Who put forward the mathematical composition?
The famous mathematician Hua is not only willing to work hard, but also good at thinking. When I was fourteen years old, once, the math teacher Wang Weike gave the students such a question in class: "I don't know today's number, 3322, 5522, 7722." What is the geometry of things? " This question comes from Shu Jing, a grandson in ancient times, which means: There is one thing whose quantity is unknown. If you count in twos and threes, there will be two in the end; Five, five places, and finally there are three left; Count to seven, and there are two left. Ask how many of these things are there?

As soon as Teacher Wang finished reading the questions, Hua blurted out, "Twenty-three!"

"Why, have you read The Art of War?" Teacher Wang asked in surprise.

Hua replied, "I don't know the book Sun Tzu's Art of War, let alone read it."

"Then how did you work it out?" Teacher Wang asked again.

Hua methodically replied: "I think so, three three-place numbers, more than two, seven seven-place numbers, more than two, and the rest are all two." Then, the total may be three times seven plus two, which equals twenty-three. When twenty-three is divided by five, the remainder is exactly three. Therefore, 23 is the number sought. "

"Ah-"Miss Wang was stunned. "What a coincidence!"

Mathematicians' Short Stories: (3)

1. Mathematician Gauss is in high school. Every night, the teacher will give him one or two difficult problems to practice, but he can basically solve them quickly. But one day, the teacher gave him a question, which took him one night to work out. Later, he came to the school to ask the teacher, only to know that the problem was accidentally caught by the teacher. This is a mathematical problem in the world, which once troubled mathematician 65438+.

2. Still Gaussian. In primary school, in order to punish students, teachers asked them to calculate 1 and add it to 100. When everyone else wanted to add it, Gauss worked it out quickly by using the method that the beginning and end homesickness were equal to 10 1.

3. Von Carmen painted on the ground for fun when he was a child. His father asked him what 12X 12 was, and von Carmen gave the answer without thinking. His father asked how much 33X56 was, but he gave the answer without thinking. Finally, his father was a little panicked and asked what 256X 123 was equal to. Von Kamen thought about it a little before giving it.
