A short story about mathematics (about 50 words)

About 1,500 years ago, European mathematicians did not know how to use "0". They use Roman numerals. Roman numerals use several symbols to represent numbers, and according to certain rules, they are combined to represent different numbers. In this use of numbers, the number "0" is not needed.

At that time, a scholar in the Roman Empire discovered the symbol "0" from Indian notation. He found that with "0", it was extremely convenient to perform mathematical operations. He was very happy and introduced the Indian method of using "0" to everyone. After some time, this matter was known to the Pope of Rome at that time. It was the Middle Ages in Europe, the church was very powerful, and the power of the Pope far exceeded that of the emperor. The Pope was very angry. He rebuked that the sacred numbers were created by God. There is no monster "0" in the numbers created by God. Whoever wants to introduce it now is blaspheming God! So, the Pope ordered that the scholar be arrested and tortured. His ten fingers were clamped tightly with clamps, which made his hands disabled and he could no longer hold a pen and write. In this way, "0" was expressly banned by the ignorant and cruel Pope of Rome.

However, although the use of "0" was prohibited, Roman mathematicians still ignored the ban and still secretly used "0" in mathematical research, and still used "0" to do a lot of mathematics. contribution to. Later, "0" was finally widely used in Europe, while Roman numerals were gradually phased out.

Children, do you know the story of the mathematical genius Gauss when he was a child?

When Gauss was in primary school, one time after the teacher finished teaching addition, because the teacher wanted to take a break, he asked the students to do calculations. The question was:

1+2+3+ ..... +97+98+99+100 = ?

The teacher was thinking, now the children must be at the end of get out of class! Just when he was about to make an excuse to go out, he was stopped by Gauss! ! It turns out that Gauss has already calculated it. Children, do you know how he calculated it?

Gauss told everyone how he calculated it: add 1 to 100 and 100 to 1 in two rows, that is to say:

1+2+3+ 4+ ..... +96+97+98+99+100

1099+98+97+96+ ..... +4+3+2+1

=101+101+101+ ..... +101+101+101+101

***There are one hundred 101s added, but the calculation is repeated twice, so Divide 10100 by 2 and you will get the answer equal to <5050>

From then on, Gauss’s learning process in elementary school has already surpassed other students, which laid the foundation for his future mathematics and made him become—— Math genius!

In daily life, mathematics is everywhere, such as: buying vegetables, selling vegetables, calculating how much money...

The following is a short story, which is between numbers. story.

One day, when the number cards were having lunch together, the youngest one started talking.

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

O's brothers and sisters said in unison: "Okay. Ah.”

Brother 8 said, “Brother 0’s idea is really good. I’ll just be a good person for once. My brother 8 will supply cameras and film, okay?”

Old 4 spoke: "Brother 8, it's good, but it's a little too troublesome. You might as well use my digital camera. That's it."

”

So, they became busy, and finally + number helped them take the photo, and immediately sent the digital camera to the printing shop, and the printing was done. The computer sister asked them for money because of her skills, but Who is paying? They all looked at each other blankly, and this is what the computer sister said: "One *** five yuan, you have eleven brothers and sisters, how much do you pay on average? "

Among the eleven of them, the sixth one is the smartest. This time it was the first to calculate the result. Do you know how it calculated it?

Tang Seng and his apprentice picked peaches

One day, Tang Seng ordered his apprentices Wukong, Bajie, and Sha Seng to go to Huaguo Mountain to pick some peaches. After a while, the three apprentices came back happily after picking peaches. Master Tang Seng asked: How many peaches did each of you pick?

Bajie smiled and said: Master, let me test you. We each picked the same number of peaches, but there are not enough peaches in my basket. 100, if you count 3 by 3, there will be 1 left.

Sha Seng said mysteriously: Master, I will take the test too. Test you. If you count the peaches in my basket 4 by 4, how many peaches do we have each picked?

Wukong said with a smile: Master. , let me test you too. If you count the peaches in my basket 5 by 5, there will be 1 left.

Tang Monk is very good. Tell me the number of peaches each picked. Do you know how many peaches each picked?
