1, Mathematical Story-Change

A customer of a crutch shop bought a crutch made in 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 the ticket for 50 yuan 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? I would like to add here that the cost of crutches is 20 yuan. If this customer succeeds, how much will * * * cheat?

2. Story: The monkey catches the 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?

3. Story: When did the snail climb the well?

A snail accidentally fell into a dry well, and it lay down at the bottom of the well and began to cry. A toad came over and said angrily to the snail, "Stop crying, little brother, it's no use crying. This 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 toad, I can't live here. I have to climb out. How deep is this well? " "Ha ha ha ..... it's a joke, this well 10 meters deep, you are so young. How can such a heavy shell climb out? " "I am not afraid of suffering, not afraid of being tired. I can always climb out after a while every day! " 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. At first glance, it turned out that Uncle Tu was still sleeping. He was surprised: "Why am I so close to the bottom of the well?" 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?

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.

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?

"Three" math stories are the shortest.

1. In 46 BC, Julius Caesar, commander-in-chief of Rome, specified the calendar. Because he was born in July, in order to show his greatness, he decided to change July to "Julian month", and all single months were stipulated as 3 1 day, and bimonthly was 30 days. In this way, there is one more day in a year. February was the month when prisoners were executed in ancient Rome. In order to reduce the number of people executed, 1 day was reduced in February to 29 days.

Augustus, Caesar's heir, was born in August. Following Caesar's practice, he added 1 day as "August", changed 10 and1February to 3 1 day, and changed September 1 1 month to 30 days. There are 1 day in the whole year, and he has reduced 1 day since February, so February has become 28 days, and there are only 29 days in leap years.

In this way, there will be a big month in a single month before July, and a big month in two months after July, February 28.

More than 300 years ago, a British mathematician first used the multiplication symbol "×". Because multiplication is a special addition, he marked the plus sign obliquely.

It is said that as early as 4,000 to 5,000 years ago, our ancestors used a drip instrument to measure time. This instrument is called lettering.

"Tangram" is a kind of ancient tangram in China, which is made up of seven pieces into a big square with various patterns. Later, it spread abroad and was called "Tangtu". "Tangram" has spread to today and become a kind of intellectual toy that people like.

The symbols "+"and "-"were first used by a German 500 years ago. At that time, they didn't mean "plus" or "minus". It was not until more than 300 years ago that it was officially used to mean "addition" and "subtraction".

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 are you going to find other numbers 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 other people watching were very anxious. At this time, "9" had a brainwave and made a gesture of pause: "You two stop arguing. 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 long time 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.

What is Wu's three-minute math story? I'm going to give a speech tomorrow.

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 inner 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.

"Lu" is a math story of grade one.

Xiaoming bought eight apples and gave them to Xiaohong No.2 and Xiaogang No.3. How many apples does Xiaoming have left?

The short story of the first grade math story competition in Qi primary school should not be too long or too short. . . . . . Because I'm afraid my sister can't recite it. . . . . .

Writing ideas: Math stories are easy to understand, and children usually like animal stories.

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.
