Chu Tang: Tell Li Er at the beginning that I am a time traveler

Chapter 81 Who Am I, Where Am I From, Where Am I Going?
Zhenguan four years.

Autumn, September.

The day before the clothes leave, Li Chong also had to rush the ducks to the shelves, and came to the Imperial College to teach the students a lesson.

In fact, mathematics was not very popular in ancient times. It can be both good and professional, and there is even a saying that it is cheap. However, because of Li Chong's reputation, almost the entire Imperial College students came.

Li Chong also couldn't talk about those castles in the air.

Because practicality is king.

therefore……

I had no choice but to pick some that were mentioned in the Nine Chapters of Arithmetic, but they were very complicated, and then used number symbols to give them a new calculation method and perspective.

For example, in Nine Chapters of Arithmetic, there is the content of the square root, but the content of the square root would make normal people dizzy after reading it.

Then this Li Chong can talk about it.

Then after listening to Li Chong's lecture, those students who were not good at arithmetic couldn't help but burst into voices of sudden enlightenment.

have to say!

This is simply too simple and easy to understand!

even……

Li Chong also invited someone up on the spot to do a practice question.

The other party figured it out immediately.

Li Chong's calculation method is famously simple, easy to understand, and convenient.

Of course!
There is also a downside.

That is very waste paper.

But you can also use no paper, and it's the same if you write directly on the ground.

Through this, Li Chong finally managed to muddle through.

To be honest, I can't come next time.

because……

There really isn't much to say.

It's too esoteric, the key things are not used, and it's too shallow, generally only need brainless sequence equations to solve.

In other words, the originally thick arithmetic book now only left a simple equation.

To be honest, Wang Xiaotong has already begun to wonder whether the previous research results should be eliminated.

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

"Li Xueshi, your numbers and symbols are clear and easy to understand, simple and clear. In contrast, most of the works of predecessors are obscure and difficult to understand. It is more difficult for teaching and students to understand."

"Occasionally, the old man wonders whether the calculation method related to the calculation method should be discarded."

Li Chong can actually understand the other party's thoughts, just like later generations, except that ancient book lovers will go to read the nine chapters of arithmetic, find out some glorious history of the ancients from it, and use it to pretend to be aggressive in front of others, to be honest , who still uses the method proposed in Chapter Nine Arithmetic to perform calculations?
The key is, will you come out with calculations every day?
In fact, the calculation methods in these ancient books are very closely related to the calculation methods and calculation methods of calculating chips.

This is a very sad thing.

Li Chong said: "I can understand your mood. But I have no good solution."

In fact, the development of ancient Chinese mathematics is still very strong.

Even without the use of equations and functions, many problems can be solved, and some calculation methods even surpass those of the West for hundreds of thousands of years. These methods seem to collapse directly.

Don't forget your origin, but people's habit of seeking profit tells Li Chong that future generations will definitely forget their origin.

but……

Is it because of this that you don't learn and just keep studying the things of the ancients?

It doesn't seem to be possible either.

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

Wang Xiaotong did not expect Li Xueshi to be so broad-minded.

The admiration for Xueshi Li couldn't help but arise spontaneously again.

"Speaking of it...I want to discuss with you, Xueshi Li, the solution of multiple equations."

"Cough! Many times... Actually, I'm not very good at it. You are 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 perverted.

Look down on this old man!
Wang Xiaotong also looked at Li Xueshi and thought to himself, Li Xueshi has talent, but he is a bit lazy.

If one day, he dies...

Then, he watched Li Xueshi leave the Imperial College.

The horse under Li Xueshi's crotch is not bad.

After all, young people.

this fall.

Li Chong also went hunting with Li Chengqian.

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

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

How easy it is to cause misunderstandings by others.

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

This left Li Chengqian speechless.

"Of course! Gan'er, your heart is still good, and it's all just to protect your teacher and me. I'm still very relieved about this."

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

Li Chong didn't seem to like reasoning with Li Chengqian very much, and the two were just hunting.

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

Because almost all places in Guanzhong of Datang this year have bumper harvests.

This made Sun Simiao couldn't help urging Li Chong to make the alcohol quickly.

As a result, this year's hunting felt more or less hastily ended.

Of course, Li Chengqian did not complain.

Because the current him has obviously broken away from these low-level interests.

Just when I think that I can only live in the palace every time, but I get farther and farther away from the teacher, and I can't often see what the teacher is doing, and I feel regretful.

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

He used to be very clingy, but now he is obviously not so clingy.

only……

It is estimated that there will also be some confusion and confusion, especially about who I am, where I come from, and where I am going.

He is the prince of the Tang Dynasty, he came from the womb of his queen mother, and he wants to...

That's right!

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

"Brother, why are you in a daze!?"

A person suddenly appeared in front of him, startling him.

Li Chengqian took a closer look, and coupled with this crisp voice, it wasn't Li Lizhi or anyone else.

Recently, he studied hard every day, and his mother knew about it, so sometimes Li Lizhi would come to bring him soup and supplements.

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

But it was said that she gave it, but in fact it was brought by the servants of the Shangshi Bureau, she was just going through the motions.

Nothing needs to be done at all.

"Lizhi, you are here again."

"Isn't it okay for me to see my brother?"
