Interesting math story?

The following is a 300-word math anecdote. Let's walk into the auditorium of mathematics and let each character bring fun and convenience to our lives.

Chapter 1: 300-word interesting math story When Gauss was still in the second grade of primary school, one day his math teacher wanted to take time out of class 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.

But Gauss said he had figured out the answer, which was 55. The teacher was startled and asked how Gauss worked it out. Gauss replied:? I just found that the sum of 1 and 10 is the sum of1,2 and 9, 1 1, 3 and 8, 1 1, 4 and 7. And because11+1+11+11= 55, I worked it out like this. ? Hearing this, the teachers and students all gave Gauss a thumbs-up. Later Gauss grew up and became a great mathematician.

Chapter 2: Mathematical Fun Story 300 words Bajie went to Huaguoshan to find Wukong, and the Great Sage was not at home. The little monkeys treated Bajie warmly and picked 100 of the best peaches in the mountain. Bajie said happily. Everybody eat together! ? How to eat? Counting 30 monkeys, Bajie found a branch and drew it on the ground, and listed the formula. 100? 30=3? 1

The pig head pointed to the top three and said generously, Everyone eats three peaches. Look, the rest 1 I ate it! ? The little monkeys were very grateful to Bajie. They thanked him one by one, and then each took his share.

When Wukong came back, the little monkeys told Wukong how generous Bajie was today and why he only ate a peach. Wukong cried when he saw Pig's arrangement. What a fool! He ate too many peaches and kept his mouth shut. I'll find him! ?

Haha, do you know how many peaches Bajie ate?

Chapter III: Interesting Mathematical Story 300 words A customer of a crutch shop came and bought a crutch from 30 yuan. He took out a ticket for 50 yuan and asked for change.

Just as there was no change in the store, the shopkeeper went to the neighbor's house to change 50 yuan's ticket into change and gave the customer 20 yuan's change.

Just after the customer left, the neighbors came running in a panic and said that this ticket for 50 yuan was fake. The shopkeeper had to compensate his neighbor 50 yuan. Then I went out to chase the client, caught him and said, you liar. I gave it to my neighbor 50 yuan, I gave it to you 20 yuan, and you took a cane. You have to compensate me 100 yuan for the loss. ?

The customer said:? The price of crutches is 30 Yuan You left when your neighbor gave you change, so I only took your 70 yuan. ?

Please calculate, how much is the real loss of the rattan shop? It should be added here that the cost of crutches is 20 yuan. If this customer succeeds in fraud, how much did * * * cheat?

Chapter 4: 300-word interesting math story Today, I read a story called Swallow Tries Frog. The story goes like this: One day, the swallow said to the frog. Let's see who is better at math. The frog agreed. Frog problem: Last Monday, I ate a pest. On Tuesday, I ate three pests. After that, I ate two more pests every day than the day before. How many pests do I eat in a week? The swallow said,1+3 = 44+5 = 99+7 =16/6+9 = 2525+11= 3636+13 = 40.

The frog said, you test me. ? The swallow said, I ate two pests last Monday, four on Tuesday, and then I ate two more pests every day than the day before. Did I eat 56 pests a week? . Before the swallow finished speaking, the frog had given the answer. The swallow said, it's so fast! Can you teach me the trick of quick calculation? . The frog asked the swallow to draw seven circles, then put a pest in the first circle, and there were two more circles behind than in front. Their order is 1, 3, 5, 7, 9, 1 1, 13, which adds up to 49. The frog put a pest outside each circle and used it again. Swallows praise frogs for their cleverness.

A snail accidentally fell into a dry well, and it was crying at the bottom. A toad came up and said loudly to the snail. Don't cry, little brother. It's no use crying. The shaft wall is high and slippery, so you can only live here if you fall here. I have lived here for many years. ?

The snail looked at the old and ugly toad and thought, What a beautiful world outside the well! I can never live in a dark and cold well like it. ? The snail said to the toad. Uncle, I can't live here. I have to climb out. How deep is this well, hahaha? Just kidding, this well is 10 meter deep. You are so young. How can you climb out with such a heavy shell?

? I'm not afraid of hardship and fatigue. Climb for a while every day and you can always climb out! ? The next day, the snail was full and began to climb along the wall. It has been climbing up. At night, it finally climbed 5 meters. The snail was very happy and thought, at this rate, I can climb out tomorrow night. ?

Thinking about it, I fell asleep unconsciously. In the morning, the snail was awakened by a purr. When I saw it, it turned out that Uncle Tu was still sleeping, which was a big surprise. Why am I so close to the well bottom?

It turned out that this snail fell asleep and slipped down 4 meters from the well wall. The snail sighed, gritted his teeth and began to climb again. At night, it climbed up another 5 meters, but at night, the snail fell down another 4 meters. In this way, it climbed, climbed and slipped, and finally the strong snail climbed onto the well platform. Clever boy, can you guess how many days it took the snail to climb the drilling platform?
