A chief wanted to give a piece of land to a beautiful goddess named Gitana. The size of this land can be enclosed by a squirrel skin. Guitana took the rat skin and didn't spread it directly on the ground. Instead, she cut it into very fine bumps and connected them into a long leather rope. She leaned against the coast with this leather rope and enclosed a large semicircle of land. As a result, she was assigned to a large piece of land and was assassinated by a clever chief. It turned out that a certain length of rope was used to enclose an area, and the area of the circle enclosed was the largest. Second, if it is surrounded by a complete circle, its area is indeed limited. Guitana uses the coastline as the diameter of this semicircle, which surrounds most of the land.
After reading this story, I realized that you can't just look at the surface of things. Sometimes a little thing can create great achievements if it is used properly. This story also tells us that we should consider things from many angles. If we don't think about them carefully, the conclusion is only one-sided and not necessarily the best.
Chapter two: Reflections on extracurricular reading of mathematics.
The smallest natural number, which is not positive or negative, is multiplied or divided by any number, and the result is equal to 0, with no reciprocal. who is it? Yes, this number is 0.
Recently, I read an interesting math story called 0 and its digital brother. The main idea of the story is as follows: 1234567890 Ten brothers went to the forest, and nine proudly thought they were the largest. Everyone agrees that 0 is the smallest, and every number has its own skills except 0, so no one plays 0. However, the elephant fell into the big hole and couldn't climb out. 1 to 9/came to help, forming the largest number, 98765432 1. No matter how hard you try, you can't save the elephant. Finally, 0 also came to help, forming 98765432 10, which expanded the strength by 10 times at once and rescued the elephant.
After reading this story, I have a deep understanding. It turns out that a small .0 can also release such great power! So, can't it be compared with small zero? The answer is definitelyno. Why do some people ignore a "0" when they are so bad at math? As long as you spend more time than others, listen carefully in class and finish your homework, you will make progress little by little. Remember, math is not learned by watching, but by thinking with your head. Math is very simple.
We must not look down on ourselves, nor be arrogant like 9, but learn with an open mind. No matter what happens, everyone should unite. As long as Qi Xin works together, we can overcome the difficulties. Since God has given talents, let it work! .
Chapter three: Mathematics commanders' thoughts after reading.
Today, I read the book Math Commander, mainly about a boy named Niu Niu, who is very good at math. He won the first prize in a math contest and changed himself to "Math Commander". The Kingdom of July 7th invited Niu Niu to attend an important meeting of the Kingdom of July 7th. In order to recapture their own territory, the July 7th Kingdom launched a war against the August 8th Kingdom, and Niu Niu became the real commander in chief of mathematics.
At the beginning, he outflanked and defeated the 88 kingdom, and the 88 kingdom sent mechanical beasts, all of which defeated the 88 kingdom. Xiao Qi's adjutant designed to arrest Niu Niu, but Niu Niu used his mathematical knowledge to escape and fabricated a reconnaissance to find out all the details of the 88 Kingdom. Niu Niu trained a circular queue and defeated the 88 Kingdom.
After reading this book, I know the importance of mathematics. I admire Niu Niu very much. There is one problem-there are seven soldiers, and the number of one is one. Let Niu Niu stand anywhere in the line and count them to see who can make it to the end, and then reward a bag of candy. Niu Niu stood in the eighth place and finally won. After watching this clip, I admire Niu Niu, the commander-in-chief of mathematics. I am attracted by the charm of mathematics, which can make people smarter. I also want to learn from Niu Niu, learn math well, and make myself smarter and more confident.
