Wang Lei looked confident, and said unhurriedly: "Yuan Zhuogong has already said the final result, if I talk about the result, it is obviously meaningless." That being the case, prepare the pen, ink, paper, and inkstone, and I will tell you how to answer this question. ”

"Someone, prepare pen and paper!"

Zheng Xuan ordered, stood up and said, "Little friend, sit here with the old man, and the old man will see how you calculate." ”

Wang Lei got up and walked to Zheng Xuan's side and sat down without concessions.

Xun Chen's eyes widened, and his heart was pounding and jumping. His heart beat faster and he directly thought that it was difficult to end the matter. Xun Chen was anxious, but Wang Lei was in the chest, and Xun Chen could only wait and see.

After a short time, the scholar brought a pen, ink, paper, and inkstone and placed it on the stone table.

Wang Lei took the brush and wrote:

Solution: If there are x lamps on the top floor of the tower, the equation can be listed:

x+2x+4x+8x+16x+32x+64x=381

Solve x=3

A very simple equation is solved, and the final answer is directly obtained.

However, Wang Lei can understand this equation, Zheng Xuan, Liu Hong, Xu Yue and Xun Chen who was sitting next to him were in a fog and didn't understand what was going on? Especially the strange symbols written by Wang Lei made several people even more inexplicable. can see that Wang Lei has a pretentious appearance, and the answer he finally came up with is the same as Liu Hong, like that.

Suddenly, Liu Hong's eyes lit up and said: "This painting is vigorous and powerful, Your Excellency is Wang Zhoumu?" ”

Wang Lei smiled: "It's exactly below!" ”

Zheng Xuan arched his hand and said: "Zheng Xuan, the man of the mountain village, meet the adults!" ”

There was a hint of respect in his tone.

Wang Lei said: "Kang Chenggong is polite, it is very good that you can come to Jizhou, you don't need to salute." ”

Wang Lei's solution just now made Zheng Xuan very curious.

Zheng Xuan went straight to the point and said excitedly: "Can Lord Wang explain, what is going on?" How is it calculated. Just a few simple words, with a bunch of strange symbols, how to figure it out. ”

Historically, China has had a multiplication table of "Ninety-Nine Songs" very early.

However, the multiplication table for the "Ninety-Nine Songs" is an oral transmission and does not record how it was written. As with many Chinese skills, they were passed down orally from beginning to end, with no clear canonical records. There are no punctuation marks such as addition, subtraction, multiplication, and division, and there is no punctuation even in the articles that are read. More attention is paid to reading a book a hundred times to see its meaning, so that those who read read more books and gradually understand its meaning.

After Zheng Xuan, Liu Hong, Xun Chen and others saw it, they didn't understand what was going on.

Wang Lei scratched his head, and after organizing the wording, he briefly talked about the plus, multiplication, division and equations. After finishing speaking, Wang Lei elaborated carefully again, so as not to make Zheng Xuan and Liu Hong unable to understand.

Rao is like this, Zheng Xuan and Liu Hong are still confused.

Wang Lei elaborated several times in a row, and the doubts in the eyes of the two of them were slightly alleviated, but they didn't really understand. Zheng Xuan is a person who likes to explore, and said: "After listening to Wang Zhoumu's words just now, punctuation, as well as addition, subtraction, multiplication, and law, have a complete system. Please ask Lord Wang to write a book and publish it again. In this way, all the people who read in the world benefit from it. ”

Wang Lei had a flash of inspiration in his mind and said: "Kang Chenggong, for the sake of the world's readers, I am indeed willing to write books and speak." But if I were in charge, I would spend very little time writing books and not much to do. I'm afraid it will take a few years for me to come up with a complete system. I don't think it's better to do this, so I'll hand it over to Kang Chenggong and Yuan Zhuogong together, and you guys will compile it, isn't it better? ”

Zheng Xuan hurriedly said: "No, no, this kind of thing, how can you let the old man take away your reputation." Once I compiled it, the world thought that this was my idea, but this was Wang Zhoumu's whimsy, and I couldn't rob Wang Zhoumu's reputation. ”

Liu Hong said: "I also agree, Wang Zhoumu is personally responsible for this matter." ”

Wang Lei shook his head and said: "Kang Chenggong, I have more energy on Jizhou, busy with government affairs, and I really don't have enough time." You are a scholar, and it is fitting that this matter is entrusted to you. Don't shirk it, there is a standard for the whole set of symbols in the mathematical system, as well as some of the symbols that I wrote in my handwriting. These are very energy-consuming, and they need to be escorted by a great Confucian like Kang Chenggong, with Kang Chenggong and Yuan Zhuogong together, I can rest assured. ”

"Isn't that ......?"

Zheng Xuan thought about taking Wang Lei's reputation, and he was reluctant. He is an old man in his sixties, and once he does it, the world will definitely think that he did it.

Wang Lei nodded and said, "Master Zheng doesn't like fame and fortune, and he doesn't like power, so at this time, he is calculating." This is conducive to reading and learning characters, and is conducive to the increase of knowledge for future generations, so why should we shirk it? ”

"Lord Wang is open-minded, Zheng Xuan admires."

Zheng Xuan saluted respectfully, his eyes excited.

Immediately, Zheng Xuan looked at Liu Hong and said, "Yuan Zhuo, you and I are the same age, and we are also in our early sixties, so there is not much time to delay." It would be better for the resignation to compile the book with me and lay a foundation for future generations. ”

Liu Hong frowned, he was the Taishou of Shanyang County, and he was going to resign......

This hesitation, Zheng Xuan also had a straight face.

Zheng Xuan flicked his sleeves and said coldly: "Well, since Yuan Zhuo is unwilling to give up his power, the old man is not reluctant, and I will compile it by myself." Without you, the old man can't finish his faith. ”

Liu Hong smiled bitterly: "Brother Kang Cheng, what are these words?" Did I say I wouldn't help you? Anyway, it's time for me to retire at this age. I will first go back to Yanzhou and resign from the post of Taishou of Shanyang County, and then I will assist you in compiling books. ”

Zheng Xuan said directly: "It's really troublesome, isn't it solved with a letter?" ”

Liu Hong shook his head and said: "People have to do what needs to be done, and they can't go perfunctory." ”

Zheng Xuan nodded helplessly and said, "It's okay, whatever you want." ”

Wang Lei was happy in his heart, Zheng Xuan and Liu Hong wanted to study punctuation, etc., and they would definitely stay in Ye County. In this way, Ye County has a great Confucianism and can become a holy place for scholars. Wang Lei looked calm and said, "This matter is not in a hurry, take your time." When Kang Chenggong first came to Ye County, if he needed anything, just ask, or go to the state pastor to find me. ”

Zheng Xuan said: "Wang Zhoumu, on the issue of symbols, I have to ask Wang Zhoumu for more advice. In particular, the algorithm that solved the lighthouse problem just now is very interesting and needs the guidance of Lord Wang. ”

Wang Lei said: "I will tell Kang Chenggong about this as soon as possible, so that you can compile it." ”

With a good start, Wang Lei directly won the approval of Liu Hong and Zheng Xuan. The two talked with Wang Lei and had a great time. This scene made Xun Chen stunned for a moment, looked at Wang Lei's eyes, and felt that Wang Lei was a mystery. What talent has not yet been revealed to this young lord?

Verse! Font! Arithmetic!

All three of these are very powerful, what will be the talent next time?
