"One is 1, two is 2, and three is 3......"

In class, Li Tai took a small wooden stick and tapped the content on the board book: "The front is orthography, the back is the number of stools, the number of stools is used for calculation, and the paper must be orthography!" ”

There were more than 20 people sitting in the classroom, young and old, some of whom had received enlightenment and had excellent grades, and some of whom were old men who were coarsely literate. There are also the stewards who have emerged in the past few months in the trilogy, and they are all seriously accepting the arithmetic enlightenment of Lord Lang to them.

The knowledge of the ancients is really outrageously low.

Li Tai brought more than a dozen family members from Dongzhou, because they grew up with him since childhood, and most of them have also received a preliminary education. Several people who are smart by nature, such as Li Quji, etc., have their own academic literacy is even a few points higher than that of Li Tai, the lord of the Lang.

However, in the newly acquired Shiwu tribe in Kansai, there are very few literate people. Li Tai didn't expect all of them to be able to read poetry and books, but as the family affairs became more complicated, these stewards should know at least the math and bookkeeping.

Especially after Zhou Changming was appointed as the commander of the capital, Li Tai seconded Li Quji and several other family members who were both civil and military to help him rectify the township regiment.

The mathematical development of the ancients was not low, not to mention Zu Chongzhi, who had calculated pi in the Southern Dynasty, and the textbook of "Sutra of Calculation" circulated in the Northern Dynasty was actually not bad.

There are many practical questions in the "Sutra of Calculations", and the types of questions are closely related to life.

Now there is money for him, and he will pay for it with interest. At the beginning of the transfer, you will get twice the profits, and you will pay back one hundred. The second transfer of profits is tripled, and the money is repaid two hundred. The third transfer of profits is four times, and the money is repaid three hundred. The fourth transfer of profits is five times, and the money is repaid four hundred. Finished, all the multiples of the transfer of interest are through the capital, now in addition to the original capital, there is 5,950 money, ask the original geometry?

Today with someone money, the first person and three money, the next person and four money, the next person and five money, with the next time, transfer one more money, and the end, but also gather equally, people get a hundred money. Ask people geometry?

Li Tai can understand these questions, but if he doesn't calculate them carefully, it will be difficult to blurt out the answers. It is obviously inappropriate to use this as a teaching material to teach the illiterate characters.

He didn't want high-end mathematicians to calculate pi, but at least the basic arithmetic problems of material increase and loss at home had to be done, so he taught them simple and easy-to-calculate Arabic numerals to quickly master basic mathematical operations.

Of course, when you really make accounts on paper, you still have to use regular traditional numbers.

After finishing a math initiation class, Li Tai assigned a few more math problems as homework, and then moved to another class door. Seeing this, Li Zhusheng, who was enlightening the children in the hall to eliminate illiteracy, let the students study on their own and walked out of the classroom by themselves.

"Is the checkered engraving of the account book ready?"

The time-traveler returned to the era before the Tang Dynasty, did not engage in printing, first had no brain, and second had no conscience.

Li Tai didn't get started to engage in the printing of scriptures and righteousness, and he had made several versions of the official documents and account forms, and ordered the subordinates to have carvers who were good at carving them, and the matter had been ordered to go down for more than half a month, so I thought about it today and asked.

After Li Zhusheng heard this, he returned to his residence next to the school, and soon took out a three-sided 16-carat wooden engraving plate and handed it to Li Tai: "The stereotype has been done, but the ink is still being blended." ”

Li Tai took the engraving, pressed his palm on the embossed pattern, turned over his hand and saw that the indentation in the palm of his hand was still clear, and nodded with satisfaction: "After the ink is properly prepared, the printed material will be brought to me for the first time!" ”

With these printed fixed forms, the names of some commonly used materials are printed with engraved seals, and then the manor stewards only need to fill in the specific entry and exit figures, and the efficiency of making accounts is naturally greatly increased, and it is more convenient for Li Tai to check the accounts.

"It's a pity that the black otter is too crazy to give me face. If I am made an official, the administrative efficiency of the government can be improved for him, and the cost will be lowered. He deserves to be an emperor when he gets old! ”

Feeling that he was shrewd, Li Tai couldn't help but sigh.

Zhou Changming was promoted from a mere township commander to the governor of the handsome capital in one fell swoop, and although Li Tai was really happy for him, he also suffered a lot of shock.

Hate people, hate me, human nature, he is a traverser for more than 30 chapters, and he is just an idle little business in Gao Zhongmi's Situ Mansion, which shows that Yuwentai knows people stupidly!

"Ah Lang, someone outside the village sent a post to visit, calling himself Shi Jing, I think it should be a member of the Shi family."

Li Yan, who was in charge of the front hall, walked widely, shook the two famous cards in his hand from a distance and said.

Li Tai couldn't help but be surprised when he heard this: "Isn't Shi Jing locked up in a pigsty?" Why did Shi Jing pop up again? ”

"It's not respectful, it's quiet!"

Li Yantou was also happy when he heard this, and handed the name card to Li Tai before entering, and Li Tai took a look at it, and then he understood.

This Shi Jing's name is pasted from Chen Jingzhao Dulingren's clan, and there is also a Weilie general. Thinking about it, it should be Hongo Shi Gong who felt that he couldn't suppress Li Tai, so he invited Jingzhao's family to be a lobbyist.

In the later period of the Northern Wei Dynasty, miscellaneous generals were already overflowing, and in the Western Wei Dynasty, this flood was even more serious. For example, when Zhou Changming was still serving as the commander, he had the rank of seven-rank general, and after serving as the governor of Shuaidu, he was added to the rank of six-rank Xuanwei general.

As for how many grades this General Weilie is, Li Tai really doesn't know. Once the name is overflowing, it will no longer be solemn, in short, in his opinion, as long as it is not the general of the Zhu Kingdom, everything else is almost meaningless.

Aside from this Jing Zhaoshi family's name post, another post caught his attention. The owner of the famous post is named Lu Rou, a person from Fan Yang, a scholar from the province of Renguan, and there is actually a knighthood of Rongcheng County.

On the basis of the succession of the Western Wei bureaucracy to the Northern Wei Dynasty, there was indiscriminate development, and Li Tai did not know how heavy the authority of the scholars was, but the prestige of the Fan Yang Lu clan couldn't help but make him think more. The reason why He Batsheng treated him well was because he was born in Lu Shuhu, the uncle of the Fan Yang Lu clan.

"Do you have a relative named Lu Rou at home?"

Li Tai thought for a while, but he couldn't remember if he had this relative, so he asked Li Yantou.

Li Yan scratched his head and said with a dry smile: "Ah Lang still doesn't know, how can the servant know?" ”

"Forget it, you go and summon Uncle Nagisa to the middle hall."

No matter what kind of relatives it is, this Lu Rou came with the Shi family, presumably as a lobbyist. Li Taizheng is planning to slaughter the Shi family, and no one can give face.

When Li Tai walked to the middle hall, he instructed his family to bring in visitors. Not long after, a sturdy young man in his early twenties and a middle-aged man strode up.

"Jing Zhao Shi Jing, I have seen Li Lang. Li Lang ......"

When the young man walked closer, he raised his arm and waved his hand, and before he finished his polite words, the middle-aged man had already stepped forward, his eyes were looking directly at Li Tai, and the corners of his mouth trembled slightly and said, "You, you are, you are Apan?" When, back then, when I traveled south, I was, once went to the countryside to visit, Apan, you, you were just, just a naughty boy frolicking in front of the court, but I didn't want to be ...... now."

Li Tai was so excited that he couldn't say anything when he saw this middle-aged man, and he was surprised for a while, he thought that even if he had relatives, he was just a face-saving relative who didn't come and go often, but he didn't expect this Lu Rou to see him, and he was so excited that he couldn't help himself.

He was feeling a little embarrassed, Li Zhusheng had already walked widely, pointed at Lu Rou from a distance and shouted, "Is it really Zigang, Lu Dalang?" ”

"Nagisa, Nagisa, it's me, it's me!"

When Lu Rou saw Li Zhusheng, her expression became even more excited, and she strode forward, hugged Li Zhusheng's arm and slapped it several times: "No, I didn't expect that we could still meet each other, but it was in this Guanxi." Are you coming with Apansi? Is he well, yes? My aunt and aunt are still in Qinghe? ”

The two middle-aged men stood together with their arms crossed, each talking goodbye with enthusiasm on their faces. As for Li Tai and the young man of the Jingzhao Shi family, they were left to the side, just looking at the two of them.

"Ah Lang, Lu Da is the son and nephew of the master's mother's foreign family......"

Li Zhusheng also guessed that Li Tai probably didn't know Lu Rou, and only remembered to introduce each other after a while, it turned out that Li Tai's mother Lu was Lu Rou's cousin, Lu Shuhu's blood sister, and the relationship between them was not far away.

"It's rude to see each other when we were young, have vague memories, and snub our cousins!"

Li Tai saw that Li Zhusheng and Lu Rou had something to talk about, but it was inconvenient to be estranged anymore, so he stepped forward to salute again.

"Ah, Ah Pan, what a handsome and good son! Like your mother, not like you. When my aunt got married, I sighed when I was in the house, where can I use rich makeup, my aunt has already brought the beauty of one door and one door to your house! ”

This Lu Rou was not only excited, but also a little stuttering, pulled Li Tai up and down to sigh with emotion, and then pointed to Shi Jing, who was becoming more and more embarrassed next to him, and said: "Fortunately, this Shi Langjun, I visited Cui Yuanjun yesterday to ask for advice, and I happened to be on my cousin's mansion, so I knew that Ah Pan, you also came to Kansai!" So that Jun and his ministry are busy, and I am idle, so I will go to the countryside to see you with Shi Langjun! ”

When Li Tai heard this, he was also a little curious, could it be that their family still had relatives who were big officials in the Western Wei Dynasty?

"Thank you Shi Langjun, if it weren't for this, my cousin and I don't know when we will see each other."

Although the mind of the Shi family has not changed, but the politeness on the face should be taken into account, Li Tai smiled and nodded to the young man Shi Jing and said.

Shi Jing hurriedly clenched his fists and said, "Li Lang's words are serious!" Lang Jun has not been in the township for a long time, and his voice has gradually spread, even if there is no news from me, everyone will know it soon. On the contrary, I asked to see me this time, full of shame, and begged Lang Jun to forgive the offense of the villagers! ”

"Yes, Pan, what's going on? I heard that you have not been in the country for a long time, and you have had a lot of quarrels with your fellow villagers, and there are more rumors that you rely on the majesty of Master Heba and do not want to get along with the villagers in peace......"

When Lu Rou heard this, she also frowned, turned her head to look at Li Zhusheng and said, "Ah Pan, he is still young, but you shouldn't be Zhusheng!" Let's move westward and live in Guanzhong, but we must not lose the spirit of tutoring and bully the corporal! ”

"It turns out that this Shi Langjun told his cousin like this, so I have to talk about it carefully! I'm not afraid of the treacherous reversal of right and wrong in the township, but I don't want to be close to the old and misunderstand that I have lost my family education! ”

When Li Tai heard this, his face suddenly sank, and his eyes looking at Shi Jing became fierce.
