The origin of Arabic numerals.
Xiao Ming is a child who likes to ask questions. One day, he became interested in the numbers 0-9: why are they called "Arabic numerals"?
So, he went to ask his mother: "Since 0-9 is called 'Arabic numerals', it must have been invented by the Arabs, right, Mom?" ”
Mom shook her head and said, "Arabic numerals were actually invented by Indians. About 1,500 years ago, Indians used a special word for numbers, and these characters had 10 words, which could be written with just one or two strokes.
Later, these numbers were introduced to the Arabs, who found them simple and practical, and they were widely used in their own countries and then spread to Europe. And just like that, it slowly became the number we use today. Because the Arabs played a large role in disseminating these numbers, it was customary to call them 'Arabic numerals'.
Xiao Ming listened and said, "So that's the case. Mom, can this be called 'wrong is wrong'? Mom smiled.

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!

A short story of Chen Jingrun in mathematics.
Mathematician Chen Jingrun, while thinking about a problem, walked and hit the trunk of a tree without raising his head and said, "I'm sorry, I'm sorry." "Keep thinking.
A short story by the mathematician Rudolph.
In the 16th century, the German mathematician Rudolph spent his whole life calculating pi to 35 decimal places, which later generations called Rudolph's number, and after his death, others engraved this number on his tombstone.
A short story by mathematician Jacob Bernoulli.
After his death, the Swiss mathematician Jacob Bernoulli, who studied the spiral (known as the thread of life), was engraved on his tombstone with a logarithmic spiral, and the inscription reads: "Although I have changed, I am the same." It's a pun that both portrays the nature of the spiral and symbolizes his love for mathematics.

1.When he was a child, Hua Luogeng's family was poor, and he dropped out of school before graduating from junior high school. While he helped his father look after the store, he still didn't forget to study.
With no time, he developed the habit of waking up early, being good at using fragmentary time, and being good at mental arithmetic. There are no books, no paper and no pen, and he has developed the habit of being diligent in his hands and diligent in independent thinking.
2.When the mathematician Gauss was in high school, every night the teacher would give him one or two difficult problems for him to practice, but he could basically solve them quickly, but one day, the teacher gave a problem, and he used one night to make it, and then when he came to the school and asked the teacher, he learned that the problem was accidentally caught by the teacher, which is a mathematical problem in the world and has plagued mathematicians for more than 100 years.
Hua Luogeng (, was born in Jintan District, Changzhou, Jiangsu, and his ancestral home is Danyang, Jiangsu. He is a mathematician, academician of the Chinese Academy of Sciences, a foreign member of the National Academy of Sciences of the United States, an academician of the Third World Academy of Sciences, and an academician of the Bavarian Academy of Sciences of the Federal Republic of Germany. Member of the Standing Committee of the 1st to 6th National People's Congress of China.
He is the founder and pioneer of many aspects of Chinese analytic number theory, matrix geometry, canonical groups, automorphic function theory and multivariate complex function theory, and is listed as one of the 88 great mathematicians in the world today in the Chicago Museum of Science and Technology. The mathematical research achievements named after Fahrenheit in the world include "Fahrenheit's theorem", "Fahrenheit's inequality", "Fahrenheit method" and so on.

2.Or Gauss, in elementary school, in order to punish students, the teacher asked them to calculate 1 until 100, and when everyone else was desperately adding, Gauss quickly calculated it using the method that the number is equal to 101 at the beginning and the end.
3.Von Kármán, when he was a child, he was painting and playing on the ground, his father asked him how much 12x12 was equal in order to make things difficult for him, von Kármán gave the answer without thinking, and his father asked how much 33x56 was equal to, he still gave the answer without thinking, and finally his father asked how much 256x123 was equal to, and von Kármán only gave the answer after thinking about it slightly.

Gauss was late for class once, and by the time he arrived at the classroom, he had almost finished class. When Gauss walked into the classroom, he found that the teacher was not there, and there were several questions written on the blackboard. Gauss thought that these questions were today's homework questions, so he wrote them down.
That night, he spent the whole night working on these math problems, and what he didn't expect was that they were unusually difficult. Gauss solved only one problem until dawn, and the next day he went to his teacher in frustration and told him all about it.
His teacher was shocked: "These are the most famous problems in the history of mathematics, and you solved them in just one night?" The problem that Gauss solved was the problem of drawing a regular seventeen-sided ruler that had plagued mathematicians for 2,000 years.
That year, Gauss was only 19 years old!
Chen Jingrun is a famous mathematician in China. He doesn't like to go to the park, he doesn't like to walk the road, he loves to study. When he learned, he often forgot to eat and sleep.
At one point, he was thinking about his beloved math as he walked. Because he was too obsessed and focused, his body hit a telephone pole, and he didn't raise his head, and quickly said sorry, sorry.

Story: The Monkey Fishes the Hat.
A group of monkeys were playing by the well, a gust of wind blew a monkey's hat into the well, he beckoned 18 friends to come and fish for hats one by one from the pine above the well, there were 4 monkeys who did not go up the tree, so they fished the hats, and asked: How many monkeys went up the tree and down the well to catch the hats together?

Newton, because of an apple?
The great mathematician of the Northern and Southern Dynasties, Zu Chongzhi, calculated pi to the seventh decimal place. It is proved that pi is located between and . More than a thousand years before the Europeans got the same result.

The Pythagoreans of ancient Greece believed that any number in the world could be expressed as an integer or a fraction, and made this one of their creeds. One day, one of the members of this school, Hippasus, suddenly discovered that the diagonal of a square with a side length of 1 was a strange number, and he studied it diligently, and finally proved that it could not be represented by integers or fractions. But this broke the tenets of the Pythagoreans, and Pythagoras ordered him not to spread the word. >>>More
