In the following days, more and more teachers were summoned by Lu Heng from all over the place.

The academy, which was originally a little deserted, gradually became lively.

It's just that now although the teacher has almost summoned.

However, due to spring ploughing, Lu Heng still decided to postpone the start of school for a few more days.

It just happened to be able to take this opportunity to train these teachers recruited from Chang'an City.

It's just that there are almost 300 teachers in total.

So a classroom will definitely not be able to sit down.

Lu Heng simply divided them into three classes.

Then Sun Lao, Li Mingyu and Xiao Wuzhao were sent to teach them.

Anyway, the class is not complicated, the main thing is to teach Arabic numerals and mathematical symbols.

Speaking of classes, it is more important to let them adapt to the teaching mode of the college.

After all, most of the people here have only gone to private schools for enlightenment.

The rest of the time is probably self-study or study tours.

So it's like this scene of dozens of students studying together.

It's better to let them experience it first.

In addition, although Lu Heng did not go to give them a lecture in person.

But I'll always be watching in three classes.

So I'm not afraid of anything going wrong.

It's just that this is the case for Lu Heng.

But for Li Chunfeng and them, such a class is a bit tormenting.

Although the current Tang Dynasty has not yet developed to the kind of male and female defense after the Song Dynasty.

But I originally thought that I was here to be a teacher.

Now I have to be a student first.

Teaching on the podium, but she is still a young girl.

This really makes many people feel uncomfortable.

Looking at the following teachers who are all restless, waiting to be on the job.

Lu Heng couldn't help but laugh secretly in his heart.

The reason why he had to arrange for three people to take turns lecturing the three classes.

Except that because the three of them have been learning with themselves for the longest time.

This knowledge is the most reliable.

The bigger reason is to use martial arts to give them a dozen vaccinations.

Lay a good foundation for gender equality in the later colleges!

At this time, Wu Zhao, who was lecturing for the first time, was nervous.

But fortunately, Lu Heng has always been standing next to Jiangtai.

So after holding the chalk and writing on the blackboard to pull a row of board books.

It was still according to what Lu Heng had taught them before.

After clearing his throat, he pointed to the board book on the blackboard with his whip and taught:

"The names of these symbols that I wrote on the blackboard are called Arabic numerals."

"It was created by the Arabs outside the Western Regions."

"Because their penmanship is simple and great for writing."

"So Lu Shanchang chose them as universal mathematical symbols."

"Now let's get to know them with me."

"I've written down the numbers corresponding to each of them, so you can take a good look at them."

When Wu Zhao said this, he paused for a moment, and gave a little time to the students in the audience as Lu Heng taught them.

Let them look carefully at the content on the board and absorb what they have just said.

After feeling that the time was about the same, Wu Zhao also followed Lu Heng's convention.

He asked, "If you have any questions, or if you don't understand something, you can raise your hand and ask now." ”

"If we all understand, we'll move on."

But as soon as this sentence was spoken, a teacher standing up and saying:

"Wait a minute, I actually don't understand it, although these numbers should be written more simply."

"But I don't think they're much more convenient, so why do we have to use them instead of our own words?"

Faced with this question, Wu Zhao was just about to answer, but Lu Heng raised his hand to stop him.

Then he said to the teacher who was standing and asking questions:

"First of all, it's good that you can ask questions in class, and you should encourage students to do that when you become teachers."

"But secondly, there is a rule of classroom discipline in our college."

"Whether you are a student now, or a teacher in a few days."

"Classroom discipline is something that everyone must practice."

"It's okay to ask questions, but first you need to raise your hand."

When Lu Heng said this, he raised his right hand straight above his head and made a demonstration.

Then continues:

"Secondly, when you ask a question, you must address the teacher, although we may have more students to teach in a class now."

"But this fine tradition of respecting teachers and respecting the way cannot be lost."

After Lu Heng said this, he pressed his hand and motioned for the teacher who was asking the question to sit down.

This allowed Wu Zhao to begin to answer his question.

Wu Zhao cleared his throat and replied:

"That's a good question, and that's what I'm going to talk about right away."

After Wu Zhao finished speaking, he picked up the chalk and wrote two lines on the blackboard.

After writing, Wu Zhao pointed to them and said:

"On it are ninety-nine thousand nine hundred and ninety-nine in Arabic numerals."

"Below are the ninety-nine thousand nine hundred and ninety-nine of our Chinese characters."

"Now that you look here, don't you intuitively feel the difference between them?"

"So here, I would like to tell you the first thing about Arabic numerals."

"That's the decimal system of freedom."

"What is the decimal system?"

"To put it simply, for every extra ten, we can add one more to the previous number."

"With such a feature, it can bring great convenience in written operations."

"For example, you see I write these two numbers now, one is 155 and the other is 14, so 155 + 14."

"We just put them in single digits, write them together vertically, and then put a plus sign next to them."

"It's easy to add them up and get their results."

After Wu Zhao finished talking about this topic, he still learned from Lu Heng when he taught them.

I wrote two similar formulas on the blackboard.

He said to the students in the audience: "Now, is anyone willing to come up and do these two questions?" ”

"If you want to, you can raise your hand."

Seeing that the group of big men in the audience didn't raise their hands, Wu Zhao, who had already found some states at this time, was not stage frightened.

Directly continued: "Then since you don't raise your hands, I'll choose whatever you want." ”

After speaking, Wu Zhao randomly selected two people from the audience.

Let them come up and do these two questions.

With such a simple question, it is naturally impossible for these people to make mistakes.

So Wu Zhao praised the two of them.

I started to talk about it again.

And Lu Heng, who had been standing on the sidelines of the stage, looked at the teachers who were waiting to be hired in the audience.

It seems that they have slowly begun to listen to it.

At this time, it can be regarded as a complete relief.

So he quietly moved his footsteps, walked out of Wu Zhao's class, and went to look outside the other two classrooms next to him.

The situation in these two classrooms also made Lu Heng quite satisfied.

Needless to say, Old Man Sun not only has a huge prestige blessing.

His optimistic personality is also very good at motivating students.

So a class is very vivid.

The teachers in the audience who were waiting to take up their posts also listened very carefully.

And Li Mingyu's side is like this, although Old Man Sun has such a ability.

But the students sitting in the audience, who did not know her princess status.

So almost everybody is sitting upright.

Don't dare to make the slightest gesture that might be rude.

As a result, although the atmosphere in the whole class seems a little dull.

But it still went well.
