● Preface

So that people who have difficulties like me can study a little faster and with less difficulty.
The theory contains only the essentials, and the problem-solving includes memorization tips and easy solution methods that I personally organized.
It's okay if you don't quite understand the theory.
Please read the first reading along with the commentary.
If you do that, at some point you will find yourself able to solve things on your own.
