I have now written five math books, and may write another one in the following year. The current book includes new viewpoints about very well known numbers. Examples include pi and Euler's number.

There are also some theorems in the book, for example a theorem in geometry and the theorem which started it all. My. Precious. Journey.

In the book there are examinations of famous open problems like Riemann hypothesis and Collatz conjecture.

There are also some theories in the book as well. One example and also the best example is the tree generation and enumeration triplet. Such a beautiful design...
