President of Datang [Transmigration Book]

Li Jiang stared dumbfounded at the two holding hands in front of him, and for a moment he didn't know whether to continue arguing with Zhu Xieli, or to ask Li Tan if he had a better algorithm.

Li Tan withdrew his hand unnaturally, always feeling that the place touched by Zhu Xieli had become a little strange.

Zhu Xieli didn't mind either, he just tilted his head to look at him and asked, "Does Sanlang have a better algorithm?"

Li Tan took a look at the problem they were discussing, and found that it was a famous hundred-chicken problem in history. The specific topic was: Today, there is one rooster, and five money; one hen, three money; three chicks, three money one.If you buy a hundred chickens for a hundred dollars, how much are the chickens, mothers, and chicks?

To be honest, Li Tan saw that this question is too big. Anyone who has studied mathematics should be familiar with this question. This is a question about an indeterminate equation.

If you want to explain it, Li Tan can solve it. Even if he can't solve it, he can find the corresponding answer in the reading system. Then the question comes, how can we explain it so that these two people can understand it?

In the end, Li Tan decided not to use the simplest algorithm of later generations. After all, that algorithm involved too many mathematical theorems of later generations, so he could only try his best to make these two people understand.

In the end, Li Tan chose the algorithm in "Hundred Chicken Shu Yan". After all, Xie Chawei's previous algorithm was more of a conjecture, not particularly correct, and Luo Tengfeng's method of seeking one is not as good as it seems. equation method.

Li Tan directly picked up the pen and paper while writing and drawing, and said: "We need to use the equation method here. First, we set everything to be zero."

Li Tan was explaining while talking. To be honest, the equation method is actually very close to the equations of later generations. The only difference is that it is more troublesome to write.

However, at this time, the concept of equations already exists, but it is not particularly certain whether the equation method will appear or not.

What's more, this is a world of romance novels. Although the world has been completed by itself, Li Tan is still a little worried.

He finished the whole topic with apprehension.

After he finished speaking, he looked at Li Jiang and found that Li Jiang was looking at him blankly, with words written all over his face: What are you talking about?What did I hear?

Seeing him like this, Li Tan knew that he didn't understand, and couldn't help turning his head to look at Zhu Xieli hopefully.

Zhu Xieli's expression was also a little hesitant, and he could understand a little bit at the front, but at the back...he knew how to write every word Li Tan said, but when combined...it seemed...he didn't understand a single word.

But facing Li Tan's expectant eyes, Zhu Xieli had no choice but to ask humbly: "What is the method of breaking the whole into parts? Why haven't I seen it before?"

Li Tan searched for a moment, and then found... This thing is a question raised in Mei Wending's "Equation Theory" in the Qing Dynasty.

Li Jiang on the side was also very skeptical: "That's right, I haven't heard of it either."

Li Tan had no choice but to express in great pain: "This... I just said it casually, but this method is correct."

Li Jiang looked skeptical: "Impossible, Li Taishi didn't figure out the problem, how could you figure it out?"

Li Tan turned around in his mind before realizing that the Li Taishi Li Jiang said should be Li Chunfeng, a mathematician in the early Tang Dynasty. When he died, he was restored as Taishi Ling by Emperor Gaozong Li Zhi, so when people call him, they will call him Li Taishi.

After thinking about it, Li Tan already wanted to flip the table. Are these two brats well fed?

Let's discuss here the questions that Li Chunfeng can't answer, and want to fight for a Zichou Yinmao?You deserve a beating, right?

Seeing Li Tan's unkind expression, Zhu Xieli immediately said, "I don't quite understand, can you lend me your problem-solving paper first? If I don't understand something, I'll ask you later."

Li Tan nodded, handed him the paper, and simply regarded Li Jiang as air.

After all, the background has fully shown the status of these two people - he just said for a long time, playing the piano to Li Jiang is like playing the piano to Niu Niu, and the value of master and apprentice has not increased at all, but Zhu Xieli has also increased him a little, which shows that Zhu Xieli At least I understand part of it.

Li Tan was very pleased with this, after all, it was the male lead, and the IQ of this group of cannon fodder was not on the same level as him.

But before Li Jiang could ask any more questions, Dr. Chen walked in.

Li Tan originally thought that the discussion of this math problem would end here. Although it was a bit of a scam, he provided him with a little mentoring value, and not much is better than nothing.

However, he never expected that Li Jiang has a big mouth!

When Li Tan came to Guozixue the next day, he saw Zhu Xieli surrounded by a group of people.

When he saw it, his heart tightened instantly, and he was really worried that blood would splash on Guozixue again. Is it true that these people don't have a long memory?

Li Tan hurried over, only to find that the people around Zhu Xieli were all unfamiliar faces, and couldn't help but feel even more strange—could they be students of Taixue?

Although surrounded by people, Zhu Xieli's height was absolutely superior to the audience, and he spotted Li Tan's figure almost instantly.

I don't know how he did it, but in three or two steps, he broke free from the crowd's siege, and walked towards Li Tan.

And the people who were talking around Zhu Xieli just now were all confused, no one knew how Zhu Xieli got out!

After reacting, these people quickly caught up with Zhu Xieli.

At this time Li Tan had already met Zhu Xieli, and only then did he realize that the expressions on the faces of those chasing Zhu Xieli were a little anxious, but there was no hostility, so he couldn't help asking: "This is... what happened?"

Zhu Xieli hesitated before saying, "They want the calculation paper you wrote yesterday."

Li Tan froze for a moment, then looked at these people, and those people looked at Li Tan quite surprised.

There is no other reason, Li Tan is too young, even young, and this group of people are at least twenty years old, doesn't Li Tan look like a child in front of these people?

Before Li Tan could speak, a Confucian scholar who was not well-dressed among the group saluted and said, "I'm studying Chu Shurong and have met His Royal Highness King Jianning."

When he saluted, the others also saluted sparingly, and said in unison: "I have seen His Royal Highness King Jianning."

Li Tan hurriedly returned the salute, after all, these days the emperor had to salute relative to the ministers, this is the courtesy to the scholar-bureaucrats, let alone a little county king.

After Li Tan returned the gift, he asked a little late: "Everyone... are you here for the question of the chickens?"

Chu Shurong's face is ordinary, but his temperament is very special. He looks like a researcher. After hearing Li Tan's words, he nodded and said: "I was very excited to hear that His Highness solved the problem of chickens yesterday, but it was too late to come. I came here to ask for advice, so I took the liberty to come here today, and I ask Your Highness to give me some advice."

Zhu Xieli frowned while listening, he stopped Li Tan who was about to speak and said: "King Jianning may have to discuss this matter with the doctors before he can figure it out. I won't give it to you if you want it now, everyone. Please come back."

Li Tan was taken aback for a moment before realizing that impartiality is not practiced these days. No matter who has some skills, they usually choose to inherit from their own family or accept apprentices, and will not hand over their own things easily.

After all, this is a housekeeping skill. The disciples of the church may starve to death of the master, so how can they teach these people who have never been masked?

It's just that Li Tan doesn't mind too much, and even wants to spread it. After all, if there are more people who study the chicken problem, and they all study his algorithm, it can promote the development of Datang's mathematics. Can harvest a large number of mentoring values.

But he still didn't speak, and let Zhu Xieli politely send these mathematics students away in front of him.

After these people left, Zhu Xieli sneered and said: "These people have bad intentions, don't be fooled by them."

Of course Li Tan understood what he meant. If he really wanted to learn, then he shouldn't make such a gesture, but came to ask for advice seriously.

He ran to argue with Zhu Xieli, didn't he just hope that he would not be released from Li Tan?When the time comes, it will really be solved, and whoever spread the word to solve the problem may not be sure.

Students of Guozijian's computing science will inevitably be confused by the false name.

Li Tan accepted Zhu Xieli's kindness and said, "Okay, I understand."

Zhu Xieli put away the indifference just now, turned around and said: "I did the math yesterday, and your method is indeed correct, but there are many things I still don't understand about that method."

Li Tan looked at Zhu Xieli's look of expectation, and thought of the complicated way of solving the problem, he couldn't help but feel very headache.

However, for the sake of master and apprentice, he still nodded and said: "Before the doctor arrives, let's find a clean place to study."

Zhu Xieli took Li Tan directly to the remote stone table instead of choosing a classroom.

Zhu Xieli sat down next to Li Tan, because it was too close, Li Tan could even feel the heat from Zhu Xieli's body and the faint fragrance from his body.

Li Tan couldn't help but sniffed and said, "What kind of incense did you use, it smells so good."

Zhu Xieli directly untied the sachet from his waist and said, "This spice formula is my aunt's family secret recipe, so I can't give it to you. This sachet is for you, and I'll give you two more later."

Sending the sachet... There is no misunderstanding between the two men, but Li Tan's ears turned red for a moment, and he quickly returned the sachet to Zhu Xieli and said, "I just said that, you What are you doing?"

Zhu Xieli didn't force it and just said: "This sachet is a bit old, I will send you a new one later."

Li Tan really didn't want to entangle with him about the sachet, so he quickly asked, "What don't you understand?"

Zhu Xieli listed out the problems he didn't understand very clearly, and Li Tan knew at a glance that these problems were not researched in this era, so he had to explain to him very headache.

However, this explanation is actually not the same as expressing how things such as equations are derived.

Li Tan actually knew that these things should not be said, and these things should not appear now. However, he looked at the master-student value that Zhu Xieli kept providing him, and he was a little selfish, thinking that he would only talk to Zhu Xieli. It's time to let Zhu Xieli keep it a secret.

Zhu Xieli has turned his back on the sun without mentioning one thing, and his character is still good.

However, halfway through the discussion between him and Zhu Xieli, when he had just finished talking about the meaning of equations and the classification of linear equations, and was about to continue the following topic, he suddenly heard someone behind him shout: "Okay!"

Li Tan was taken aback immediately, and when he turned his head, he saw a dry old man with a goatee, his eyes gleaming, and he was bending over to get into the gap between him and Zhu Xieli.
