A short story about multiplication Rush Rush !!!! shorter .

Early in the morning, the rooster crowed loudly, "Oh, oh." A little magpie was awakened and shouted unhappily: "It's so annoying who is screaming on such a cold day."

The magpie mother said, "Son, it's time to get up, the rooster is also good for everyone, tell us that it is dawn." In fact, his voice is not only beautiful and beautiful, but also contains some interesting mathematical knowledge!

The little magpie is very fond of mathematics, and when she hears her mother say this, she stops shouting. She listened carefully to the rooster's crow, and sure enough, it was regular, and she crowed happily: "I understand, I understand, the rooster crows 3 'oh' words each time, a total of 12 'oh' words, 4 3 = 12!"

So will I. So she made a series of funny noises, and the other animals who woke up in the morning praised the child for his ability. Children, what kind of multiplication equation can be written with the call of magpies, please give it a try!

Chirp, chirp, chirp, chirp, chirp.

The baby elephant was not convinced, and ran over with a bang, and also used his footsteps to make a multiplication problem.

Knock knock, knock knock.

After a while, the little pig came blowing a little trumpet.

Toot toot, toodoo, toodoo, tood.

After a while, all kinds of animals came to see the excitement.

The puppy said, "Who wouldn't bark and blow like this, and you have to draw the multiplication problem to be considered a skill!" ”

After saying that, he walked a few steps in the snow, and when he stopped, several footprints like plum blossoms appeared on the ground, and he said proudly: "Look, each plum blossom I painted has 6 petals, how many petals are there in 4 plum blossoms?" ”

10*10, add another egg behind 1 chopstick.

Multiplication is one of the simplest operations in arithmetic. The earliest multiplication of integers. What is Multiplication Multiplication refers to a number or quantity, increased by many times.

For example, 4 times 5 means that 4 increases the multiplier by 5, which can also be said to be 5 4 consecutive additions. The origin of "Little Ninety-Nine" "Ninety-Nine Multiplication Song" is also often called "Little Ninety-Nine". The "little ninety-nine" mantra that students learn now starts from "one by one gets one" and ends with "ninety-nine-eighty-one", but in ancient times, it was reversed, starting from "two-two-four" and ending with "ninety-nine-eighty-one".

Because the first two words of the formula are "ninety-nine", people refer to it as "ninety-nine". It wasn't until about the turn of the century that it was reversed, as it is now, "one by one......Ninety-nine-eighty-one". China used the "ninety-nine formula" earlier.

In books such as "Xunzi", "Guanzi", "Huainanzi", and "Warring States Policy", you can find sentences such as "three nine twenty-seven", "six eight forty-eight", "four eight thirty-two", "six six thirty-six" and so on. It can be seen that as early as the "Spring and Autumn Period" and "Warring States", "Ninety-Nine Multiplication Songs" has begun to become popular.

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

The teacher was thinking to herself, now the children must be counted as the end of class! I was about to excuse myself when I was about to excuse myself to go out, but I was stopped by Gauss!! It turns out that Gauss has already calculated, do you know how he calculated, kid?

There are 100 100 added up, but the equation is repeated twice, so dividing 10100 by 2 gives the answer equal to <5050>

Since then, Gauss's learning process in primary school has already surpassed other students, which has laid the foundation for his future mathematics and made him a math genius!

When Hua Luogeng was in middle school, in a math class, the teacher gave the students a famous problem: "There is a number, 3 3 numbers in 3 places, and there are 2 left; 5 5 land numbers, 3 remaining; 7 7 7 places, there are 2 left, what is the number of this? While everyone was thinking, Hua Luogeng stood up and said:

Once Chen Jingrun went to get a haircut, he was No. 38, and it was still early to get a haircut! So he went to the library and forgot about his haircut, and the number 38 was still in his pocket!

There was a crazy artist who, in search of inspiration, tore a very large piece of paper millimeter-thick in half, overlapping it, and then tearing it in half and overlapping it. Suppose he repeated the process like this, tearing it 25 times, how thick would this stack of paper be? Here are four answers, which do you think is closer?

a.As high as a mountain bAs tall as a tall buildingAs tall as a person d.As thick as a book.

The answer is: a. Because with each tear, the thickness of the stack doubles.

After tearing 25 times, the thickness of the paper is equivalent to 2 2 2 ......2 (25 2's multiplied), the thickness is about 3355 meters, which is equivalent to the height of a large mountain. Of course, this is only a hypothetical situation, and no one can tear a piece of paper like this.

Tang monks and apprentices walked on the boundless desert, they were hungry and tired, Zhu Bajie thought: How good it would be if there was a good meal! Sun Wukong is not as greedy as Bajie, Wukong just wants to drink a glass of water.

Sun Wukong thought about it, a family appeared in front of him, and there was a glass of milk on the table at the door, Sun Wukong hurriedly stepped forward, ready to drink this cup of milk, but the host said: "Great sage and slow, if you want to drink this cup of milk, you must answer a math problem correctly." Sun Wukong thought, isn't it just a math problem, it is difficult for my grandson.

Sun Wukong agreed. The host asked: Pour a glass of milk, you first drink 1 2 full of water, then drink 1 3, fill up with water, and finally drink all this drink, and ask which one you drink more milk or water?

Why? Sun Wukong looked at it, scratched his head, and after a while, it came out, and drank this cup of milk. Students, do you know the answer? Try.

Answer) Sun Wukong is very smart, because there is only one cup of milk, and every time he adds water, he knows that he only needs to calculate the total amount of water added. And the amount of water added is 1 2 + 1 3 = 5 6 (cups). So it should be more milk to drink.

Hua Luogeng is a master of modern mathematics plagiarism, too.

He is a man of learning. In the early 50s, the Chinese Academy of Sciences organized 16 famous scientists such as Qian Sanqiang, Zhao Jiuzhang and Hua Luogeng to go abroad. On the way, scientists talk about the past and the present.

Hua Luogeng took Qian Sanqiang as the title, and casually put out a couplet: Han Zhaowei, the top three, and consulted the next couplet. Everyone looked at each other, pondered and meditated, and could not be right.

Finally, Hua Luogeng pointed to Zhao Jiuzhang beside him and said: Chapter 9 Pythagorean strings. Hua Luogeng is familiar with the history of mathematics, and he has become a wonderful pair at his fingertips.

Su Buqing was born in September 1902 in Zhejiang Province. When I was in my third year of junior high school, a math teacher came. He said:

In today's world, the world's great powers want to carve up China. The danger of China's demise is imminent. In order to save the world, science must be revitalized.

Mathematics is the pioneer of science, and in order to develop science, it is necessary to learn mathematics well. At the age of 17, Su Buqing went to Japan to study. When he went to become an associate professor at a university in Japan, Su Buqing decided to return to China.

Zu Chongzhi is famous.

Count autonomics. It was the first time in the world to calculate the value of pi to be small.

The seven people after the number of Du were him. DAO pi is an infinite non-cyclic decimal number, Zu Chongzhi has studied that pi should be between and , and the age in which he lives is now 1500 years ago, and it is so accurate.

Riedrrich Yuan Gauss (born in Braunschweig and died in Göttingen) was a German mathematician, physicist and astronomer, geodesy. One of the founders of modern mathematics, he has a great influence in history, and can be ranked alongside Archimedes, Newton, and Euler, and is known as the "Prince of Mathematics".

-*****== Here's one of the stories about him ********************=

In a very short time, Gauss calculated the task assigned by the elementary school teacher: to sum the natural numbers from 1 to 100. The method he used was:

Sum 50 pairs of numbers constructed into a sum of 101 (1+100, 2+99, 3+98......).At the same time, the result is obtained: 5050. This year, Gauss was 9 years old.

The city's college entrance examination! It's pretty good, I highly recommend it.
