There is a monkey in the forest. They live in harmony. Good food is always shared equally by everyone and never mistreats either side.

Once, 20 monkeys picked 130 wild pears, but it was impossible to calculate how many pears each monkey should get. The monkeys were so busy for a long time that they couldn't eat pears at once. Some of them jumped around, scratching their heads.

The scene of monkeys sharing pears has long been clearly seen by a fox hiding outside. At this time, the fox swaggered towards the monkeys. "Monkey, what makes you so anxious?" Without waiting for the monkey to answer, the fox went on to say, "This is because the pears are unevenly distributed. This matter is easy to handle. Let me help, will you? "

"Great!" Several monkeys agreed without saying anything.

So the fox pretended to count in detail, then counted the monkeys and said, "Your 130 pears will be distributed to 20 monkey brothers." According to the formula'130 ÷ 20', every monkey brother should get ... "

As he spoke, the fox wrote the vertical score "",130÷20 on the ground and crossed out a 0 after 13, and crossed out a 0 after 2, which is easy to forget.

The monkeys looked at ""and nodded. A monkey scrambled to say, "We only have one pear each, and there are/kloc-0 pears left." The fox patted the monkey on the shoulder: "Dude is very smart. Now you all take six, and finally let me try the last one. "

"Wait!" At this time, a golden monkey jumped in front of the fox and pointed to the vertical division he wrote and said, "In the vertical division, a zero is crossed out, which means that they are reduced by 10 times at the same time, so the remainder is reduced by 10 times. In this way, the score you want is not 1, but 10. "

"It turns out that the fox is not kind enough to help!" The other monkeys understood at once.

(2) the fourth grade math fairy tales (the shorter the better)

There are three ancient trees, and their ages are composed of three different numbers: 1, 2, 3, 4, 5, 6, 7, 8 and 9. One tree is exactly half the age of the other two trees. How old are these three ancient trees? "

The lame fox said, "This question is very simple. However, if I help you figure it out, can you give me a hand? "

"No problem! Save people! " The little squirrel readily promised.

The fox said, "You use the smallest three of these nine numbers, 1, 2, 3, to form 123, and the largest three numbers to form 789, 123+789 = 9 12, which is exactly twice as much as 456. In other words, 456 is exactly 12. "

The little squirrel said happily, "These three ancient trees are 123 years old, 456 years old and 789 years old. How old are they! Take good care of these ancient trees. "

The king of the country ushered in an unprecedented battle-the dot invaded the digital kingdom! No matter how big it is, if you touch it, it will become someone else and defeat the enemy yourself.

④ 50 words of mathematical fairy tales.

Kittens, puppies and hedgehogs are playing games.

The kitten asked the puppy

How many thorns does a hedgehog have?

The puppy replied, the square root of y

The kitten was surprised. Is it the square or square root of y?

⑤ Mathematical fairy tales 100 word limit.

When Gauss was in elementary school, once after the teacher taught addition, because the teacher wanted to have a rest, he came up with a topic for students to calculate. The theme is:

1+2+3+ .....+97+98+99+ 100 = ?

The teacher is thinking, now the children must start class! I used this as an excuse to go out, but Gauss stopped me! ! It turns out that Gauss has worked it out. Little friend, do you know how he did it?

Gauss told everyone how he worked it out: add 1 to 100, and add 100 to 1, adding two lines, that is:

1+2+3+4+ .....+96+97+98+99+ 100

100+99+98+97+96+ .....+4+3+2+ 1

= 10 1+ 10 1+ 10 1+ .....+ 10 1+ 10 1+ 10 1+ 10 1

* * * There are one hundred sums 10 1, but the formula is repeated twice, so the answer is equal to < 5050 & gt.

Since then, the learning process of Gauss Elementary School has already surpassed other students, which laid the foundation for his future mathematics and made him a mathematical genius!

⑥ Mathematical fairy tales

In the mysterious kingdom of mathematics, fat "0" and thin "1" are two "secondary figures" who often argue endlessly about who is important. Look! Today, two small enemies met in a narrow way, and another war of words was launched between them.

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. "No matter how arrogant you are, you are insignificant. Look! 1+0' is not equal to myself. What's your use? "

"Let's 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' doesn't mean anything!"

"This shows that you have little knowledge." "0" said unhurriedly "You see, in daily life, the temperature is 0 degrees. 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 is impossible, such as 0. 1.

Seeing that the fat man "0" and the thin man "1" both blushed, no one would let anyone, and the other people watching were very anxious. At this time, "9" had a brainwave and made a pause gesture: "Don't argue, both of you. Look at you, which number is better than me,'1'and' 0'? " This ... "Fat man" 0 "and thin man" 1 "are 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.

⑦ A short mathematical fairy tale, about 50 words.

Too short to find, there is a mathematical fairy tale about life.

God replied, "Are you satisfied?" "ah! Lord, "the donkey replied," that's too long. Think about how hard I live! Carrying a heavy burden from morning till night, I dragged bags of millet into the workshop so that others could eat bread. All they know is to beat me and kick me to cheer me up. Please free me from this long and painful years. " God felt sorry for it, so he shortened its life span by eighteen, and the donkey went away with peace of mind.

Then the dog came again. "How long do you want to live?" God asked, "Thirty years is too long for a donkey, but you will be satisfied!" " "Lord," the dog replied, "is this your will? Think about how I will run. My feet will never last that long. When I can't scream, what can I do except run from corner to corner? "God thought it was right and shortened his life span by twelve years.

Then the monkey came. "You must want to live for thirty years?" God said to it, "You don't have to work like a donkey and a dog, but you can enjoy life." "ah! Lord, "it will answer," I always do something interesting, such as making faces to make people laugh. If they give me an apple to eat, I will take a big bite, but it is sour. Sadness is often hidden behind laughter! I can't stand it for thirty years. " God's mercy has reduced it by ten years.

Finally, human beings appeared. He is so happy, healthy and full of energy. He asked God to set his life span. "They all think that 30 years is too long," said God. "When I just built the house and lit a fire on my stove, when I was about to enjoy life, I was going to die! Oh, Lord, please prolong my life! " "Plus eighteen years of donkeys." God said. "This is not enough." The man replied. "Plus twelve years of dogs." "It's still too little." "Then," God said, "I will give you another ten years of monkeys, but no more." People finally left with satisfaction.

In this way, a person can live to be seventy years old, but as long as he can live the first thirty years like a person, he will work healthily, happily and happily at this stage. Next is the eighteenth year of the donkey. At this time, the burden of life is on the shoulders, and the quilt turns round and round, but it can't fall down. He had to work hard to support others, but his loyal service was rewarded by punching and kicking. Then came the dog's twelve years. He lost his teeth and couldn't bite anything. He could only lie on the wall and growl angrily. After this painful day, he entered a monkey-like life. At this time, he was stupid and confused, and became the object of teasing and ridicule by children.

Eight mathematical fairy tales

The lame fox stole the chicken and tried to hit it six times. The bear spat on his hand and said, "I am strong, let me fight!" " "

Bell stretched out his arm and punched the fox five times. The fox fell to the ground with a plop, and the bear hit him in the tree with his last punch. It took the fox a long time to catch his breath.

At this time, a little squirrel with a paper in his left hand and a pen in his right hand was walking on the branch and said, "Oh, this math problem is hard to die. How to do it! " "

The little squirrel suddenly looked up and was startled: "Oh, why is there a dead fox in the tree?"

The lame fox half-opened his eyes and said weakly, "You just died!" " "

"Is it alive?" The little squirrel was startled again.

The lame fox whispered, "Do you have a problem? Can I help? "

The little squirrel said, "You were hurt so badly that you helped me solve the problem. What a good fox! " The topic is this:

There are three ancient trees, and their ages are composed of three different numbers: 1, 2, 3, 4, 5, 6, 7, 8 and 9. One tree is exactly half the age of the other two trees. How old are these three ancient trees? "

The lame fox said, "This question is very simple. However, if I help you make it, can you give me a hand? "

"No problem! Save people! " The little squirrel readily promised.

The fox said, "You use the smallest three of these nine numbers, 1, 2, 3, to form 123, and the largest three numbers to form 789, 123+789 = 9 12, which is exactly twice as much as 456. In other words, 456 is exactly half of the sum of 123 and 789. "

The squirrel said happily, "The ages of these three ancient trees are123,456,789 respectively. How old are you! We must protect these ancient trees. "

The lame fox said, "I have worked out this problem for you." Please pull me up! " "

Little squirrels squeaked a few times, and some little squirrels came out of nowhere. Everyone shouted their songs and dragged the lame fox up. The little squirrel who helped disappeared in the blink of an eye.

The lame fox said to the squirrel, "I want to eat something, but I don't eat vegetarian food."

The little squirrel asked, "What do you want to eat?"

The lame fox said, "Chickens and mice have 49 100 legs to move forward. Please think about it. How many chickens and mice will come? " Dare not eat chicken, so we have to eat mice. "

The little squirrel asked, "How many mice do you want to eat?"

"Do the math!" Fox listed a formula: the number of rats is (100 -49×2)÷2= 1 (only).

The little squirrel asked in surprise, "Is this 1 mouse me?"

"It's your little squirrel!" The lame fox jumped forward with his mouth open.
