In order to promote Arabic numerals during the Zhenguan period, Li Yuanjia really spared no effort.
And he can't be lying. After all, if you want to understand the principle of "assembly line", you really need to know some mathematics... Of course, you can also figure it out using the mathematics of your ancestors, but it's not as simple and direct as Arabic numerals.
That's all.
But Cheng Zhijie naturally didn't know the twists and turns here.
The old man just knew that King Han told him with a serious face that he must learn mathematics first, and then he could master the method of making it quickly and cheaply, so it must be true.
He is a prince, so there is no need to deceive him into being a prince.
So after pondering for a moment, the old man asked: "Then I would like to ask your Majesty, if I want to send someone to learn this...mathematics, right? If I want to learn this, is there any way?"
When he asked this question, Cheng Zhijie also narrowed his eyes.
What method?
This is just a superficial statement. In fact, I want to ask what conditions King Han wants to offer.
The law should not be taught lightly, he understood this.
Now is the twelfth year of Zhenguan in the Tang Dynasty, an era where there is no patent law, but knowledge is equally valuable.
Why are there so few scholars? Because in addition to expensive pens, inks, paper and inkstones and the sky-high price of books, the cost of studying with a teacher is also quite scary. Ordinary families should not even think about it. Even a small wealthy family wants to support a scholar.
Just tighten your belt.
If you have to find a comparison, the tuition fees in ancient times should be the standards of private schools in the future, or even higher.
Reading is like this, and studying art is no exception.
Whether you want to be a blacksmith, a carpenter, a mason or a paper craftsman, you usually have to work as an apprentice with a master for a few years... In fact, you work as a free laborer, and then you can slowly learn some real skills. Even so
, the masters often have to leave behind a skill or two to keep the bottom of the box, passing it on to their sons but not to their daughters, from within to within but not to outsiders...
This is the reality, so this is why Cheng Zhijie asked tentatively.
If it were an ordinary craftsman or someone else, he certainly wouldn't need to be so careful, but in front of him was the King of Han of the Tang Dynasty, a person with a higher rank and title than him. Duke Lu could only ask the question sincerely.
And before asking these questions, he was also prepared to be rejected.
It is not easy to spend money to buy technology these days, especially a magical technology like King Han, which is even more difficult. So Cheng Zhijie asked casually out of curiosity, and it was not surprising that he was rejected.
However……
"Want to learn math? It's easy!"
After looking at Cheng Zhijie, Li Yuanjia said with a strange expression: "The Xinhua Bookstore in Dongshi sells a complete set of books. The price is not expensive and you can buy them anytime. Of course, that set of books is just a foundation.
, but after you finish learning, you can follow my people to learn the rest, and the speed will be much faster!"
When he said this, Li Yuanjia paused for a moment, and then continued with a smile: "Haha, speaking of it, Li Tai has already completed the entire set of books. He is the first person to... ahem, the first person to complete mathematics.
ah!"
"Li Tai? King Wei?"
After hearing what Li Yuanjia said, Cheng Zhijie's expression suddenly changed.
King Li Tai of Wei, the emperor's second legitimate son, is also a popular figure in the court today. Even he has learned mathematics? And he has already finished it?
"Eh? That's not right!"
Just as his heart was shaken, Cheng Zhijie suddenly remembered the previous words and was shocked again: "Your Majesty, are you saying that those books can be bought in bookstores? You can read them just by looking at them?"
"Yeah, it's easy."
Li Yuanjia nodded, feeling quite proud.
Very simple basic mathematics knowledge, basically the content of elementary school, seems to be a little bit in junior high school? What Li Yuanjia is most proud of is that he spent several years of hard work, slowly polishing it into something that can be learned by self-study
The level of understanding may not be as reasonable as the future planning textbook, but without the guidance of a teacher, it should be the most suitable for people of this era, right?
Therefore, this set of books will definitely be despised by literati because it is too straightforward and the text has no aesthetic feeling at all, but it will definitely be much easier to learn than mathematics books written in ancient Chinese.
What others can write in one book, Li Yuanjia used six whole books!
"Gudong!"
Seeing his proud look, Cheng Zhijie swallowed subconsciously and didn't know what to say for a moment.
Isn't he a prodigal?
It's okay if you don't hide such a good thing, but you actually put it directly in a bookstore for sale? How much money can you make from a set of books? The money is always overwhelming, right? Not to mention that people will buy it after they buy it.
Wouldn’t you make a few copies for yourself and then sell them to others?
If he knew what this big boss was thinking, Li Yuanjia would definitely laugh out loud!
Take it and copy it?
This is really not surprising. After all, the distribution of books these days is mainly based on copying books. Printing and other things are really too expensive. Ordinary readers may not be willing to spend money to buy them.
But was Li Yuanjia afraid of others copying those six mathematics books?
What he is afraid of is that no one will watch!
If he hadn't been afraid of breaking the rules or attracting people who were greedy for petty advantages to take it casually, Li Yuanjia would have thought of printing 10,000 copies and distributing them for free in Chang'an and Luoyang cities.
So if someone dares to buy it, copy it, and then resell it, Li Yuanjia will not be angry, but will laugh three times. As long as they can sell it, he will even secretly fund the pirates hundreds of dollars.
question!
Anyway, seeing that Cheng Zhijie was a little moved, Li Yuanjia struck while the iron was hot: "Lu Guogong, if you want it, I will send someone to send you a few sets later, haha. You can find a few more people to learn from it. If you have difficulties then, I will
I can also send someone to give them a class and explain something... Well, after they finish studying these books, I will have someone teach them how to speed up the manufacturing of overturned cars and reduce the cost. That will be much easier.
Got it!"
After saying a series of words, Li Yuanjia's attitude was quite eager.
But what he didn't know was that his enthusiasm scared Duke Lu!
This King of Han...
Are you sick?
He was rushing to show off his unique skills, as if he was very eager and very happy?
To be honest, Lu Guogong was really confused at the moment.
Almost as a conditioned reflex, Cheng Zhijie immediately felt a sense of uneasiness in his heart, and he was a little hesitant about letting others learn from him.
It’s not the business that’s catching up!
Don't think that Lu Guogong is a bitch, Li Yuanjia's attitude is really contrary to common sense. If he behaves in a difficult manner, or if he opens his mouth like a lion, Cheng Zhijie will think it is normal. However, this reaction is really unexpected, which makes the mature and steady Cheng Zhijie
Somewhat uneasy.
"Could it be that...there's something wrong with this?"
