The first and second volumes of "Mathematics" are both priced at 300 yuan, which is quite mediocre.
Not too low, not too high.
Li Yuanjia has no intention of challenging the book pricing power of this era, so even if he uses ordinary paper and the cost is much cheaper than the paper used in Xinhua Bookstore, the final price is still not cheap.
So if anyone is interested, he really doesn't mind giving away more.
Not to mention a mere twenty sets of books, if someone is really interested in mathematics, even three hundred sets will be given away... No, Li Yuanjia can be sure that if the Tang Dynasty dared to set mathematics using Tianzhu numerals as a "compulsory course",
He is even willing to spend all his money to ensure that all students in the world have one!
However, I can only think about it, the possibility is very slim.
Sometimes Li Yuanjia also thinks about whether he can think of a way to change the horizontal layout to a vertical layout, at least from right to left.
But after struggling a few times, he gave up the idea.
Let’s not talk about how much convenience of Arabic numerals is left in this way, but one thing Li Yuanjia is sure of is that what really needs to be changed is not his own writing method, but the inherent concepts of literati.
Disaster!
It's hard!
So seeing the surprise on his princess's face, Li Yuanjia smiled and said: "Fengzhu, don't you think it's convenient for our palace to use these Tianzhu numbers for accounting and calculation? And the most important thing is that the people below
It may not be difficult to be greedy, but as long as you use it properly...hehe, at least it will be difficult to be greedy for big money."
"Well, yes."
As soon as the thought came to his mind, Fang Fengzhu immediately understood what he meant.
After learning Tianzhu numbers for the past few months, Fang Fengzhu also discovered the benefits of Tianzhu numbers, which are that they are very intuitive and can accurately record all expenses and income. If combined with various invoices designed by the king himself,
, selling bills and the like, it’s really not easy for the people below to fool around with things!
"How about... we can use it at home?"
As he was thinking about it, an idea suddenly came to Fang Fengzhu's mind.
Although Prince Han's Mansion is her so-called home now, she has only been married for four months and her habits have not changed yet, so Fang Fengzhu's first impression when she thinks of Fang Mansion is home!
Seeing Fang Fengzhu's thoughtful look, Li Yuanjia smiled slightly and didn't say much.
If you want to change something, the best thing to do is to start from around you.
Prince Han's Mansion is now barely on the right track. All the stewards have learned the Tianzhu numerals, and even the old antique Han Chengdu can barely use them. So Li Yuanjia's next goals are his father-in-law's Mansion of Liang Guogong and his uncle Yu Wenshi
It has reached the Duke's Mansion of the State of Ying.
Uncle Li Yuanjia is not in a hurry, he has the final say sooner or later.
Zen Master Yuwen, the eldest son of Yuwen Shiji and the former Sui Nanyang Princess, had been killed long ago, and his current wife is Li Yuanjia's clan sister. She only has one daughter, Yuwen Shutaro. The only thing left in the Yuwen family is Yuwen Shiji's concubine.
My younger brother and a concubine...
Anyway, Li Yuanjia knew based on his uncle's current health that he probably wouldn't be able to survive for a few more years.
Although it sounds a bit cold-blooded, in fact Li Yuanjia is really helpless, because even if he has certain guesses and inferences about his uncle's body, all Li Yuanjia can do is to formulate a healthier diet for him, and then strongly
I just suggest him to exercise more.
No matter how much, there is nothing you can do.
The only thing Li Yuanjia can do is to take good care of his elder sister and younger sister after his uncle leaves in the future, and it will not be too late to do something by then. The old man is at least sober now, and he wants to be with Duke Ying
Government promotes Arabic numerals...
Haha, it's a bit difficult.
So it is better to start with Liang Guogong's Mansion, which should be relatively easy. Firstly, Fang Xuanling is relatively more open-minded in Li Yuanjia's eyes, and secondly, with Fang Fengzhu here, the chance of persuasion is higher...
Just as the two of them were chatting and joking softly, Han Lucheng suddenly walked in in a hurry: "Your Majesty, your Majesty's decree has arrived!"
"oh?"
Li Yuanjia was slightly startled, and stood up suddenly: "Fengzhu, just read a book by yourself for a while. I'll be back as soon as I can."
After finishing speaking, Li Yuanjia quickly walked to the main hall and saw a young eunuch from the palace.
"Little Chen Li, I have met the king."
"Well, get up."
After waving his hand to ask the young eunuch to get up, Li Yuanjia glanced at him. The young eunuch quickly lowered his hands and said respectfully: "Your Majesty, your Majesty is scheduled to go hunting in Shiping on September 9th, and orders your Majesty to go with him."
"Hunting? Shiping?"
After hearing what the little eunuch said, Li Yuanjia was stunned.
Shiping is a place under Yongzhou, west of Chang'an, which he knows. Moreover, the distance is not too far, so it is not too hard to run there.
But going hunting?
Li Yuanjia's cheek muscles trembled twice, and his eyes instantly darkened. There is still war in the southwest border of the Tang Dynasty. More than 20 states have just experienced a severe drought. People in Bazhou have just rebelled and killed the governor.
With hundreds of other people, Lao Li still wants to go hunting?
unacceptable!
After receiving the order and waving Han Lucheng to send the young eunuch away, Li Yuanjia was still very panicked.
Selling hemp!
Of course he didn't pity the people who suffered from drought or war. After all, in such a big country and in this era, it was inevitable. What he was worried about was that it didn't matter if Li Shimin wanted to go hunting, but why?
Do you have to carry this burden of yourself?
I don’t know how to do that stuff. Aren’t you going to be embarrassed if you go?
Even though Li Yuanjia wanted to learn horse riding and shooting since he was a child, he only dabbled in it and never took it seriously. As for daily exercise, which seems to be very diligent, he just ran and ran according to his memory in his previous life.
I exercised other muscles on my body and touched the swords and guns in the martial arts field at home a few times just out of curiosity.
And horseback riding... I always ride in a carriage when I go out, okay?
and……
This is hunting, where you have to play with swords, guns and arrows!
real!
There are thousands of troops and horses, and there are swords and guns everywhere. What if someone who doesn't open his eyes gets hit by me, or if he falls or touches something while galloping, what should I do?
There are not even antibiotics these days, so if you are really injured, it will be a matter of fate.
After returning to his study with a gloomy face, Fang Fengzhu, seeing his expression, immediately came up to him and asked worriedly: "Your Majesty, what is your mission?"
"It doesn't really matter. He asked me to hunt with him in Shiping next month."
With a cold face, Li Yuanjia said angrily: "I don't know why your Majesty asked me to follow you... I have never hunted before!"
He has really never gone hunting. After all, he has been playing with pen and ink since he was a child, so he has no idea what to do when he goes there. Moreover, these days, people are very strict about their words, and there is no reason to refuse the emperor's order.
But after listening to his words, Fang Fengzhu blinked in surprise and said, "Your Majesty, what's so difficult about this? Just bring the guards over there and let them arrange it..."
