This book is very practical! It introduces many quick calculation methods, such as quick calculation of addition and subtraction, clear multiplication, etc., Which is very helpful to improve calculation ability. Moreover, the author also innovated some methods, such as the scissor product and the plum blossom product of multiplication, which are very interesting.

It can achieve a certain effect, but I feel that if I memorize all the formulas in the early stage, I will forget the professional things I learned before, such as the Pythagorean theorem. If I suddenly think about it, I will make a mess, and it will feel like memorizing the text.
