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.
Children, do you know the story of Gauss, a mathematical genius, when he was 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!
In daily life, mathematics is everywhere, such as: buying and selling vegetables, calculating how much …
The following is a short story, a story between numbers.
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?
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 will be 1 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?
A mathematician boasted that his mental arithmetic ability was extremely strong, so someone came to test the mathematician: "At first, there was a bus with 57 people on it. 27 people get off at the first stop and get on 14 people; At the other stop, 5 people get off and 12 people get on; At the last stop, 16 people get off and 2 1 people get on. " The mathematician said contemptuously, "Can you beat me with this?" There are still 63 people left in the car. "People shook his head and said," that's not what I asked. I asked how many stops this bus has passed. "
I don't know, but this?
Xiao Zhao, Ding Xiao and Xiao Zhang are teachers, doctors and lawyers respectively. They only know: (1) Xiao Zhao is older than the teacher; (2) Xiao Zhang and the teacher are of different ages; (3) Xiao Zhao and a lawyer are friends. Can you infer who is a teacher, a lawyer and a doctor?
According to (1) Xiao Zhao is older than the teacher and (3) Xiao Zhao is a friend of a lawyer, it can be inferred that Xiao Zhao is neither a teacher nor a lawyer, so Xiao Zhao is a doctor. According to speculation, Xiao Zhang is a lawyer and teacher, Xiao Zhao is a doctor, so the rest of Ding Xiao are teachers.
This topic is very simple. By using the method of exclusion, for example, according to conditions (1) and (3), we can see that Xiao Zhao is neither a teacher nor a lawyer. Analogy can give the answer.
One day, the Tang priest wanted to test the math level of three disciples, so he called them to him and said, "Now, disciples, I'll write three numbers on the ground. If you can read them accurately, I will pass them on to him. "
The Tang Priest first wrote: 23456. Pig Bajie couldn't wait to say, "Read this in two three four five six!" "The Tang Priest shook his head and said," Bajie, the pronunciation of multiple digits is regular. From right to left, each number is one, ten, one hundred, one thousand and ten thousand. Read each number from left to right, and then add ten thousand, one thousand and one hundred and ten. Be careful not to read the last number as "one". Therefore, 23456 is pronounced as 23456. "
Tang Priest also wrote: 130567. The Monkey King immediately said, "It's too easy, pronounced130,567." The Tang Priest shook his head again and said, "Pay special attention to zero. When there is a zero in the middle of a string of numbers, read only the zero and don't read the following numbers. So this number should be read as 130567. "
The third number is 120034. Friar Sand thought for a moment and said, "It should be pronounced 120034." The Tang Priest sighed and said, "If there are several zeros in a string, just read one. So this number should be read as 12034. Disciples, you are not very good at math. You have to keep trying. I can't pass on the scriptures to you for the time being! "
One day, Bajie went to Huaguoshan to find Wukong, but unfortunately the Great Sage was not at home. The little monkeys warmly entertained Bajie and picked 100 of the most delicious mountain peaches. Pig said happily, "Let's eat together, let's eat together!" How to eat? Counting ***30 monkeys, Bajie found a branch and drew it on the ground, and listed the formula, 100 ÷ 30 = 3... 1.
Pig Bajie pointed to the top three and said generously, "You can eat three peaches each. Look, the rest 1 I ate it! " The little monkeys were very grateful to Bajie and thanked them one by one. Then each of them took his share and ate it from the side.
When Wukong came back, the little monkeys told Wukong how generous Bajie was today and why he only ate a pecan. Seeing Pig's arrangement, Wukong shouted, "What a fool! I'll find him! "
