"I want to teach them how to count Hu people first. ”

Xu Wen found Yan Craftsman and said straight to the point.

On this day, he asked Jiang Wangfeng about the account book of the Hu people, and forcibly asked him to recall two "symbols" and write them down.

The drawing was distorted, but it was still clear that it was indeed Arabic numerals.

Xu Wen breathed a sigh of relief and made a decision.

"What kind of Hu people?" asked Yan Craftsman curiously, without directly refusing.

In fact, they are just fixed symbols, and it will be relatively simple to express. It was my master who taught me before. "If you don't decide everything, Master, Xu Wen has learned it now.

He listed simple symbols such as Arabic numerals, addition, subtraction, multiplication and division to Yan Jiangguan, and also listed an auxiliary calculation formula for addition by the way, and showed it to Yan Jiangguan on the spot.

Foreigners and Chinese are both human beings, and many ideas are actually the same, which is just a way to express themselves.

Moreover, there were originally all kinds of conventional symbols within the craftsmen, and Yan Gongguan had seen a lot of them, so it was not surprising to him that Xu Wen had added a new set.

"That's good!" he said, touching his chin, and immediately saw the subtlety in it, and his eyes sparkled.

"I'll think about it......" He pondered for a while, then picked up his pen and drew a scoop of gourd with two new equations next to him, one for addition and one for subtraction.

Xu Wen was a little surprised. If nothing else, this ability to draw inferences is enough......

"What about multiplication and division, there should be one, right?" asked Yan Jiangguan.

"Yes. Xu Wen also listed it for him to see.

"Wonderful!" saw him finish the list, and slapped the table loudly.

He saw the beauty almost instantly, the kind of logical thinking, too simple and clear, directly presented the process and the result clearly in front of him.

"Yes. He didn't hesitate to say that he would add these to the course content.

So, that night, Xu Wen got up and went out of the line and stood at the forefront of all the craftsmen.

"Tonight, at the request of Master Yan, I will teach you a set of counting methods. He first lifted Yan Jiangguan out to strengthen the credibility of his words.

The craftsmen below looked puzzled and looked to the side in unison.

Yan Jiangguan moved a chair and sat next to him with a smile on his face. Hearing Xu Wen's words, he nodded in approval.

In his opinion, at this time, Xu Wen did not forget to bring up the craftsman official, and he was still quite good at being a man.

Fang Jueming opened his mouth wide, his face shocked.

Yesterday, he felt that Yan Fourteen's level was higher than his own, and he admitted defeat to Xu Wen, and today the other party stood on the podium, and even his identity changed.

What's going on?

Is the gap between him and Xu Wen actually so big?

At this time, in fact, even Xu asked himself a little strange.

Being in ancient times, standing here, teaching a large group of ancient Arabic numerals and mathematical symbols, there is a very unrealistic feeling.

"This counting method was learned from the Hu people, and it is very simple. The first is the ...... of ten numbers"

Next, he wrote on the wooden board prepared by the Yan craftsman, and below he three hundred craftsmen of different ages took branches and traced them on the dirt floor in front of him.

For modern people, these ten numbers are too simple, and it feels like they will be able to master it from birth, and children will be able to master it before they can read and write.

But that's because modern people live in such an environment, these numbers are everywhere around us, and you can see and hear them everywhere.

Without such an environment, it is not so easy to memorize ten symbols that have never been seen before, and accurately correspond them to the numbers one by one.

Fortunately, these craftsmen are all specially selected by the imperial court, and their intelligence is absolutely fine, and their qualifications are not dull. In less than half an hour, almost everyone remembered it, Xu Wen took the test once, and there was no one who remembered it wrong.

Yan Jiangguan was also very satisfied, and with a wave of his hand, he added a point to everyone.

Xu Wen can even get work points in class!

Everyone's spirits were lifted, and Fang Jueming gave Xu Wen an extra look.

The numbers are followed by mathematical symbols, which do not need to be memorized, but can be learned in practice.

Xu Wen didn't teach mental arithmetic right away, but taught the way of using these symbols to list the equations.

A few days ago, the craftsmen had learned to add, subtract and multiply, and now they learned to calculate the results by using vertical drafts, and they unexpectedly felt very simple.

So, Xu Wen also taught division by homeopathy.

At the end of the teaching, he also gave the "classmates" ten questions to test their learning results today.

The first six are all more complex addition, subtraction, multiplication and division formulas, as long as the result, there is no time limit.

The last four questions are application questions, combined with the actual work of the craftsmen, and various numbers are put into the calculation, and the answers are required.

Many people instantly understand why they want to learn these things, and their passion increases.

This exam is the most conventional kind, with a limited time, half an hour, answering questions separately, and not allowing each other to communicate with each other. When the time comes, the examiner marks the papers on the spot and reports the scores.

Before the exam, Yan Jiangguan directly reported the rules, and this exam was included in the evaluation of work points.

Scoring is still conducted in the form of squads, and all teams with a total score of 48 or more will be given 2 points, and 36 points or more will be given 1 point. Those who violate the rules will be disqualified from the exam, and each team will be deducted two points.

In addition, Xu Wen, as the host of the exam, directly counts the full score and adds two work points.

When the rules were announced, there was silence below.

There are still a lot of clever people, and when Xu Wen was lecturing on the stage and giving questions, some people were wondering what to do with the exam later, and whether his score counted.

Now Yan Jiangguan directly explained, count, of course count!

Yan Gongguan looked down and found that not only did no one question it, but several people became excited and a little eager to try.

He was stunned at first, but immediately figured it out.

They actually didn't understand Xu Wen's real ability, in their opinion, Yan 14 just had a skill, served the court, and was used by the court. These two points of work are the reward for him.

Yan 14 has such an opportunity, and of course they can have it.

Standing on the stage today is Yan 14, and tomorrow may be them.

This is actually a very logical idea, it is that he learned about Xu Wen's origin in advance, so he knows how unusual this young man is.

It doesn't matter, they'll find out soon.

Moreover, for the misunderstanding of these people, Yan Jiangguan is still quite happy to see it.

Then the next day, Xu Wen stood on the stage again.

"What I'm going to teach you today is abacus mental arithmetic, which is a method of quick mental arithmetic addition, subtraction, multiplication, and division. ”

Are you again?

How do you know so much?

Is mental arithmetic the secret of Sun Si and Chen Wannian's rapid progress?

He's going to teach everyone?
