This night, destined to sleepless, almost every household in Liujiazhuang is doing the same thing.

The conditions of Fatty's family are not bad, at least much better than ordinary people, this night, as soon as he got home, Fatty was dragged to the living room by his father.

"Didn't you say today that your husband should teach skills? How's it going? Have you ever been lazy? ”

The chubby father is a merchant who travels from south to north, is well-informed, and is even more interested in education, this time it is difficult to find a teacher, so he naturally has to strictly supervise.

"Dad, don't worry! Mr. taught me a lot of things today, and he said that I was smart. Chubby smiled and took out a blank piece of paper from his arms.

"Hey, this thing is called paper, and the gentleman said, this thing is precious, and there is no other place to sell it! He wrote everything he taught today, as long as I can understand the things on it, it will not be a problem to be a bookkeeper! The little fat man waved the white paper, very proud.

"You kid!" Daddy Li slapped Xiao Fat and fanned him, "Smack!" "It made Chubby dizzy.

"Let you be scared, it's only been a day of school, and I'm going to get up in front of Lao Tzu, I can't teach you a good lesson!" Daddy Li snorted angrily and taught Chubby a lesson.

"Bring it!" I grabbed the paper and looked at it slowly.

Zhou Chen's multiplication formulas and explanations are quite detailed, symbols, usage, and interpretations, each point is expressed in detail, and there are even graphs as analysis. (Zhou Chen: Nonsense!) The system is so expensive, how can it be possible to sell inferior products! ）

"Awesome!"

Although Daddy Li has not gone to school, he has learned a lot of things over the years, and he is even more proficient in arithmetic.

It is easier for people with a foundation to understand the multiplication formula, and this is the case with Daddy Li, according to the method on the paper, Daddy Li was surprised to find that the things that he had to calculate for half a day were easily solved!

"Little fatty, this time you have met a treasure, this gentleman is really knowledgeable, and this arithmetic alone is far beyond ordinary people."

Don't wait, the little fat man sighed, and Daddy Li said again: "I've heard these formulas said outside, and there are one or two sentences in your father's book collection, but there are really no detailed inductions, sorting, and explanations like your husband, if you learn this thing, don't say anything else, it's no problem to be an account room!" ”

"That's what our husband said, he said that as long as we study hard, we can become a bookkeeper in three months!" Although the little fat man was beaten, the smile on his face remained undiminished, his head was held high, and his intention was undoubtedly revealed, as if Daddy Li was praising himself.

"You boy! Go do your homework! When the time comes, I'll learn the skills, and I'm counting on you to teach me, daddy! Doing business, dealing with numbers all year round, very troublesome, your husband has the ability, think there will be his own way, learn hard! ”

Saying that, Daddy Li locked Xiaopang in the bedroom, for fear that he would not waste time seriously

The same scene is constantly playing out in a family in Liujiazhuang, but Zhou Chen's detailed version of the multiplication formula for these children has been passed on by some knowledgeable parents.

The creator of the multiplication formula is not Zhou Chen. As early as the Spring and Autumn Period and the Warring States Period, it was recorded that sentences such as "3927", "6848", "4832", "6636" and other sentences can be found in books such as "Xunzi", "Guanzi", "Huainanzi", and "Warring States Policy".

However, there is nothing like Zhou Chen who specializes in induction, updating, and teaching. At this time, most of the private schools taught the Four Books and Five Classics, poetry and Confucianism, and very few gentlemen would talk about arithmetic, and some gentlemen were afraid that they had never even been exposed to arithmetic.

Most of the account rooms are taught by hand, or by virtue of experience, oral learning, so there was such special information as Zhou Chen?

Yes, this multiplication formula has been passed on by people with a heart.

As soon as the mantra appeared, detailed annotations and markings gave some bookkeepers who could only add and subtract to gain insight. Even those experienced old tent rooms have also benefited a lot, and with this formula, the calculation speed is obviously much faster.

I don't know when it began, this multiplication formula has become the treasure of the account office near Liujiazhuang! And Zhou Chen's name also spread with this mantra. Now everyone knows that there is a Mr. Liu in Liujiazhuang who is teaching, and he is a scholar and a scholar!

Zhou Chen didn't know these things. However, in the next few days, he found that there were a few more children in his classroom, who had appeared out of nowhere, and listened very carefully with small wooden boards.

As the so-called education is classless, Zhou Chen still agrees with Confucius's point of view, in his previous life, he received unfair treatment, and he was treated as a model by the teacher in class, and he hated this kind of thing.

It doesn't matter where these children come from, they don't care about them all! As long as it is the original student's things, they are all evenly printed, and the exercise materials are also all available.

These later children were surprised to see Zhou Chen take care of himself so much, and he worked very hard to learn, and the learning speed was even Zhou Chen, who was a teacher, was also surprised

The days passed like this, Zhou Chen's name became bigger and bigger day by day, and in a few months, his reputation had even spread to the next county.

The name is big, and the troubles naturally become more, and the people who come here one after another, the children of the family, the literati, all came to the vicinity of Liujiazhuang. As soon as Zhou Chen started speaking, the classroom was surrounded by iron buckets, and countless heads were densely packed on the windows, writing and drawing on the bamboo slips he brought.

Zhou Chen's first taught pinyin, addition, subtraction, multiplication and division, and then taught everyone to rank vertically, which greatly accelerated the speed of operation. And Xiaoya they have mastered what Zhou Chen taught after a few months of study, and some older children have even gone to the town to become a settler, because of their fast speed and high precision, they are deeply loved by the major bosses, and they have become sought-after goods one by one.

There are also some younger ones, and their families don't need their contributions, and they still listen to lectures in Zhou Chen's class and learn new knowledge.

is different from before, but now Zhou Chen is busy, teaching the students who wake up in the morning, teaching them physics, more esoteric mathematics, arithmetic, and even adding some stories about the art of war in the afternoon; Prepare materials and topics in the evening. These seals alone have already accounted for most of the personal packages in Zhou Chen's system, and the card points have not been spent.

After a few months of hurried time, Zhou Chen had become accustomed to this peaceful day, and sometimes even had the idea of staying. But he also knew that he had to go! The troubled times are coming, under the nest, how can there be eggs? Only by making yourself more powerful can you survive the troubled times!

"It's time to go! While you still have some time, you need to do some preparation in advance, and if you can, find another talent or two. Zhou Chen secretly made a decision in his heart, preparing to leave together as soon as Dian Wei arrived.
