"The most important thing in the way of mathematics is to calculate ......"

"Today, I and you, what I want to talk about is this arithmetic ......"

Zhang Yue sat in the shade of a tree and talked eloquently.

There were more than 200 scholars around, listening attentively and not daring to miss half a sentence.

Even Yuan Chang obediently stood on his side, and his entourage diners worked hard to write and quickly record.

"The ancient ancestors, knotting the rope ...... remember," Zhang Yue said softly: "The rope head has become the first counting tool......"

"And to the three generations, there are the first kings to count the chips, the law to vertical and horizontal system, every hundred and enter, the trick said: one vertical and ten horizontal, one hundred and thousands of stiff, thousands of each other, ten hundred is quite ......"

"This method has been passed down to this day, and it is a good weapon for mathematicians all over the world, and it is widely spread all over the world......"

"However, counting chips, it is even more difficult to refine the art, the general public, the posture of the middle, often exhaust their lives and cannot get their skins......"

"In the lower view, I sigh for the world, but I make an 'abacus', so that the world can ...... the home of mathematics"

Zhang Yue said and raised the abacus in his hand.

Naturally, everyone had already noticed the strange artifact in his hand, which was made of wooden beads, wooden beams, and wooden frames.

Every time he answered a question from Xu Hui and others before, he would pluck the beads of this thing, and then the answer came out.

Some people have already guessed that this thing is closely related to computing.

It's just, no one knows, how does it work?

Even more unknown, how is it calculated?

At this moment, hearing Zhang Yue take the initiative to mention it, everyone immediately concentrated on it, concentrated all their attention, and operated every cell of the brain.

The whole world was silent only for Zhang Yue's voice and the occasional sound of the wind blowing on the branches.

"Abacus, divided into two columns...... Zhang Yue raised the abacus in his hand and introduced: "Upper beam beads two, lower beam beads five, a total of eleven beams, where seventy-seven beads ......"

"The upper bead is one and the lower bead is five ......"

"Starting from the first beam, it has been listed as a ...... of 100,000,000,000,000,000,000,000,000,000,000,000,000,000,00

Zhang Yue put the abacus down, and at this moment, in the eyes of everyone, this ordinary, unremarkable, and extremely simple abacus has become a treasure that is far more precious than any treasure in the world.

Just Zhang Yue's introduction has already made them understand one thing - a brand new calculation tool that far surpasses the old calculation chips has been born!

Get it! Learn it! Master it!

Everyone roared in their hearts!

The scholars of the poor family were even more excited, and their faces flushed.

Because, this thing will definitely be popular in the world!

And the first person to get it, learn it, and master how to use it, even if it is a pig, can counterattack and mix well.

Three Princes and Nine Secretaries, Chang'an Offices, and the Princes of Tianxia Prefectures and Counties......

In the future, there will be a large demand and thirst for talents who can skillfully use this material for computing!

And the future of myself and others is already suddenly bright, and there are no more ups and downs!

"The use of this thing is also very simple......

Zhang Yue continued to introduce, while calmly observing the many scholars to find the talents that could be created.

The use of abacus and formulas, Zhang Yue will not hide his secrets.

He doesn't have the so-called small family spirit of everyone and family in this era.

Will deliberately leave behind and cover up some of their own things.

So as to benefit one family and one surname.

But they didn't know that these practices of theirs had caused a result that they would not want to see - the brainchild of the sages was finally in vain.

The technology, knowledge and classics that once shone in the long river of history were finally buried deep in the ground, sleeping with dry bones and accompanied by loess.

For example, "Sun Bin's Art of War" was lost for 2,000 years, and finally it was in New China that it was dug up from the Mawangdui in Changsha and reappeared in the world.

But, at that time, what was the value of this art of war?

It's just a display in a museum for future generations to admire and appreciate.

What's even more ridiculous is that because of some people's selfish desires, Confucianism even "Analects", "Book of Filial Piety", "Book of Songs" and "Book of Shang" are incomplete.

These texts have a large number of passages that have been marked as 'lost' in later generations.

I want Confucius to establish a school back then, there is no class of teaching, and those who come do not refuse.

But the disciples and grandchildren swept away their own treasures and hid them.

I'm afraid that someone else will find out.

Knowledge and technology, if not promoted and applied.

What do you do by inventing them?

Moreover, it has been proven that only the diffusion of knowledge and technology can bring real benefits to those who invent and create them!

If Ma Yun engaged in Alipay in later generations, he only let himself use it alone......

Then how to build his Ali empire?

Therefore, Zhang Yue will definitely not hide his secrets.

At least, the basic functions of the abacus and the basic calculation formulas, he will not hide.

On the contrary, he will do his best to promote and publicize it with all his might.

Let more people learn and use them.

The more people who use it, the greater his fame, the greater his fame, the higher his status, the higher his status, the better his life.

It is more Keze and his descendants, and it lasts forever.

But there are some things that he will only teach to those he chooses for the time being.

These things are the Arabic numerals that people are familiar with in later generations, as well as some simple mathematical formulas and symbols.

It's not because I want to hide it.

Instead, Zhang Yue knew that in this era, rashly proposing some new knowledge and new symbols might be attacked as a 'tricky person', and might even be demonized.

Just in case, before their own wings are full, these things will only be taught to those who can be trusted.

Who can be trusted?

Brain-dead fans and die-hard fans!

And what Zhang Yue has to do now is to find out those trustworthy brain-dead fans from more than 200 people through observation, contact and understanding.

By co-opting and helping these people, they gradually build up their own small groups.

Zhang Yue observed the crowd while demonstrating the use of the abacus.

"If one adds one, it is one on the ......"

"Every ten plus one, it is one up five to four, one to nine into one ......"

"Add two, two on two, two down five to three, two to eight into one......"

"Add three, three on three, three down five to two, three to seven into one......"

……………………

With Zhang Yue's narration and demonstration, everyone present only felt that a new door was being slowly pushed open in front of them, and a new world, a new world of mathematics, vast and boundless, was displayed in front of everyone.

Mathematics, once a difficult and obscure field that is difficult for ordinary people to know and calculate, has cracked.

After having an abacus, from now on, people from humble families and middle-aged people may be able to talk and laugh at mathematics and guide arithmetic like elites.

In the past, the era of relying on calculations to carry out tedious and brain-wracking calculations may be gone!

And I and others were fortunate enough to be among the first to learn and use this new tool.

As long as you learn it, it is equivalent to having a magic skill that can be used as a family heirloom!

Everyone is excited, and it is difficult to restrain themselves.

And Zhang Yue didn't care about this, just talked slowly.

Finish the use of mantras and methods of addition and reduction on the abacus.

He stopped and asked, "Have you remembered everything?" ”

Naturally, there are many people who are immersed in surprise and shock, and they don't remember it all at all.

Immediately beat his chest and stomped, regretful.

I thought I had missed this once-in-a-lifetime opportunity!

And those who are engrossed in it, concentrate on it, and write down every word on the bamboo slips, immediately protect their books like a hen protecting her chicks.

"If I don't remember it, I'll say it again......"

"Zhang Shengdade!" Suddenly, countless people threw themselves on the ground and bowed to it!

In today's world, even teachers may not be so intimate to explain and demonstrate to their students again and again.

You didn't remember when the teacher was lecturing?

Do you want the teacher to talk about it again?

No way!

Teacher's lecture desertion?

Rotten wood cannot be carved, what is the use of you?

Zhang Yue smiled slightly, didn't mind it at all, and talked about the addition and multiplication formulas again.

Then, he picked up the abacus, and in front of everyone's eyes, his hands were like lightning, constantly moving the abacus, and his mouth continued to recite the abacus mantra.

Crackling, a burst of operation, but in a matter of moments, he completed the process of adding from one to ten, and then from ten to one.

At this moment, everyone understood why Zhang Yue was answering Xu Hui and others to move the abacus.

It turned out that he was calculating at that time!

And this kind of computing efficiency and method is simply amazing!

If you can do the same yourself, then ......

Countless people have dreamed of it, and they have fallen into illusions about a bright future.

"The way of abacus lies in practice makes perfect, you and others are looking for someone to make an abacus, practice day and night, three days later, a certain time to talk about the way of multiplication and division......" Zhang Yue picked up the abacus, stood up and said.

Of course, Zhang Yue will not finish this abacus at one time.

How can you build up your prestige and hype yourself up like this?

In these years, how can it become popular without hype?

When everyone heard this, they got up one after another, bowed respectfully, and respected: "Congratulations to Zhang Jun (Zhang Gong) ......"

Until this time, all the scholars and nobles were impressed by Zhang Yue.

Generous and righteous, patient and fair.

Such a person is not a gentleman, who is still a gentleman?

Yuan Chang immediately followed behind Zhang Yue, like a little daughter-in-law, and bowed softly: "The disciple often sends the teacher ......."

"Ahem......" Zhang Yue only felt a little twitching on his face, this thing is really sticking to himself!

In the face of such a shameless and rich kraft candy, Zhang Yue has nothing to do for the time being.

It can only be with an attitude of not admitting and denying it.

As for Xu Hui and the others, the eyes looking at Zhang Yue at this moment have completely changed.

"Tianzhong Wizard......" Xu Hui got up, dusted off his clothes, and looked at Zhang Yue's eyes that were even full of admiration.

Just the matter of solving pi has already made Xu Hui know that it is impossible for him to catch up with this Zhang Zizhong's back in his lifetime.

You can only look up to each other!

And as soon as this abacus and abacus mantra came out, he understood even more that he might not even have the qualifications to look up to the other party!

What to do?

Confucius said, shame and courage!

Under the influence of the idea of great revenge, the self-esteem and shame of the Han family doctor are particularly strong.

Different from the fur that later generations of neon learned.

For the Han Chinese, it is a shame to be defeated.

After being humiliated, the first reaction is to fight back.

If you counterattack, you find that you are not the opponent's opponent anyway.

Then, learning from the other party and taking the other party as a teacher has become the last option for this person.

Learn from his strengths, learn from his thoughts, culture, and technology.

Transform yourself in this way.

In the end, it can be defeated!

That's the way to go!

For example, Zhao Wuling King Hu Fu rode and shot, and ram scholars all over the world praised it, thinking that this was the trip of the Holy King.

The Han family was suppressed by the Hun cavalry before today.

As a result, the Han army also took the initiative to learn and imitate the Hun cavalry, and formed a large number of field cavalry units.

In the first year of Yuanguang, the general Wei Qing led the Han cavalry to take the initiative to attack the heart of the Xiongnu, which opened the prelude to the Han-Hungarian War!

Therefore, just after hesitating, Xu Hui firmly followed Yuan Chang, and attached his tail behind Zhang Yue, like a concubine, with low eyebrows and obedient eyes, serving left and right as a disciple.

After Xu Hui, Wu Yuan also gritted his teeth and followed.

Then, the other people looked at each other, and they all bowed their heads and followed.

And this is exactly the spiritual outlook of the scholars of this era!

Failure and setbacks are not terrible!

Jonny has experienced setbacks, traveled the world and no one has used it.

Mencius also traveled around the world and was disliked.

Even Xunzi was humiliated when he entered Qin.

However......

Now, who is the winner? Who is the ruler?

Failure and setbacks are not shameful, on the contrary, this is grinding, this is motivation, this is encouragement, this is the only way to grow up.

No one is depressed by their failures and setbacks.

For the Han people, what is truly terrible is never failure.

Goujian, the king of Yue, had nothing to lose.

But he tried his courage in lying on his salary, ten years of life, ten years of lessons, once shameful, and the world admired him.

The state of Chu was also defeated.

However, although Chu has three households, the death of Qin will be Chu!

Xiang Yu's soldiers entered Xianyang, and a fire burned the pride and honor of the Qin people!

The Huns also used to show off their might by the Great Wall.

But what about now?

Alone in the north of the desert, he can only rely on the natural dangers of the desert to survive.

The Han army drove straight in, and there was no royal court in the south of the curtain.

When Yi Di saw the Han people, he didn't even dare to bend his bow to each other!

In recent years, Fang Dare occasionally came out of the Hanhai Sea and harassed the Han family.

But, they can no longer threaten the Great Wall!

The Han army has already burned the flames of war to the lair and hinterland of the Huns!

And all these facts have told the Han scholars a fact - it doesn't matter if the skills are not as good as others, and it doesn't matter if they fail.

As long as there is a breath left, as long as the blood is not cold, there must be a way to take revenge on the shame!

If you are beaten, then you will fight back.

If you can't beat it, you can learn from each other.

Learn the knowledge and skills of your enemies or opponents, and beat them back!

Spring and Autumn said: Xianggong Fu Ninth Hatred!

Qu Zi said: The road is long, and I will go up and down to seek.

Yi Yun: Tianxingjian, a gentleman is self-improving!

Xingtian Dance is a dry relative, and the fierce ambition is always there!

And this is the Shilin style of the Han family.

Although, for Xu Hui and Wu Yuan, today's encounters and changes are far from revenge, until the other party falls.

But they did feel the gap between themselves and Zhang Yue.

I did feel a deep sense of powerlessness and humiliation.

To calm this shame, you need to make your waist straighten again.

The only and most correct choice for them is to learn from each other and take each other as a teacher.
