Many of the tasks done by craftsmen cannot be done by one person, and many people need to communicate with each other when they cooperate.

So, they have their own set of jargon cutouts to simplify communication, including gestures.

This kind of jargon incision is usually related to the dialect, it is very territorial, and the gestures are relatively general, but it also has this nature.

Fortunately, no matter how old or young the craftsmen in this vote are, they are all from Jiangnan Road, and Xu Wen's gesture Fang Jueming can easily understand it.

It was because he understood it that he was shocked.

Before, he only barely understood the meaning of the Pythagorean theorem and made the problem. He didn't know why the craftsmen were teaching them this.

But Xu asked these gestures, but he instantly understood, such a simple theorem can actually be seen everywhere when doing work, and it can often be used!

Whether it is architecture or furniture, the essence is a comprehensive application of various geometric figures.

They can't do without size, and they can't do without calculations.

Experienced craftsmen can calculate the length of the need based on experience and some commonly used formulas, in fact, the essence is the application of such a theorem.

For example, some angles cannot be measured with a ruler due to different positions or special sizes, so they can be calculated by applying such a theorem and formula. Even if there are places where measurements can be made, the calculation will be simpler and clearer.

The craftsmen and officials summed up the experience of the mature craftsmen in a very concise way and taught them.

This theorem is worth a thousand dollars in itself!

And Xu Wen quickly discovered the key to it, and showed it in the most realistic way for them, and they could see it at a glance.

Fang Jueming was serious about the nightly "game" before, but in fact, the main reason was that he was so strong that he refused to admit defeat, and wanted to win Jiang Wangfeng and them from all angles.

But now, Xu Wen only used a few gestures to make him understand the true value of these "games", and he became more serious in an instant.

For people like them, this is an extremely rare opportunity that may not be touched once in a lifetime!

For Xu Wen, this is actually not a big deal.

Mathematics is the foundation of all practical sciences, and architecture and industrial production are no exception.

Were there few mathematicians and scientists in ancient China?

Not less.

They combined scientific theory with practical work and wrote many monographs on the subject.

But again, in ancient times, the two divisions were very serious, and a small number of elites have always been at the forefront of mankind, but the broad masses of the people cannot even read and write, and they are simply unable to form such a cognition.

Xu Wen noticed that among the young craftsmen who went to the Western Desert this time, except for Jiang Wangfeng and himself, there were basically no outstanding results in this college examination, and most of them were very talented, but their backgrounds were really not very good.

Background limits their cultural level and vision, maybe they can become very capable and have a good future after training, but at this stage alone, they are indeed very limited.

People like them may not be difficult to get through, but as long as someone clicks and clicks the location, it is not difficult for them to understand.

They themselves have a lot of practical experience, and what they lack is only the habit of linking theory with practice.

Xu Wen clicked at this time, using the simplest and most understandable method.

In an instant, Sun Si and Chen Wannian suddenly realized, and the confusion on their faces was swept away.

"Sun Si. ”

"Here!"

"Hook is 21, strand is 15, and the geometry is ten, nine, eight, seven......"

Sun Si closed his eyes and meditated, and when he counted down to one, he opened his eyes:

“666。 ”

Sun Si replied. He wasn't too quick to calculate, but his tone was very firm, and he didn't have the slightest doubt about his answer.

"Correct. ”

Yan Jiangguan's expression was subtle, first glanced at Sun Si, and then glanced at Xu Wen lightly.

"Chen Wannian. ”

"Here!"

"The hook is 18, the strand is 12, and the real geometry is ten, nine......"

Also counting down to a moment, Chen Wannian also replied:

“468。 ”

"Correct. ”

The crowd fell silent for a while, followed by an irrepressible commotion.

Yesterday they couldn't do it at all, how can they do anything today?

What kind of elixir did they take?

"The game isn't over yet, so don't worry. Yan Jiangguan said lightly, and the audience barely fell silent.

The tenth round is also an application of the Pythagorean theorem.

The ninth round is tentative, the Pythagorean numbers are relatively small, and the tenth round is slightly larger, and the difficulty has increased accordingly.

In this round, one person was eliminated in Fang Jueming's group, and Chen Wannian was also eliminated because he was negligent and made a one-digit mistake.

In the end, Fang Jueming's group scored a total of fifty-nine, and Xu Wen's group was also fifty-nine like them, which was a tie.

Both sides tied for first place, each plus five points, until now, the total score of the group of the Fang group is still higher than that of the Xu group, but the single score, Fang Jueming is still behind Xu Wen.

The game ended here, Yan Craftsman said a few words and let them go to rest, as soon as the craftsmen left, the crowd roared, and a bunch of people crowded next to Sun Si and Chen Wannian.

Xu Wen slipped out first and talked to Xu San.

Xu Wen had taught them these things when they were in the old wood field before, and Xu San's performance in the past few days was not high-profile, but it was very stable.

Xu Wen had an idea and was discussing it with Xu San.

After a while, Jiang Wangfeng also came over, standing next to him and listening carefully.

Just halfway through speaking, Xu Wen suddenly felt that there was someone next to him, and when he turned his head, Fang Jueming was wandering not far away, his eyes were looking at them, as if he wanted to come over and say something, but he was a little hesitant.

Jiang Wangfeng's expression immediately became a little unpleasant, and he didn't know why, the two of them were not on the same page from the beginning, and they didn't like each other.

Xu Wen patted Jiang Wangfeng's shoulder, looked at Fang Jueming, and asked, "Is there anything wrong?"

Fang Jueming hesitated for a moment, then walked over and faced the three of them.

There was silence again, and Jiang Wangfeng couldn't help but say, "It's late, I have to hurry tomorrow." ”

“...... I'm losing!" Fang Jueming suddenly raised his head, looked at Xu Wen, and said very seriously.

Jiang Wangfeng shut up instantly, and looked at Fang Jueming in surprise, as if he had seen this person for the first time.

"In terms of group results, you are still above us. The single score is only one point short, and now it is just on the road, and it will take a month to get to the West Desert. Xu Wen said calmly.

"The score doesn't matter, I did lose. Fang Jueming had already opened his mouth, and then he said very smoothly, "It's not for you to remind me, I can't think of any use for Pythagorean Xuanshi at all." The realm is different, I lost from the beginning. ”

He spoke quickly, his expression was a little unwilling, and a little comfortable. After finishing speaking, he turned around and left, not giving Xu Wen a chance to ask them questions at all, and in the blink of an eye, his figure disappeared into the crowd.

Xu Wen and the three watched him leave, and Jiang Wangfeng suddenly said, "Damn, I lost." ”

He gritted his teeth, a little hateful, and didn't explain how he lost and where he lost.

Xu Wen suddenly smiled and patted Jiang Wangfeng's shoulder again.

"Little brother Yan. A voice suddenly came from behind the three of them, calling Xu Wen's pseudonym, very polite.

Xu Wen turned around and saw Craftsman Yan smiling slightly, holding a small wooden box in his hand, the box seemed to look a little familiar?
