdoms period in China, and Hypatia, a female mathematician of ancient Greece.
In the era of Liu Hui, it is fun to read about the background and atmosphere of the Three Kingdoms period in China, and you will be surprised by the fact that Eastern mathematics was of such a high standard.
Moreover, in Hypatia's time, you will feel the pure faith and passion for mathematics through the life of a female mathematician who fought a lonely battle in the strict social, religious, and political atmosphere of the time.

The math content incorporated into the story may be something you've seen in middle and high school workbooks, but there may also be something you're seeing for the first time.
But it doesn't matter if you don't understand all the mathematical concepts in this book.
The reason why the author of the book talks about 'mathematics' in the form of a 'novel' that anyone can easily read and become immersed in is not because he wants to convey mathematical knowledge, but because he wants to introduce the inherent joy of mathematics to more people.
