As soon as the three arithmetic questions were distributed, the students of Guozijian answered them seriously.

However, at first, some people were not convinced, saying that it was impossible to calculate the answers to these questions, until someone took out Li Chong's solution process.

Duration......

Even the students of Hongbunkan know about it, so they have to take a look at it with curiosity.

As a result, they were all killed.

In this process, Li Chong's reputation is getting louder and louder, even louder than when he was the prince's teacher.

After all, this is something that both parents and children know.

In particular, whether it is the Guozijian or the Hongwen Pavilion, these are all the descendants of the emperor's relatives, nobles, and nobles.

Even......

Because Li Chong's title is too perverted, so much so that Empress Changsun and Li Lizhi all know about it.

On this day, Empress Eldest Sun took the title and looked at it.

She knows every word on the paper, but you say how to count.

Her mind was completely empty.

Speaking of which......

Will Lizhi also learn arithmetic in the future?

Although there will definitely be someone in the princess's mansion who will do this kind of thing in the future, he can't not understand it at all.

Of course, like Li Chong, forget it.

There's no need to learn that deep.

"Queen Mother, I'll fan you."

"Why don't you learn arithmetic too?"

“……”

……

It's May.

The humid and sultry heat of the Tai Chi Palace has been revealed.

Li Er also regretted that he shouldn't have listened to Li Chong's words.

This Taiji Palace is really not a place for people to live in summer.

But now, he is no longer allowed to ask where he wants to go to escape the heat.

This year, let's hold on.

On the Hongwen Pavilion side, there are even fewer students, only about 30 people.

In the beginning, they mainly studied calligraphy, but gradually they had to take care of other things.

I have long given up trying to solve those problems.

However, since they knew the answer to Li Chong's first question and the steps to solve it, some of the questions in the previous "Nine Chapters of Arithmetic" didn't seem to be so difficult.

Whatever you don't know, whatever you don't know, you will know it.

In an instant, many people seemed to have been directly opened to the Tianling Gai, and there was a kind of thing, there is nothing that cannot be solved by column equations, if there is, then list another one.

In addition, they didn't know where to go, and they got the question from Li Chunfeng that Li redid again.

In an instant, the originally thick nine-chapter arithmetic now seems to be only a simple equation left.

Of course, this is an exaggeration, but it is indeed a revolution that turns their imagination on its head.

So much so that the doctors, who are specifically responsible for teaching arithmetic, are a little unhappy.

After all, the old man, in his heart, always can't help but reject new things.

Not to mention, the students are still desperately applauding the column equations.

Compare what he taught with what Li Zhong used.

Then who can accept it.

All I can say is......

Li Zhong still lacks a little way to deal with people.

Li Zheng told Dr. Ren this method first, and Dr. Ren will definitely not feel uncomfortable in his heart.

But how can Li Chong be blamed for this?

Li Chong didn't say that his column equation was better than the positive and negative technique of his ancestors.

Now the status of a doctor of arithmetic is very awkward.

Maybe, in two days, they will have to pack up their bags and leave.

The main thing is that I can't afford to lose that face.

There are only three days left until the one-month deadline.

After thinking about it, the doctor of arithmetic still came to find Li Chong. It's not that he came to Li Chonggan, but humbly asked for advice.

Li Chong heard that he was the doctor of Guozijian, and of course he welcomed it warmly.

And then......

The two began to discuss the topic.

From "Nine Chapters of Arithmetic" to the rest of the arithmetic, he found that Li Chong didn't know much, so he ......

Maybe it's just that Li Chong accidentally invented such an algorithm, but there is no need to take Li Chong too seriously.

But......

This is indeed an epoch-making invention, and with this symbolic system, the solution of any unknown seems to become as straight as a intestine.

When students understand why they do that, they don't have to be so bitter and difficult to understand.

Of course, there is also the matter of discussing the remaining two topics with Li Chong, although this is a bit unruly.

But Li Chong didn't hide it.

And when the other party left, the other party's whole person seemed to be in a trance.

It's horrible!

Is this something that a human can do?

At that moment, when he left Li Chong's house, the other party only had such thoughts.

It involves functions, coordinate systems, binomial expansions in the form of fractions, calculus, and area calculations for graphs in general.

When he returned to Guozijian, that person was called a genius who learned from school, and since then it has spread in Guozijian.

Right!

It's not that you're inferior to others, it's that the other party isn't human at all.

Guozijian was also extremely surprised, whether it was Guozi's sacrificial wine, or other doctors, teaching assistants, or something.

After all, they are doctors of arithmetic, they were born during the reign of Emperor Wu of the Northern Zhou Dynasty, and it can be said that they have been studying arithmetic all their lives, whether it is when they are sleeping or eating, it is not an exaggeration to say that they are the most authoritative here, and they have all been evaluated by him like this, so how terrible is this Li Chong.

I'm afraid I don't have three heads and six arms?

Can you crush boulders in your chest?

And after being depressed for a day, Wang Xiaotong also figured out that such a talent should be recommended to His Majesty and let him come to Guozijian to be a doctor of arithmetic together.

Soon......

Li Er received Wang Xiaotong's recital, which praised Li Chong, and even Li Er was a little suspicious, this was still not the Li Chong he knew.

The key, in addition to ability, Wang Xiaotong also said a lot of Li Chong's good character, like what is very generous to teach people, and has the demeanor of a famous person.

Wang Xiaotong has studied arithmetic for decades, and it is the first time that he admits that he is inferior to others.

In the past, he was even Liu Hui, Zu Chongzhi, and Zu Xuan, who dared to spray.

Li Er also said that I knew.

However, if you want to be a doctor of arithmetic together, it may be that Li Chong's rotten appearance should not go, and if you go, you will definitely not teach seriously, and you will definitely fish for three days and dry nets for two days.

Finally......

A month passed.

The moment has come when the long-awaited answer will be announced.

Li Er won't join in this fun, mainly because it is inappropriate.

However, Li Chengqian did not have such scruples.

Thereupon......

Under the coordination of many parties, His Royal Highness the Crown Prince also presided over this academic exchange meeting, and the venue was placed in Guozijian.

All I can say is...... This exchange meeting was also held very successfully, because in the end......

When the results came out, almost everyone couldn't help but shout a foul word.

It can be seen how successful this exchange meeting was.

Li Chong's unconventional approach, it is not an exaggeration to say that he is a ghost.

It's a hardship for the students of Guozijian, because Li Chong is doing this, and it will be impossible to study or not in the future.

Even......

In the future, we may have to rewrite the textbooks.

Of course!

That's for later.

Since then, from the heirs of second- and third-rank officials to the seventh and eighth ranks, almost all the officials and nobles in Chang'an City of the Tang Dynasty have known Li Chong.

In fact, they knew each other before, but they didn't know each other well enough, and now, they seem to finally know why His Majesty wants a man who is only twenty years old to teach the prince.

Because this person is really a bit perverted.

And...... If he was so good at arithmetic, then wouldn't be the others.

After Li Chengqian returned to the palace, he spontaneously publicized to Li Chong how powerful he was.

Hearing this, Empress Changsun couldn't help but be curious.

Of course, Li Lizhi was very depressed.

That's why I want to learn arithmetic.

Now, she seemed to understand why.

It's all Li Chong!
