I like math very much. As soon as I heard it was a math book, I couldn't wait to read it This book seems to have brought me into a world of mathematical fairy tales. Grandpa Li Yupei used fairy tales to make complicated mathematical knowledge easy to understand. Interesting fairy tales make boring operations have a soul and are no longer confusing. I learned some math knowledge from it, which can increase my interest in learning math well in the future.
The hero of this book is the cool monkey, who made an interesting trip to Africa with Hua Rabbit at the invitation of chimpanzees, gorillas and African lion kings. Cool monkeys fight these big animals in Africa. When disasters come, cool monkeys are not afraid of difficulties and overcome them one by one with mathematics. Because the cool monkey loves mathematics, he always saves the day with mathematics every time he encounters difficulties, so mathematics is a deadly weapon for the cool monkey. Chimpanzees and cool monkeys made a bet to let cool monkeys go around the forest. The cool monkey overcame all kinds of difficulties and came to the serpent. It turns out that the serpent was raised by a thin and bald man with red hair. They made a deal, and they won't let it go until they find out how many cobras, bungee snakes and pythons each of them has. Question: Each of them has 65,438+000 snakes, and each of them has three kinds of snakes. There are different numbers of cobras and bungee snakes. Then the cool monkey thought for a while and realized that the sum of three numbers is 100, and there must be an even number, and 2 is the only prime number in the even number, so each of them must have raised two pythons, two of which are not poisonous snakes, and the remaining 98 are poisonous snakes they raised. Then, 98 is divided by the sum of two prime numbers, and 98 = 65438+. 2、3 1、67; 2, 37, 6 1. So the three of them released the cool monkey and the flower rabbit. This shows that smart people are powerful and invincible.
After reading this book, I think there is such a mystery in mathematics. I will try my best to learn math well in the future.
At the invitation of chimpanzees, Cool Monkey and Flower Rabbit went to Africa to see who was the cleverest. They encountered many difficulties along the way and experienced many terrible things in Africa, but the cool monkeys skillfully solved the problem and resolved the danger. In order to eat fruit, I played games with baboons and got 30 fruits. Bravely fought chimpanzees and won. In order to find the big monster, they bravely broke through the pyramid, and all kinds of mathematical laws were discovered by the cool monkey ... The cool monkey is really a very clever monkey. It outsmarts chimpanzees, competes with gorillas known as monsters to find laws in mathematics, and helps the lion king of Mei Sen to protect his territory and overcome the infringement of the one-eyed lion king.
After reading:
Bwana devil is a book about interesting mathematics. Every short story written in this book contains a lot of knowledge about mathematics, which makes us unconsciously learn mathematics, analyze and solve problems while reading the story, and makes us fall in love with learning mathematics. Several times, I thought that the monkey did something wrong, but after analyzing with my mother, I found that the monkey's answer was correct, but my mother said that it was also a math exercise, because I also thought about the way the monkey did the problem when I was reading, and it was a way I liked very much. Cool monkey's mathematical knowledge is excellent and worth learning. I want to love and like mathematics as coolly as I do, and master all the calculations in my life skillfully. I will read more math books in the future, which not only increases the reading volume, but also improves my math ability. It's killing two birds with one stone!
