"Promoting Arab ...... Tianzhu numbers, let's start with Han Wangfu. ”

Standing in his study, Li Yuanjia suddenly smiled, crumpled the white paper with the name written on the table, and then threw it into the trash can next to him.

Who will be the housekeeper of this Han Wangfu, in fact, Li Yuanjia really doesn't care.

Perhaps compared with the old but old-fashioned Han Shan, the younger and more studious Han Lucheng will be more in line with Sun Peng's wishes, but on the other hand, compared with the old Han Shan, Han Lucheng also has an undeniable disadvantage.

For example, next year's wedding, for example, the interaction with the magnates of various families in Chang'an, Han Lu's achievements are far less experienced than Han Shanlai's. You must know that Han Shan was specially selected by the imperial concubine for Li Yuanjia back then, at least he has seen a lot of the world, and he will not be so easy to rush when he encounters things.

Li Yuanjia is doing things in the palace, not to let Han Shan step down.

His purpose is not even to use precise Tianzhu numbers to prevent corruption among the stewards, after all, even in the twenty-first century, the era when all financial systems are extremely perfect cannot be avoided, let alone this era?

Li Yuanjia's real purpose is just that.

Getting more people to use Arabic numerals is what Li Yuanjia wants to do. It's just that as the prince of the Tang Dynasty, Li Yuanjia has no power except for the fictitious position of Yongzhou Mu, and the one who can call the shots is in the Han Wangfu......

No, in fact, even Han Wangfu, Li Yuanjia is actually not completely in charge.

Because in fact, the Han Wangfu can be divided into "Inner Mansion" and "Outer Mansion", the Inner Mansion is Li Yuanjia's home, and the Outer Mansion includes the officials, guards, etc. allocated by the Tang Dynasty to each prince, which can almost be regarded as the kind of small country. It's just that after returning to Chang'an, King Han's "outer mansion" has almost existed in name only.

The first thing Li Yuanjia wanted to popularize was the "inner house" of the Han Wangfu.

This is a place where he has absolute authority, and only in this kind of place can Li Yuanjia say everything and do what he wants to do at will, and no one dares to oppose his decision......

……

The next morning, Li Yuanjia called Ma Liang over again.

"In the future, all the new stewards in the house must be able to use Tianzhu numbers!"

After taking a sip, King Han of the Tang Dynasty ordered seriously: "So you can ignore those who are over thirty, but as long as they are under thirty...... Give them a class, you have to come to class! ”

"Yes, King!"

Regarding Li Yuanjia's order, Ma Liang naturally nodded without hesitation.

However, although there was no hesitation on his face, Ma Liang was still a little unsteady in his heart. After all, he is only seventeen or eighteen years old, and which of the twenty-year-old stewards in the house will really convince him?

"Ma Liang, show me strictly!"

Obviously seeing Ma Liang's worries, Li Yuanjia's eyes narrowed, and he said coldly: "If there is anyone who doesn't listen, you can tell Han Shan directly and let him deal with it for me!" If Han Shan's handling can't satisfy you, just let me know! ”

"Goo-dong!"

Swallowing his saliva with difficulty, Ma Liang's voice trembled a little: "Yes, king!" ”

Although the king didn't say anything in his words, just listening to the tone and looking at the expression, Ma Liang had almost guessed what was not said later: if anyone dared to disobey the king's order and didn't study this Tianzhu number well, I'm afraid there would really be no good fruit to eat!

He still understands some of the king's temper.

Although he is usually mild-tempered and treats people well, he is the least likely to disobey his orders, as the events of the past two years have proven.

"By the way, there are two more books here!"

When Ma Liang was pondering here, Li Yuanjia handed him two books: "Basically, it's all the things you have learned, but this time I have rearranged it, not only to write in more detail, simple, and easy to understand, but also to add a lot of practice questions...... Take a good look at them yourself, and then use them when you come back to teaching. ”

"Yes, King!"

After hearing these words, Ma Liang's eyes suddenly lit up!

He was worried about how to teach those people to learn Tianzhu numbers, so the king took out these two books, which really solved the urgent need. Now it's okay, just go back and let those people copy all the books......

"Alas, what a waste!"

Watching Ma Liang respectfully take the two books, Li Yuanjia sighed secretly.

The two books, in fact, are Arabic numerals and four arithmetic, which are equivalent to the level of the first and second grades of primary school. Even the level of mathematics in the Zhenguan period must have far surpassed theirs. It's just that because of the existence of Arabic numerals, these two books have become priceless in this era!

How good would it be if such a thing could be promoted throughout Datang?

It's a pity that Li Yuanjia knew that this was just his wishful thinking, after all, when the emperor knew about it, he just gave him two words: nonsense!

So after thinking about it, all Li Yuanjia can think of is the interior of his palace.

It's just that when he thought that this simple and convenient counting method could only be used in his own big yard, Li Yuanjia felt very distressed in his heart - if this thing can spread out, not to mention anything else, the mathematical level of the ancestors should be able to skyrocket a lot, right?

"No way, take your time."

Looking at Ma Liang's figure slowly withdrawing, Li Yuanjia sighed again and began to think about it in his heart.

When the emperor returned from Luoyang, he would definitely offer these two books. Regardless of whether the emperor's attitude is good or bad at that time, and whether he can accept this kind of novelty, one thing Li Yuanjia can be sure of is that the second brother should not suspect himself because of his rash attempt at "academics".

After all, mathematics is also one of the six arts of a gentleman.

Now Li Shimin's throne is becoming more and more stable, and the constraints on the princes are getting smaller and smaller, and not long ago he even wanted the princes to be hereditary assassins, which gave Li Yuanjia more confidence.

Other than that......

"Uncle and father-in-law, in fact, you can also promote it."

After pondering for a while, Li Yuanjia decided to wait for the emperor and them to return to Chang'an, and immediately send one set of the two books to Yu Wenshi and Fang Xuanling. They don't need to talk about it for a short time, but even if it just arouses curiosity, it's good to watch it once!

After secretly planning for himself, Li Yuanjia took a deep breath and asked Han Shan to come over.

Then he took out two identical books, as well as a thick envelope, and handed them to Han Shan: "Send someone to send these things to Luzhou immediately and hand them over to the ...... of King Yu."

It's a little better today, but it's barely able to code words. It's still dizzy.,I feel like it's badly written.,Let's take a look at it.。
