It was a good thing that Lao Zhu wanted to read it. The next day Han Du rushed to deliver the three basic sets of books to Lao Zhu.
Finally, I did not forget to remind you, "Your Majesty, you can read more about mathematics. Learning mathematics can improve people's thinking, which means it helps to keep a clear mind. You can also read about physics and chemistry, but your Majesty, please do not do experiments by yourself." . Some experiments are full of dangers. If the emperor is harmed, I will be in trouble."
Hearing Han Du's reminder, Lao Zhu nodded happily.
A few days later, Lao Zhu summoned Han Du into the palace again.
Han Du saw Lao Zhu, whose eyes were a little red, sitting on the dragon chair with a tired look on his face. He couldn't help but be a little surprised. What on earth is going on?
"Your Majesty, are you okay?"
Lao Zhu had a fighting spirit in his work. In eight days, Lao Zhu reviewed and approved a total of 1,660 memorials from internal and external departments, and handled 3,391 national affairs projects. On average, he had to review memorials every day. He wrote more than 200 letters and handled more than 400 state affairs. And it has been like this for many years. Although the memorials on weekdays cannot be as many as these eight days, the perseverance is enough to be daunting.
At this point, Lao Zhu didn't show any signs of fatigue.
"I'm fine." Lao Zhu took a deep breath, trying to relieve his body's fatigue and make him more awake.
"Your Majesty, what's wrong with you?"
Lao Zhu shook his head and said: "It's okay, I just read these books and I was fascinated by them. Especially the mathematics, the writing is really good, step by step, from easy to difficult."
Although Lao Zhu looked satisfied, an idea suddenly came to Han Du's mind after hearing this. Could it be that the reason why Lao Zhu is so tired is related to mathematics? He won't study the exercises in the book, right?
If this is the case, then the culprit that made Lao Zhu exhausted may be revealed.
"Your Majesty, have you finished reading this mathematics book?" Han Du was a little surprised.
When Lao Zhu heard this, he smiled awkwardly and said, "No, it's still a little bit worse. I only saw the equation part."
Well, after hearing what Lao Zhu said, Han Du probably understood why Lao Zhu became like this. He must have seen the equation
The problem of solving the category must be stubbornly stuck with the question.
"After reading this equation problem, I realized that the mystery behind it is not simple. Now that I have learned this mathematics, the more I understand it, the more I feel how amazing and impressive Han Jingyun's proof was at that time. Look up." Lao Zhu praised from the bottom of his heart. You must know that Lao Zhu is a person who thinks very highly of himself. Whether it is culture or martial arts, he thinks he is the best in the world.
At the beginning, he was obviously the weakest, but he completely looked down on Chen Youliang, Zhang Shicheng and others. This shows how open-minded Lao Zhu is. But now even he has to be impressed by Han Jingyun's wisdom.
Mentioning Han Jingyun, Lao Zhu couldn't help but curiously asked: "By the way, I want to ask you, and you have to answer me truthfully. How high is Han Jingyun's mathematical attainments?"
How high exactly? That's just ridiculously high, okay?
Han Du didn't know how to answer Lao Zhu. After hesitating for a long time, he had no choice but to bite the bullet and reply: "I don't know about this either."
After hearing this, Lao Zhu said with a dissatisfied look: "I asked you to tell the truth, so you tell the truth. Although I am the emperor, I have never thought about being the first in everything. I am born to be poorer than those wise men when it comes to learning. I know this very well. There are many people in the world who are more knowledgeable than me. Did I say anything?"
Seeing that Lao Zhu misunderstood, Han Du quickly explained with a wry smile: "Your Majesty, it's not that I dare not say it, but that I really don't know what level of attainments she has achieved now."
Seeing that Lao Zhu was confused, Han Du could only sigh and pointed at the basic mathematics in front of Lao Zhu and said: "Take this mathematics book as an example. How long did the emperor think it took her to finish it?"
Lao Zhu smacked his lips and felt that he had not finished studying for five days. Even if Han Jingyun learned faster than him, the three days should be about the same.
"Three days?" Lao Zhu asked tentatively.
Han Du stretched out a finger, which shocked Lao Zhu.
"One day, to be precise, it only took her half a day to not only learn the basic mathematics, but also to master it."
Lao Zhu's face suddenly darkened, and he looked a little worried. He originally thought that with his talent and intelligence, even if
Not as good as Han Jingyun, but not too bad. But I never expected that they were not on the same level at all.
Han Du saw that Lao Zhu's face was not good, so he couldn't help but hurriedly explained: "It is rare to be able to learn the emperor's martial arts in such a short period of time."
After hearing this, the anger on Lao Zhu's face did not dissipate. Instead, he looked at Han Du unkindly and said, "Listen, why do you think you are scolding me?"
Han Du waved his hands in fright, "No, no, I definitely don't have the guts. Your Majesty doesn't know something. For ordinary people, it would take them several years to learn basic mathematics. Even I, at the beginning, could barely finish it. It took several years of study to finish it.”
"Is this really the case?" Lao Zhu was doubtful.
Han Du quickly said: "If the emperor doesn't believe it, why not find a few people and give it a try."
"Okay, I believe you." Lao Zhu finally believed Han Du's words, and then thought that he could learn in a few days what others took several years to learn, and a huge feeling of satisfaction suddenly emerged in his heart. feel.
"But how high is your sister's mathematical attainments?" Lao Zhu was still curious and asked unwillingly.
Han Du pondered for a moment and then said: "I really don't know, but after basic mathematics there are elementary mathematics, secondary mathematics and advanced mathematics."
"Oh? Does Han Jingyun belong to the advanced mathematics level now?"
Seeing Lao Zhu's curious face, Han Du shook his head and said, "No, she has already finished advanced mathematics."
"That's after advanced mathematics?" Lao Zhu couldn't help but widen his eyes. Only those who have studied mathematics can vaguely understand how difficult the string of mathematics Han Du said is.
"There will be no more advanced numbers after that, because there is really no way to divide them. How far she can go depends on what she wants to study." Han Du spread his hands and sighed: "This is why I have no way of knowing her. , the reason why it has reached that point.”
Lao Zhu was silent for a while after hearing this. He was originally curious about how far Han Jingyun had learned, and thought it would be nice to have a goal. Unexpectedly, he couldn't even find a target, and he couldn't even look up at Han Jingyun's figure.
