Chapter 118: Arabic Numerals? No, light and numbers

With two classes, Zhao Zilong made the students who were originally fond and neutral of Hongdu Gate School like his classes. Pen × fun × Pavilion www. biquge。 info

"Hurry, hurry, hurry!" One by one, the students kept urging their peers to go to the class today.

You must know that in the last class, Mr. Zhao was talking about Chenshi, and just after the time, Liu Qi closed the door of No. A and No. B according to his order, and the students who were late could only be outside the windowsill.

Seeing the wonderful scenes in the classroom, I can't wait to be one of them.

In fact, in this era, respect for teachers is very common, at least in the field of ethnology, no student dares to be late.

However, there are two sides to everything, when it comes to Hongdu Gate School, just like the universities of later generations, the students here will be assigned by the emperor to serve in various places after completing their studies.

There seems to be a convention between the PhDs and the students, and many students no longer abide by classroom discipline, and latecomers abound.

After all, from the door to the school to become an official in various places, teachers are also human beings, and there are relatives and relatives who need to be taken care of, maybe they will ask these students to do things in the future.

There are even some students who seem to be deliberately late in order to show their identity.

It's a pity that this one is not good at all in Mr. Zhao's place, so he stayed outside the door when he was late, and didn't see Liu Qi and his friends, staring at the door one by one?

I believe that as soon as the time comes, they will instantly close the door of A and B, just like last time.

Finally, I felt that the students were very relieved, and when they saw that they wanted to cry without tears, they hurried and ran from home to class, only to find that there was no place.

Fortunately, Liu Qi is not such an old-fashioned person, so he asked someone to bring benches and put them in the aisle.

Eventually, they couldn't even sit down in the aisles, and the rest of the students had to sit outside the windows on benches to listen to the lectures.

Seeing that Chen Shi was getting closer and closer, Mr. Zhao finally appeared, no, there were three more people next to him.

Good guy, the students are not calm, and the ones who follow him are naturally the disciples who enter the room.

Many people are full of regret, why don't I take the initiative in Mr. Earlier's class? Why don't you stand by his side like that without me? No, this class must be performed well and enter Mr. Zhao's eyes.

It can also be seen from the ranking that Qin Caihong is closely following him, then he must be the eldest disciple, Chu Weidong is second, and Gao Yuesheng is last.

"You can distribute it," Zhao Yun commanded softly as soon as he walked into the classroom, and then raised his voice: "I am very pleased to be a teacher, there are more and more students who come to listen to the class, which also means that my class is okay." ”

The good thing is that in today's classroom discipline, although you can be late for some occasions, you are not allowed to make any noise.

Hearing his words, the students invariably smiled knowingly. As the first three disciples of Mr., Qin Caihong, Chu Weidong, and Gao Yuesheng, they all had glory on their faces and their chests held high.

What is this?

The students' faces were instantly confused, and they couldn't understand what they were holding in their hands at all.

Seeing that the three disciples were empty-handed for a while, Zhao Yun was not only very surprised.

In his opinion, the rush to produce 1,000 copies should be enough for the students' requirements, but who knows that the entire classroom will be gone before it is finished.

With the example of the three people, other people who may be familiar with them stood up one after another to help distribute it, and the whole process was not even half a pillar of incense, and all the distribution was completed.

"Those who didn't get the handouts, ask your classmates to copy a copy after class." Zhao Yun saw that the time was just the hour, so he began to teach.

Seeing that Liu Qi was about to order his subordinates to close the door, he waved his hand: "I'm sorry Mr. Liu, you don't have to close the door today, otherwise the students outside won't be able to hand it in if they have questions, thank you." ”

Liu Qi smiled and retreated with his subordinates with some embarrassment.

"You have seen what you have in your hands, rainbow, and in the future, you can organize the handouts for the teacher into a book for those classmates who have not received the handouts."

Before the lecture began, Zhao Yun first vaguely mentioned the three people, which was regarded as an official recognition of their status.

Although Qin Caihong and Chu Weidong were excited, their faces twitched silently, and Gao Yuesheng almost burst into tears.

"In the long process from barbarism to civilization, our ancestors gradually understood the concept of number and shape." Zhao Yun's voice was subdued and frustrated, even if a person who practiced martial arts lost his internal strength, it was completely different from the hoarse voice of an ordinary doctor.

"Neolithic pottery is mostly round or other regular shapes, with various geometric patterns on the pottery, and often three landing sites, all of which are the germ of geometric knowledge."

"In the pre-Qin classics, there are records of the number of subordinates, knotted ropes, and carved wood, which shows that people gradually understood the number from distinguishing the number of things, and created the symbol of counting."

"There are 13 counting words in the Yin Shang oracle bone inscription, the largest number is 30,000, and the smallest is one. One, ten, hundred, thousand, thousand, each with its own proper name. There is already a germ of the decimal position value system. ”

"Today, what the teacher gives you is a new concept of numbers, and the numbers written in Chinese characters have a special symbol. Ladies and gentlemen, we are all on the road to arithmetic. ”

"In the future, I hope that you can go further on the road of spreading arithmetic, because this discipline is closely related to our lives, and you have a long way to go."

In the first two lessons, the students had questions to ask, after all, they had all dabbled in it.

Today, however, no one has spoken. Perhaps they have been exposed to arithmetic, but unfortunately, none of them have reached a certain height.

Even if some people have a family background, they don't dare to interrupt at will, for fear that their problems will be naïve or something, and others will laugh at them.

Although some people were very confused, they had to listen carefully, Mr. Zhao even created a cloud body, what is the point of creating a few numbers?

Because in the eyes of ordinary people, although arithmetic is one of the six arts of a gentleman, it is still located in an inconspicuous position.

"1 is one, 2 is two, 3 is three・・・・・・・・"

The people listening to the lecture outside the window were a little crazy, they didn't have handouts in their hands, and they didn't know what one was even one, one was not one, was it two?

However, some students have also been slapped in the face in the past, since the students in the classroom have no doubts, they don't dare to let Liu Qi's people pass the note in again, waiting for the end of class to borrow a lecture to read.

Fortunately, Mr. Zhao said that in the future, Qin Caihong and the other three will print out the handouts, so let's find them.

At this moment, the three people standing quietly on both sides of the classroom don't know that they have been remembered by many students, but this is a good thing.

"I'm sure you've all been exposed to sentence reading, and you're separated by commas in the middle of some large numbers."

"It's very simple, a number from the bottom up, every three digits is a comma."

"The first comma, preceded by a thousand; The second comma is preceded by millions, and the third comma is preceded by billions. ”

"Generally speaking, in today's society, 100 million is enough for our lives."

"Latecomers find out that the numbers are not enough, and that's their business."

"It coincided with the Guanghe period of my great Han, so the number is called Guanghe number."

At this time, Zhao Yun also had to pull up the tiger skin of the Spirit Emperor to facilitate the promotion of numbers.

"Gentlemen, one day if Mengtong knows how to read and write numbers, it must be your credit, thank you for the teacher."

As he spoke, Zhao Yun bowed slowly. (To be continued.) )
