(The Year of the Ox is here, I wish you all good luck in the Year of the Ox, a happy family, good health, and a successful career.) ）

Dragon Twelve finally ate the braised pork, but only after night had completely fallen.

According to the children's habits, it is time to go to bed at night, because there is neither oil lamp nor electricity at this time, and many people are malnourished and lack vitamins, and when it gets dark, they cannot see anything. But it didn't work out in this place, Zhao and Ju were very willing to invest in the education of children, and four torches made of grease were lit, and the main house of the fourth entrance was bright.

The children all looked at Zhao Youju with great curiosity, as well as the outfit behind him.

It was a huge wooden board, the black paint was shiny, and Zhao Youju was holding a white thing in his hand, looking a little dazed.

He seems to have returned nearly a thousand years later, in a ravine in the west where he once taught, using homemade rudimentary tools to spread the fire of modern civilization.

The blackboard is simple, but the making of chalk is not an easy task, and it needs to be mixed with plaster and clay in proportion. Zhao Youju only knew the formula, so it took a lot of time to trial and make, and the final product was also the irregular thing in his hand.

But that's enough.

"From tonight onwards, you will study here for an hour and a half every night." Zhao Heju fixed his mind: "There will be an exam every month, and those who fail the exam will be starved for a day and flogged ten times." ”

The children were astonished when they heard this, for they had never heard of the Lord's house letting them read on the first day they bought the maids.

At this time, the status of domestic slaves was very low, and not only were they not allowed to participate in the imperial examinations, but their children and grandchildren had to change their careers and cut their nationality for three generations before they could participate in the imperial examinations (Note 1), so studying was of little significance to these children who had been sold into slavery.

"What I'm going to teach you today is numbers." Zhao and Ju didn't give the children much time to be stunned, and after a pause, he raised the chalk.

Although his homemade chalk was far less polished than that of later generations, his chalk writing was still beautiful, and he practiced a lot these days, so that this little body could grasp chalk as flexibly as later generations. He first wrote the 10 Chinese characters from zero to 9 on the top row of the blackboard, and then marked the corresponding Arabic numerals under each Chinese character. Invented by the Indians, this symbol is very simple and suitable for children with low IQs, just right for the beginning of mathematics.

"Whether it's settling accounts or measuring acres, these numbers are indispensable." Zhao and Ju are accustomed to writing from left to right when writing, if they are full of poetry and books, they will definitely not be used to it, but these children are almost illiterate, so naturally there is no problem.

The choice of mathematics as the first part of the basic education for these children was deliberate. First of all, because Zhao and Ju believe that mathematics is the beginning of all disciplines, and philosophy is the end of all disciplines, especially in natural sciences, if there is no mathematical foundation, it will be difficult to move forward; Secondly, no matter how secret he may be, there will always be omissions in this age by his own strength, and educating the servants to count will not arouse the suspicion of the scholars and doctors who are in charge of public opinion, after all, as he said, mathematics can be used to settle accounts and measure acres; The third reason is that these children are at the age when they begin to learn basic mathematics, and if they reach the age of Xiaocui or Zhao Yong, their ability to accept new things has weakened, and it is difficult to learn well.

The ancient Chinese did not attach great importance to mathematics, otherwise mathematics would not have become one of the six arts of Confucianism (Note 2). Even in the imperial examinations after the Sui and Tang dynasties, mathematics was also a part of the examination, and in the Tang Dynasty, there was a subject of clear arithmetic in the regular examination (Note 3). In fact, it was still a precedent for Meng Yuan to take scholars based on the content of the four books, and Zhu Ming just followed the conventions of Meng Yuan, and in the previous imperial examinations, the content was far richer than the rigid and imprisoned four books.

Therefore, teaching these servants to do math, there is no need to worry about the scholars' discussions, and there is no need to worry about the suspicion of the villagers, even if one or two people with a heart know about this, they will only praise the Zhao family for their generosity.

Dragon Twelve looked at the twenty symbols on the blackboard, and his eyes straightened.

He's not a very smart person, that's why he fell to the end in the house rules, and these twisting characters really make his head as big as a fight.

Li Ye is the same, stronger than Long Twelve, he at least knows how to pull his fingers to compare one, two, three, four, and he also knows that when one hand is not enough, switch to the other.

After Zhao and Ju taught the ten numbers three times, they stopped, and a few maids gave each child a small blackboard made of wood, a piece of chalk, and a rag, the children were a little dazed at first, but this time it was Li Ye who was the first to react, he grabbed the chalk with great interest, and wrote a horizontal on his small blackboard crookedly: "One." ”

The rest of the children did the same, and Chen Zicheng carefully studied the handwriting left by Zhao and Ju on the big blackboard before writing, so it was written fairly and fairly, and it seemed to be more standard than Zhao and Ju's own writing. Chen Ren also wrote Chinese characters smoothly, but when he wrote those twisting numbers, he was a little struggling, he secretly glanced at Chen Zicheng's writing, and found that the other party wrote very well, and his heart was even more anxious.

Under the instigation of Zhao and Ju intentionally or unintentionally, a sense of competition has already arisen among the first batch of children, Chen Zicheng and Chen Ren, Long Twelve and Li Ye, they don't know how their fate and each other's fate will intersect at the moment, but they vaguely feel that the other party is not pleasing to the eye.

An hour and a half is equivalent to three hours, and these children have been yawning for a long time, but they are afraid of their new masters, and no one dares to show their difficulties. Zhao Youju was very satisfied with it, this should be the advantage of returning to ancient times. At the time when he crossed over, the education industry had been stirred up by the copper-smelling and brain-dead juvenile law, and teachers without teacher ethics and talents formed a perfect match with students who lacked the discipline of learning interest and discipline, tormenting and tossing each other. He is the master of these children, if these children do not want to make progress and have no intention of learning, they will naturally have family rules and family laws to deal with, whipping, hunger strike, confinement, and use whatever they want, and there is no need to worry about any opposition at all.

Zhao Youju once watched a video on the Internet, in which the stud man who insulted the teacher and the elderly teacher who swallowed his anger deeply pierced his heart. This is not only the problem of the stud man personally, but also the elderly teacher, and the society that laughs at the poor and not at the greedy.

If you don't teach, your father's fault, your teaching is not strict, and your teacher is lazy.
