The animal school held a children's song competition, with the elephant teacher as the referee. The little monkey raised his hand first and began to recite: "I can calculate carry addition, and the digits can only be added if they are aligned." The number of digits should be aligned with the number of digits. When the number of digits exceeds ten, the number of digits should be advanced to ten. Add ten and one to count quickly and accurately. "
As soon as the little monkey finished speaking, the puppy began to recite again: "abdication and subtraction are not difficult, just align the numbers." If the single digits are small enough, ten people can borrow one. If ten people return, one will be ten, and if they return, one will be missing. How to reduce ten digits, ten digits will be reduced again and again. "
Everyone applauded their wonderful performance. Teacher Elephant said, "Their nursery rhymes make us understand that both carry addition and abdication subtraction should win the championship, ok?" Everyone agrees and applauds them.

Thales was a clever mathematician in ancient times. When he saw that people were reading the notice, he went to check it. The initial notice said that Pharaoh wanted the smartest person in the world to measure the height of the pyramid. So I went to Pharaoh. Pharaoh asked Thales what tools he used to measure the pyramids. Thales said he only used a stick and a ruler. He put the stick next to the pyramid. When the shadow of the stick was as long as the stick, he measured the length of the shadow of the pyramid and half the length of the bottom of the pyramid. Add these two lengths to get the height of the pyramid. Thales is really the smartest man in the world. He can easily measure the height of the pyramid without climbing to the top.

When Gauss was still in the second grade of primary school, one day his math teacher wanted to use class time to deal with some personal affairs, so he planned to give the students a difficult problem to practice. His topic is:1+2+3+4+5+6+7+8+9+10 =? Because addition has just been taught, the teacher thinks it will take a long time for students to solve this problem. I can also take this opportunity to deal with unfinished business. But in the blink of an eye, Gauss had stopped writing and sat there doing nothing. The teacher saw it and called Gauss angrily.

One day, mother rabbit took the little white rabbit to buy carrots. As soon as they entered the supermarket, they saw many goods arranged neatly. Where will the carrots be? They asked the shopping guide in the supermarket. The shopping guide said: "Our supermarket has 12 rows of goods, each with 4 rows, and the third row in the eighth row is carrots!" Mother rabbit asked the little white rabbit, "Count from line 1 and column 1 to line 8 and column 3. Can you take mom to find the carrot counter quickly? " The little white rabbit proudly said, "This can't beat me!" " We can find it like this. First, calculate the number of columns in front of the carrot counter by multiplication, and then add three columns to the eighth row to know where the carrots are. "The little white rabbit listed the formula" 7×4+3=3 1 (column) ",so the little white rabbit took his mother to the 3 1 column and found the carrot at once. When I arrived at the carrot counter, I saw that the price of carrots was 3 Qian Yuan Jin. Mother Rabbit tested the little white rabbit again: "We want to buy 12 Jin. How much do you want?" The little white rabbit said loudly, "this can't beat me!" "Multiply the unit price of carrots by the number of kilograms we want to buy, 3× 12=36 (yuan), and we need to pay 36 yuan money!" Mother rabbit happily touched the head of the little white rabbit and said, "Mathematical knowledge is really useful, and you are smart!" " "Son, you should also study math well!

Archimedes has many stories, the most important of which is the story of discovering Archimedes' principle in the bath. The king made a golden crown. He suspected that the craftsman had stolen some gold with silver, so he asked Archimedes to identify whether it was made of pure gold and not to damage the crown. Archimedes thought hard about the crown all day. One day, Archimedes went to the bathroom to take a bath. He went into the bath tub. When he immersed himself in the bath bucket, some water overflowed from the side of the bucket. Archimedes saw this phenomenon and crackled in his mind. "I found it!"
Archimedes put an equal weight gold nugget and a silver nugget into a container filled with water, and found that the silver nugget discharged much more water. So Archimedes took a gold nugget with the same weight as the crown and put it in a container filled with water to measure the displacement; Then put the crown in a container filled with water to see if the amount of water discharged is the same, and the problem will be solved. With further research, Archimedes principle, the most important cornerstone of fluid mechanics, was born.
