Features: After reading this book, you might ask: Does this book cover all the shortcut methods? At this point, please remember that knowledge is endless. As long as you understand the principles, you can create many new methods on your own. Also, when you are reading this book, if you encounter anything you don’t understand, I hope you think deeply, discuss more with your classmates, and ask your teachers and parents. When learning each shortcut method, you might find it a bit troublesome, and it might seem faster to calculate step by step using the usual method. At this point, please remember the two lines of poetry from the ancients: "To see a thousand miles, climb one more story." Every time you overcome a learning challenge, you will gain infinite joy. When you first learn a shortcut method, you may not calculate quickly, and you might even make mistakes. At this point, please remember the saying "Practice makes perfect." You are not yet proficient, so you need to do more practice and find exercises for yourself anytime, anywhere. Each section of this book has exercises, and the answers are provided at the end of the book.
