Wu Jun's Lecture Notes on General Mathematics

How to see through the Ponzi scheme at a glance, manage money and invest well? How to make the best choice when buying a home loan? How to increase the chances of resume passing the preliminary screening? How to plan the company's development curve? More importantly, how to improve your cognitive level? How to change your way of thinking?

If you also pay attention to these issues and hope to use mathematical thinking to better improve yourself and understand the world, I hope you must read this book.

This is a general mathematics handout written for everyone. The book connects the entire mathematical system through key knowledge points and helps you gradually build your own mathematical knowledge structure. The history of mathematics development throughout the book is actually the history of the development of human cognition. You can use this to gradually train your cognition: from intuitive to abstract, from static to dynamic, from macro to micro, from random to deterministic to random .

For readers majoring in science and engineering, this book can help you better sort out previous mathematical knowledge, and look at mathematics and human knowledge systems from a higher level; for readers who are not majoring in science and engineering, it can better train Your own mathematical thinking allows you to directly attack the essence, simplify complexities, and make correct decisions.
