Zhenguan for four years.

Autumn, September.

The day before the clothing leave, Li Chong also had to catch ducks on the shelves, and came to Guozijian to teach the students a lesson.

In fact, mathematics was not very popular in ancient times, it can be both clear and not professional, and there is even a saying that there are ninety-nine cheap skills, but because of Li Chong's reputation, almost the entire Guozijian students came.

Li Chong can't talk about those things in the air.

Because practicality is king.

Therefore......

I had to pick some things like the nine chapters of arithmetic, which were mentioned, but they were very complicated, and then used the way of number symbols to give them a new calculation method and perspective.

For example, in the nine chapters of arithmetic, there is the content of the prescription, but the content of this prescription is dizzy for normal people.

Then Li Zhong can talk about it.

Then after listening to Li Chong's lecture, those students who were not good at arithmetic couldn't help but let out a burst of sudden realization.

I have to say!

It's so easy to understand!

Even......

Li Chong also invited a person to go up on the spot and did a practice problem.

The other party immediately figured it out.

Li Chong's calculation method, which is notoriously simple to understand, and convenient.

Of course!

There is also a drawback.

That's a lot of waste paper.

But you can also do without paper, and it's the same if you write directly on the ground.

Through this, Li Chong finally barely got by.

Truth be told, I can't come next time.

Because......

There's really not much to say.

It's too profound, the key things are not needed, it's too shallow, and it generally only needs to be solved without brain-listed equations.

Otherwise, the original thick arithmetic book is now only a simple equation.

Wang Xiaotong told the truth, and he has already begun to struggle whether the research results of his predecessors should be eliminated.

When he sent Li Chong back, he mentioned this to Li Chong.

"Mr. Li, your numbers and symbols are clear and easy to understand, simple and clear, but looking at the works of your predecessors, most of them are obscure and difficult to understand, and it is more difficult to teach and students to understand."

"The old man sometimes wonders if the calculation method related to the calculation should be abandoned."

Li Chong can actually understand the other party's thoughts, just like the next generation, except for ancient book lovers who will go to see the nine chapters of arithmetic, and find out some of the glorious history of the ancients from it, which can be used to pretend to be forced in front of others, to be honest, who still uses the methods proposed in the nine chapters of arithmetic to calculate?

The point is, do you bring the calculations with you every day?

In fact, the calculation methods in these ancient books are very closely related to the calculation methods and calculation methods of the calculation chips.

This is a very sad thing.

Li Chong said: "I can understand your feelings. It's just that I don't have a good solution. ”

In fact, ancient Chinese mathematics was still very well developed.

Even if you don't use equations and functions, you can solve many problems, and even some calculation methods exceed the West for hundreds of thousands of years.

Let's say don't forget your roots, but people's habit of seeking profit tells Li Chong that future generations will definitely forget their roots.

But......

Is it because of this that I don't learn, and I just hold on to the things of the ancients and keep my head immersed in studying?

It doesn't seem to be either.

So in the end, Li Chong could only suggest: "Even if no students are willing to learn in the future, we must also retain the wisdom of these sages in the past, so that future generations can know that there are not only equations and functions, but also the numbers and symbols I wrote." ”

Wang Xiaotong didn't expect that Mr. Li would be so open-minded.

The admiration for Mr. Li can't help but arise spontaneously again.

"Speaking of which...... I would like to discuss with you, Mr. Li, the solution of multiple equations. ”

"Ahem! Multiple ...... Actually, I don't know how to do it. You're better than me! ”

Because of Wang Xiaotong's work, Li Chong also read it, this guy can actually calculate cubic polynomial equations, it seems that the ancients were all perverts.

Underestimate this old man!

Wang Xiaotong also looked at Bachelor Li, and thought to himself, Bachelor Li, he has talent, but he is a little lazy.

What if one day, he died......

Then, he watched Master Li leave the Guozijian.

This horse under Mr. Li's crotch is good.

In the end, it is young people.

This fall.

Li Chong also went out hunting with Li Chengqian.

By the way, he also asked Qian'er not to speak next time he couldn't speak, because at the court meeting, Li Chengqian almost ruined his reputation.

Although your teacher and I like beautiful women, don't say it so bluntly.

That's easy to misunderstand others.

What if I can't marry a wife in the future?

This left Li Chengqian speechless.

"Of course! Qian'er, your heart is still good, it's just to protect your teacher and me. I'm still very pleased with this. ”

This year's hunting is very different from previous hunting.

Li Chong doesn't seem to like to reason with Li Chengqian very much, and the two are just hunting.

I didn't ask the people how this year's harvest was, as in previous years.

Because almost everywhere in Datang Guanzhong this year has a bumper harvest.

This made Sun Simiao urge him to hurry up and ask Li Chong to hurry up and make the alcohol.

So much so that this year's hunting has a more or less hasty ending.

Of course, Li Chengqian did not complain.

Because now he has obviously departed from these low-level interests.

It's just that I think that I can only live in the palace every time, but I am getting farther and farther away from the teacher, and I can't often see what the teacher is doing, and I feel regretful.

has been taught by Li Zhong for so long, and his current thinking has gradually become independent.

Before, he would be clingy, but now it's noticeably less sticky.

Merely......

It is estimated that some confusion and confusion will also begin to appear, especially who I am, where I am from, and where I am going.

He is the prince of the Tang Dynasty, he came from his mother's belly, and he wants to ......

That's right!

He had no idea where he was going. And now, what should be done?

"Brother, what are you doing in a daze!?"

A man suddenly appeared in front of him and startled him.

Li Chengqian looked at it fixedly, coupled with this crisp voice, it was not Li Liqian, who else.

Recently, he has been studying hard every day, and his mother knows about it, so sometimes he will ask Li Lizhi to bring him soup and supplements.

As for Li Liqian, she felt that she had nothing to do anyway, so she took over this task.

But she said that she sent it, but in fact, it was brought over by those slaves and maids from the Shangshi Bureau, and she was just going through the motions.

There is no need to do anything at all.

"You're here again."

"Shall I come to see my brother?"
