Gaussian solution 1+2+3+4+. . . +100 story
Goss started school at the age of seven. /kloc-at the age of 0/0, he entered the class of learning mathematics, which was the first class established. Children have never heard of such a course as arithmetic before. The math teacher is Butner, who also played a certain role in the growth of Gauss.
One day, the teacher assigned a question, 1+2+3. ...................................................................................................................................................
Gauss quickly worked out the answer. At first, Gauss's teacher Butner didn't believe that Gauss had worked out the correct answer: "You must have miscalculated. Go back and do it again. " Gauss is determined, and the answer is 5050. The calculation method of Gaussian is as follows:1+100 =1,2+99 =10/kloc-0+51=/kloc-0. There are 50 groups of such numbers from 1 to 100, so 50X 10 1=5050.
Butner looked at him with new eyes. He specially bought Gauss the best arithmetic book from Hamburg and said, "You have surpassed me, and I have nothing to teach you." Then, Gauss and Bater's assistant Bater established a sincere friendship until Bater died. They studied together and helped each other, and Gauss began real mathematics research.
Data expansion:
Story: a literary genre that focuses on describing the development of events. It emphasizes the vividness and coherence of the plot and is more suitable for oral narration. What happened. Or imagine a story. Stories are generally closely related to the production and life of primitive humans. Primitive humans are eager to understand nature, so imagine that everything in the world has life and will be like people.
Some stories are a kind of memory behavior of human history, and people use various story forms. Memorize and spread the cultural traditions and values of a certain society and guide the formation of social character. By recalling and narrating the past, the story describes the cultural form of a certain range of society. It is also said that the story is not a style, but an event, which has a meaning through narration. He played a great role in studying the spread and distribution of culture in history.
Language is dynamic.
Stories don't need too many descriptions of psychological activities, long dialogues, complicated and delicate descriptions of scenery and characterization, and authors should not comment on the characters or events in the stories. The author should always pay attention to promoting the flow and progress of the story. Language is dynamic, and the characters in it will live without deliberate description.
Love stories mainly refer to love stories between men and women, which are recorded in the form of stories and published on the internet or magazines. Love articles are based on the description of love between men and women, exploring the meaning of love and describing the forms of love. You can use real events as the writing background, and you can also beautify love stories.

Math Story-Change
A customer of a sugarcane shop bought a new cane for 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 customer, caught him and said, "You liar, I paid 50 yuan, neighbor, and I gave you 20 yuan. You took a crutch, and you have to compensate me 100 yuan. "
The customer said, "The cost of a walking stick 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, how much will * * * cheat?

Monkey fishing hat
A group of monkeys are playing by the well. A gust of wind blew a monkey's hat into the well. He called 18' s friends and fished for his hats one by one from the pine trees by the well. Four monkeys don't climb trees, so they go for hats. Q: How many monkeys got their hats from the well under the tree?
The short stories of "0" and "1"
In the mysterious kingdom of mathematics, two "secondary numbers", namely "0" of the fat man and "1" of the thin man, often argue endlessly about who is important. Look! Today, these two little enemies meet in a narrow way, and they have launched another war of words. The thin man "1" spoke first: "Hum! Fat' 0', what's so great about you? Just like 100, what's the use of you two being fat without my thin'1'?" Fat man "0" is not convinced: "Don't be overbearing in front of me. Think about it. Without me, where can you find other figures to make up 100? " "hey!" "1" is not to be outdone. "If you are arrogant again, you are nothing. Look! 1+0' is not equal to myself. What's your use? ""go! The result of'1× 0' is not me, and your'1'is also useless! "'0' is tit for tat." You ... "1" paused and improvised. " Anyway, your' 0' is nothing! ""This is your lack of knowledge. " "0" said unhurriedly, "You see, in daily life, the temperature is 0 degrees. Is there no temperature? For another example, without my starting point on the ruler, how can there be'1'?" "No matter how you compare, you can only do the middle number or mantissa, such as 1037, 1307, and you can never lead." 1 "said confidently. Hearing this, "0" said more confidently: "This may be, for example, 0. 1, what can you do without my" 0 "to occupy it?" Seeing the fat man "0" and the thin man "1" all blushed, and no one would let anyone, and the other people watching were very anxious. At this time, "9" had a brainwave and made a gesture of pause: "Stop arguing, both of you. Look at you, which number is bigger than me? " "This ..." The fat man "0" and the thin man "1" were speechless. At this time, "9" said calmly: "1" and "0". In fact, as long as you stand together, aren't you older than me? "1" and "0" looked at each other, and it took a while to scratch their heads and laugh. "That's right! The power of unity is the most important thing! " "No.9 said seriously.
The little squirrel is going to spend the winter.
Winter is coming, and the little squirrel has to prepare food for the winter. One day, the little squirrel came to the forest with a big bag on his back and said to Grandpa Pine, Would you please give me your pine cone? Grandpa Pine was generous and said: Pick as many as you want. The little squirrel is very happy. He picked it up and sang. Soon the bag will be full. Grandpa Pine asked: How many did you pick? The little squirrel said, Oh, I forgot! Grandpa Pine smiled and said, "I planted 16 pinecones, and there are nine more. If you can figure out how much you picked, I'll let you carry it. " The little pine tree is in a hurry and can't be counted. What shall we do? If Grandpa Pine won't let him take it away, what will he eat in winter? I will help it. In math class, the teacher said: knowing the total number and finding the partial number is to remove the known partial number from the total number and get another partial number, which is calculated by subtraction. I soon figured it out that the little squirrel picked 16-9=7 (pieces).
The story of two generations of love
On this day, two generations of love came back from outside riding his beloved little donkey. He saw two people standing in front of his house, one tall and one short.
"Two generations of love are back!" The tall man and the short man can't wait to see him, so that Afandi can find a way to give them the five coppers. Afandi smiled and said, "Ah, gentlemen, I don't know what happened yet. How can I help you? " The two talked for a while, and the two generations of love made things clear. It turns out that these two people cook together today. The tall man took out 200 grams of rice, and the short man took out 300 grams of rice. The meal was ready, and they were about to eat it when suddenly a passer-by came over and asked them to let three people eat the cooked meal. As a result, the three of them finished eating together. Passers-by thanked the tall man and the short man when they left, and left five coppers for the meal. But how can I give five coppers to two people? The short man said that he took three coppers when he gave 300 grams of rice, and the tall man took two coppers when he gave 200 grams of rice. But the tall man said that the five coppers were given to them by passers-by, and they should be divided equally, and each person should take two and a half coppers. When two people figure it out, they don't know how to figure it out
Two generations of love told the tall man and the short man, "This is very simple. In my opinion, it should be divided like this. " The two generations talked about his division of labor: the tall man got 1 copper coin, and the short man got 4 copper coins. The two were very surprised. Later, after two generations told the truth about the split, they were persuaded and left happily.
Children, do you know why two generations of love are divided like this? It turned out to be like this:
Because five coppers are one person's meal and three people eat it, the meal for three people should be 15 coppers. This meal used 500 grams of rice, so the price of 100 grams of rice should be 3 copper coins. The tall man gave 200 grams of rice, which is six copper coins according to the money. When having dinner together, he has to deduct 5 coppers for the meal, so he only deserves 1 coppers. The short man gave 300 grams of rice, which is 9 copper coins by money. He also had dinner together, so he should deduct five coppers from the meal, so he should get four coppers.

Text:
Bears don't like the right to learn. He just wanted to do business, so he opened a fruit shop next to the school. Rabbit and monkey are his classmates. They have agreed to teach this lazy guy who doesn't like school. They came to bear's fruit shop.
"How much are the peaches?" Asked the little monkey. "The first basket is 6 yuan and 3 Jin, and the second basket is 6 yuan and 2 Jin." The bear replied. The little monkey said, "If I take 5 kilograms from two baskets, I will pay you 12 yuan, right?" The bear nodded.
"That I want it all. Since 5 kg is 12 yuan, then 60 kg is 12× 12= 144 yuan, right? " "Exactly, exactly." Said the bear. So the little monkey bought all the peaches, paid the money and left happily with the little rabbit. When I got home at night, the bear paid the bill and lost.
The next day, the little monkey and the little rabbit found the little bear and told him the situation. They smiled and said, "It's all because you don't study well that we came to teach you a lesson." They replenished the little money to the bear. Bear hung his head in shame, and since then, he has been very serious in class every day. The three of them became good friends.
(7) A speech about the short story of mathematics in life.
Everything in the world is doomed sometimes, and some can't be forced, so we can only accept it with a calm mind. This may be fate!
When the 2008 Olympic Games opened, my father and I went to Shanghai Gymnasium to watch the Olympic football match. The car passed through the bustling Shanghai and finally came to the gymnasium.
As soon as I entered the door, I saw many police uncles standing neatly in front of the stadium to maintain order. Dad asked me, "This path is about 200 meters long, and there is a policeman every 5 meters.". How many policemen are there on this road? " I said, "200÷5=40, and 40 police uncles stand in a * * *." Who knows dad said, "There are only 40 policemen on both sides of the road? Think again, is there any other situation to consider? " Oh, I understood at once. It turns out that I only counted the number of people on one side, not two. It should be (200÷5+ 1)×2=82.
We continued to walk inside and saw many people shopping for Olympic commemorative badges, key rings, puzzles and so on. We selected five Olympic commemorative key rings and two sets of puzzles. 5 yuan, a key ring, and 20 yuan, a set of puzzles. My dad took out a piece of 100 for my aunt to change. It happened that my aunt's calculator could not be found. My aunt and father asked me to calculate how much money I should get back. I picked up a pen and listed the formulas on the paper: 5×5=25 yuan, 2×20=40 yuan, 25+40=65 yuan, 100-65=35 yuan. It turns out that my father needs 65 yuan to buy these Olympic souvenirs, and my aunt needs 35 yuan. My aunt checked and made sure that my calculation was correct, and gave my father 35 yuan money. It seems that it is really important to learn to calculate correctly. If the calculation is wrong, don't give the wrong change!
Through what happened in Shanghai Stadium, I decided to study mathematics more seriously in the future, because life can't be separated from mathematics. Learning math well will make life colorful!
As a first-year math story, it is relatively simple and easy to recite.

Children's songs are simple in image, strong in rhythm and easy to remember. They are deeply loved by children and are the most easily understood and accepted literary forms by students. When the boring mathematical formulas and rules make students feel "tired of learning", they will compile the key points and difficulties in the teaching materials into nursery rhymes to make the mathematical knowledge "live". When learning the number 1- 10, it is difficult to write and remember. Therefore, children's songs are designed or used to help students remember.
1 Long and thin as a pencil, and floating on the water like a duckling.
Like ears listening to sounds, like red flags floating in the wind,
5 like a scale hook to buy food, 6 like a whistle tooting,
Like a sickle cutting grass, like a twist,
9 is like rice in a spoon, 10 is like ham and eggs.
In this way, students are catchy, vivid and easy to remember, and they also recall the life experience of kindergarten and have a happy memory.
When learning the position and direction, students are young and lack the concept of space, so I use familiar references to form nursery rhymes to help them remember.
Get up in the morning and face the sun. Think with your head.
The front is east, the back is west, the left is north and the right is south;
Reach out your right hand and remember the prisons in the southeast and northwest;
Specify the orientation of the map, with north at the top and south at the bottom;
Left is west, right is east, children should distinguish.
When learning the comparison of numbers, students begin to know the number ">"
