At this time, Hua knew that someone had come to buy cotton. When Hua sold cotton to a lady, he found that the toilet paper he used to calculate the problem was taken away by a lady. This made Hua desperate to catch up with the young lady, and he finally caught up with her. Hua said shyly, "aunt, please ... please give me back the toilet paper." The woman said angrily, "I paid for this, but." ...
Hua was in a hurry and said, "How about this! I paid for it. " When Hua reached for the money, the woman seemed to be moved by the child! He not only asked for money, but also returned the toilet paper to Hua. At this time, HuaCai slightly relieved. After returning home, I began to calculate math problems again.
2. Gaussian
Gauss's most famous story is to calculate the value of 1+2+3+ ... elementary school+100. At that time, Gauss was in primary school, and the teacher had such a problem in class, so let everyone calculate. The teacher thought it would take at least 20 minutes to get the answer, and just wanted to have a rest, but Gauss said that his ass had been worked out before he could sit still. The teacher was surprised and asked him how to calculate. He said that we should start with1+100 =101,and 2+99= 10 1. . . Such a * * * has 50 10 1, so the result is 5050.
There is another story. When Gauss 19 years old, he originally planned to study law. As a result, he inadvertently solved a math problem in 2000, that is, he only used a ruler and compasses to divide the circumference equally. Gauss also proved that if and only if n = 2 (2 n)+ 1, the circumference can be equally divided by a ruler n. Since then, Gauss's interest in mathematics has greatly increased, and he has embarked on the road of mathematical research and become a great mathematician.
3. Euler
Euler was born in 1707 in Basel, Switzerland. When he was a child, he liked mathematics very much. He began to teach himself algebra when he was below 10. Even several of his teachers haven't read the book, but little Euler read it with relish. When he meets something he doesn't understand, he marks it with a pen and then asks others for advice afterwards. /kloc-When he was 0/3 years old, he went to university of basel to study, which was a miracle at that time and once caused a sensation in mathematics.
Little Euler is the youngest student in this university and even in the whole Swiss university campus. In college, I got the careful guidance of johann bernoulli (1667- 1748), the most famous mathematician in calculus at that time, and gradually established a deep friendship with him.
Johann bernoulli later praised shine on you as better than the students in Lanzhou: "When I introduced Advanced Analysis, he was still a child, and you brought him up." Two years later, in the summer, Euler received a bachelor's degree from university of basel, and the following year, Euler received a master's degree in philosophy from university of basel. 1725, Euler began his mathematics career.
