Chapter 86 Sir, I know as many words as eight palms

Beiping City, Cheng Family Courtyard.

The children were standing on tiptoes, grabbing the window sill of Cheng Nuo's office and peering in. Because they were of different ages and taller and shorter, some could see, while others were anxious.

Seeing this, Wen Cong lifted up his sister and asked her to stand higher. Now that the injury was completely healed, he said, "Hui Hui, can you see clearly now? Have you seen that thing that your husband often takes?"

"

Goudan'er made some saliva and wiped the window brighter: "Sister Wenhui, you have to read the name of the book clearly. When the time comes, we will save money and go to the bookstore to buy a copy, and then we can all read it together."

Nidan'er leaned against the wall, with a lack of interest on her face: "How come you don't believe it? There's no secret to why Mr. is so great. It's because he has read more books, and the more he knows, just like our teacher said

In that way, the meaning of the book will become apparent after reading it a hundred times.”

Goudan stared, and tapped his sister on the forehead with his finger: "You are the only one who knows a lot, so next time the teacher punishes me for copying, come and help me. You can learn more."

Nidan quickly wiped the area that was touched: "It's so dirty. I won't tell my mother when she comes back to see me. Anyway, it's wrong to peek at your husband's things."

Goudan'er was unconvinced: "Who said it was stolen? We just want to take a look. If we file a complaint, we will eat the candied haws regardless of you."

Seeing that Cheng Nuo's room was closed, these children had no chance to go in on weekdays, and they were all as powerful as Mr. Cheng. They thought that there must be something powerful in the room, just like the treasure in the play, and their intuition told them that it was

A book that Cheng Nuo often takes.

So out of a child's mentality, I wanted to see what was going on through the window. I didn't have the guts to steal, but I still had the desire to save my pocket money. If it didn't work, I could still sell newspapers, push carts, shine shoes, etc.

There is a way to save slowly.

"Brother, I saw it clearly. The name seems to be "Mathematical Dictionary". Have you heard of this name?" Wen Hui felt sorry for her brother and wanted to come down quickly after speaking.

Wen Cong carefully put his sister down and asked: "Are you sure you read it correctly? Is it called "Mathematical Dictionary"? It seems that I have never heard of this name. He must be right."

Goudan'er had only studied for a few days and didn't know much. When the two brothers and sisters said this, he immediately believed it in his heart: "Yes, it should be it. I will go to the bookstore tomorrow to ask and see how much it costs. In our hearts

It’s a good number.”

At this time, a familiar yet unfamiliar voice suddenly came from behind: "What are you doing? Did you see any good treasure? I'll take a look too."

As he said this, the man also lay down on the window sill and looked in through the window, looking very curious.

The children turned around and saw that it was Cheng Nuo himself, lying with them. They were frightened out of their wits.

"Sir, I'm sorry, I didn't know you were coming back, otherwise we wouldn't dare."

As the eldest brother and the "chief criminal", Goudan'er took the initiative to stand in front of his younger brothers and sisters, lowering his head and extending his hands, as if he was ready to be punished.

Cheng Nuo almost couldn't help laughing when he saw it. This was so familiar. He became so playful that he clenched his fists and raised them high, scaring the children so much that they closed their eyes tightly, fearing that a "tragedy" would happen.

Even Goudan'er, who had always been bold and bold, closed his eyes tightly when he saw this. He was not so scared when his own mother beat him.

But what he didn't expect was that the gentleman raised his hand high, lowered it gently, secretly opened a crack, and found a few small bumps wrapped in paper in his palm. They were colorful and beautiful, but they never

never seen it.

When my husband noticed me, he immediately raised his neck and closed his eyes tightly.

"Okay, Goudan'er, stop pretending and open your eyes. This is the candy I brought you from Shanghai. Try it."

Upon seeing this, the children immediately came over shouting and waiting for Cheng Nuo to share the candies with them. Their mouths were filled with sweetness and they felt much closer to their husband.

"How is it? Is it delicious?"

"It's so sweet, even sweeter than stove candy, thank you sir."

However, Cheng Nuo did not forget his mission. He led the children into the room and introduced the mathematics dictionary. He also said that when it is published in the future, he will give each of them a copy and encourage them to study hard. If they don't understand, they can come at any time.

Find him.

Watching the children walking away, Cheng Nuo picked up the dictionary in his hand. Although it was only a first draft, it was too bulky. It is a good teacher and helpful friend for professional mathematics practitioners, but for these students who are new to mathematics,

On the contrary, it is not conducive to browsing and reading. You may give up when you see such a thick stack.

I came to the front yard and found the temporary office of the School of Mathematics, where several people were compiling books.

"Come on, come on, thank you for your hard work. This is the specialty pear candy I brought from Shanghai. I have been very busy these days. Take it and share it."

Yan Jiazuo, who was still bowing his head while proofreading, raised his head and saw Cheng Nuo coming back. His face was full of surprise: "Dean?! When did you come back? You are almost missing us."

Ma Minghai, who was about to pour water, stopped immediately, ran over and said with a smile: "My dear dean, you still think that we still have a school of mathematics and science. I thought you ran away with your sister-in-law with the funds.

"

"Screw you, my wife is nowhere to be seen. Where is the sister-in-law? Quickly share the candy with everyone and shut your mouth." Cheng Nuo scolded with a smile and handed over a large bag of pear candy.

These two people were the key people he invited, and both had master's degrees. One was from the same school, Harvard University, and the other was from Columbia University. Their knowledge was very solid, and they often joked with each other when they got together.

We all have a good relationship in private, but when it comes to work, everyone is more serious than the other.

Cheng Nuo picked up the "Mathematical Dictionary" that had been proofread twice on the table, and after reading it for a while, he said: "Everyone did a good job, especially the brief review of the history of mathematics at home and abroad at the end, which made me very happy.

Surprisingly, I have reached the point where I can contact the publisher.”

Yan Jiazou said solemnly: "Dean, I think our examples are not clear enough. I plan to streamline them later, and strive to include detailed explanations or proof processes behind each important knowledge point."

Ma Minghai followed up and said: "Yes, in addition to what Lao Yan said, I am also going to add some famous mathematical conjectures that have been proven or unsolved, such as your Kronecker Youth Dream. I am also thinking about how to use it to solve the problem.

The form is integrated into it.”

"Kroneck's youthful dream can be put into the number theory section. Just talk about it briefly. There is no need to elaborate on this." Cheng Nuo sat on the seat, put the book on his lap, and said with a smile: "But in this way

, I am afraid that our "Mathematical Dictionary" cannot be put down, and it will have to be renamed "Mathematical Dictionary". Just a few of us here may not be able to complete it in a year or two."

"So what is the dean's opinion?"

"My opinion is that you don't need two books if you can fit them in one. The name is changed to "Concise Mathematics Dictionary". Just like its name, it only needs to introduce its concepts in easy-to-understand language. If readers want to learn more about it, they can

Just add the name of the professional book on the side."

"But in this way, the heaviness of our book will be greatly lost, and I'm worried that the effect may not be good."

Cheng Nuo slid down from the table and said: "On the contrary, it should be less heavy and more popular. Remember that our books are used to lower the readers' threshold for learning mathematics, not to increase troubles, not to mention how many.

Even a few pages of running characters cannot replace professional books."

Under its arrangement, the work of "Concise Mathematics Dictionary" has been simplified. The main target audience is primary and secondary school students. The content includes arithmetic, algebra, plane geometry, solid geometry, plane trigonometry, plane analytic geometry, space analytic geometry, probability, statistics,

There are more than 2,000 common terms in logic, algebra, etc.

And considering that many students may drop out of school, we simply added a chapter on abacus, with its mental formulas. As long as he is literate, he can slowly get started with those few pages and gradually master the abacus.

Craftsmanship that allows him to eat.

However, in this way, although the overall content needs to be overhauled, the main work is to streamline it, and it is actually much faster than before.

After giving the plan, Cheng Nuo was about to leave the courtyard when he happened to bump into Li Laosan.

I haven't seen him for a while. Li Laosan's face has darkened a lot, but he seems to be in better spirits.

"Sir, when did you come back? Why didn't you inform me? I'd also like to pick you up at the Qianmen train station, asking you to travel such a long way."

"Hey, Lao Li, I sent you a telegram and you didn't recognize it. It's better for me to walk back by myself to save worry and trouble." Cheng Nuo waved his hand and said casually, it's just a short journey, just take a taxi and come back.

There's no need to send a special telegram. You're charged per word, so it's not much less than the fare of a car.

After hearing this, Li Laosan smiled honestly: "Sir, I actually know a few words. If you send another telegram, I will definitely know them."

Cheng Nuo was surprised and said: "Okay, I've been away for three days, Lao Li, so you want me to treat you with admiration. Come on, come on, I'll test you, please write me your name."

Seeing this, Li Laosan enthusiastically picked up a piece of rubbish in the yard and wrote his name on the ground.

Although the handwriting is crooked, the three characters "Li Laosan" are vaguely visible. It seems that he can really write his name.

Seeing this, Cheng Nuo couldn't help but punch him in the chest: "Old Li, you are really good. When I go out again, can you give me another surprise? Tell me how you learned how to do it.

"

Li Laosan threw away the dirt, patted the dirt on his hands and smiled honestly: "Didn't you say before you left that I could be a teacher if I was good at farming? I thought there was no reason for a teacher to be illiterate, so I hired someone.

Taught slowly."

He clapped his fingers and rolled his eyes up to count. Li Laosan smiled and said, "I know how to use eight palms now. I will continue to learn later."

Through his smile, Cheng Nuo saw the green and black wheat seedlings in the yard. They were thick and powerful, with well-developed root systems. They were obviously as energetic as their owners.

This man, if he has hope, his life will be different.

"Mr. Li, let's go to the Commercial Press!"
Chapter completed!
