First of all, this is a good book. This book is very readable and interesting, and can be used as the most introductory teaching material. I think mathematics and programming are two very important things, and this book can be used as a basic reading for these two subjects. Perhaps for your level, you have completely disdained this level of content. But this is your next generation. Next generation. Think about the influence of this book on those beginners. This book introduces the basic mathematics knowledge related to programming. This book introduces the basic mathematics knowledge related to programming. Say it twice because it's important. For those who have a good foundation in mathematics, there are naturally classic works such as Concrete Mathematics, Introduction to Algorithms and TAOCP waiting for you. Besides, this book is not that profound. I have basically lost interest in mathematics since I met a math problem in high school. When reading this book, I feel very good, interesting and easy to understand, and the content is really what programmers should know. Personally, I feel that the unsolvable problems in the book are very important and the most difficult part to understand. I didn't have a clear understanding of insolubility until I knew Turing's downtime. I think there are still many people like me. This chapter tells programmers that there are insoluble problems in the world, and there are boundaries that mathematics and programs can't reach. There is another sentence in this book that touched me ... it was moved. So please recommend some interesting and uncomplicated mathematical data, preferably related to programming or statistics ~ ~
