One day, when the digital cards were having lunch together, the youngest one spoke.

Brother 0 said, "Let's take some photos together. What do you think? "

0' s brothers and sisters said in unison, "Good."

Brother 8 said, "Brother 0' s idea is really good. I will be a good person once. Shall I provide camera and film for Brother 8? "

Old 4 said, "Brother 8, it's good, but it's a little too much trouble. Better use my digital camera. That's settled. "

So, they got busy. Finally, they took pictures for them and immediately sent the digital camera to the print shop. The computer sister tried to ask them for money, but who paid for it? They stared at each other one after another. This is what the computer sister said, "A ***5 yuan, a * * * eleven brothers and sisters, how much does one person pay on average?"

Among the eleven of them, Lao Liu is the cleverest, and this time he is the first to work out the result. Do you know how it is worked out?

2. The story of Gauss, a mathematical genius, as a child

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!

3. Europe is 0

About 1500 years ago, European mathematicians did not know how to use "0". They use Roman numerals. Roman numerals are symbols representing numbers, which are combined to represent different numbers according to certain rules. When using this number, the number "0" is not needed.

At that time, a scholar of the Roman Empire discovered the symbol "0" from Indian notation. He found it very convenient to use "0" for mathematical operation, and he was very happy. He also introduced the Indian method of "0" to everyone. After a while, it was known by the pope at that time. At that time, it was the Middle Ages in Europe. The power of the church was very strong, and the power of the pope far exceeded that of the emperor. The Pope was very angry. He rebuked that the sacred number was created by God, and there was no such monster as "0" in the number created by God. Anyone who wants to introduce now is blasphemous! So the Pope ordered the scholar to be arrested and tortured, and his ten fingers were tightly clamped with a clamp, so that his hand was disabled and he could no longer write with a pen. In this way, "0" was banned by the ignorant and cruel Pope.

However, although the use of "0" is forbidden, Roman mathematicians still use "0" secretly in mathematical research regardless of the ban, and still make a lot of mathematical contributions with "0". Later, "0" was finally widely used in Europe, but Roman numerals were gradually eliminated.

4. Tang Priest and his disciples picked peaches.

One day, the Tang Priest told his disciples Wukong, Bajie and Friar Sand to go to Huaguoshan to pick peaches. Before long, the three disciples returned happily after picking peaches. Tang Priest and his disciples asked: How many peaches did each of you pick?

Bajie said with a silly smile, Master, let me test you. Each of us took the same amount of money. There are less than 65,438+000 peaches in my basket. If we count three peaches, there are 1 peach left in the end. Do the math. How many did each of us choose?

Friar Sand said mysteriously, Master, I will test you, too. If there are four peaches in my basket, there is 1 left in the end. Do the math. How many did each of us choose?

Wukong smiled and said, Master, I'll test you, too. If there are five peaches in my basket, there is 1 left in the end. Do the math. How many shall we each choose?

Tang Priest quickly said the number of peaches he had picked. Do you know how many peaches they each picked?

fence

A farmer invited engineers, physicists and mathematicians to enclose the largest area with the least fences. engineering

The teacher drew a circle and declared that it was the best design. Physicists pull the fence into a long straight line, assuming that

The fence is infinitely long, so I think it is big enough to enclose half the world. The mathematician gave them a big laugh. He seldom uses fences.

Barbara surrounded herself and said, "I'm outside now."
