"The most important thing in mathematics is calculation..."

"Today, I and you all want to talk about this arithmetic plan..."

Zhang Yue sat under the shade of the tree and talked freely.

More than two hundred scholars around him listened with their ears and did not dare to miss a single sentence.

Even Yuan Chang stood beside his side obediently, and his followers and diners wrote quickly and recorded quickly.

"Ancient ancestors, knotting ropes to record things..." Zhang Yue said softly: "The rope head has become the first counting tool..."

"At the three generations, there were ancient kings who used calculations to calculate and count, and their method was to control vertical and horizontal lines. They advanced when they met hundreds of times. The secret said: One vertical and ten horizontal lines, one hundred standing and a thousand stalkers, one thousand tens of each other, one hundred equals..."

"This method has been passed down to this day and has been a good tool for numerologists all over the world, and has been widely spread throughout the world..."

"However, it is even more difficult to be skilled. The general public and the average person often spends his whole life without getting the basics..."

"I looked at it below and sighed about the world, so I made an 'abbreviation' to make a family of mathematics and techniques in the world..."

Zhang Yue said as he raised the abacus in his hand.

Naturally, everyone had long noticed the square and strange object in his hand, composed of wooden beads, wooden beams and wooden frames.

Every time he answered Xu Hui and others' questions, he would touch the beads of this creature and then answer them.

Someone has long guessed that this thing is closely related to calculations.

But no one knows how it works?

Even more unknown, how is it calculated?

At this moment, when Zhang Yue took the initiative to mention it, everyone immediately focused, focused all their attention, and circulated every cell in their brain.

The whole world is quiet only by Zhang Yue's voice and the occasional wind blowing the branches.

"Abacus, divided into two rows..." Zhang Yue raised the abacus in his hand and introduced it: "Two upper beams and five lower beams, a total of eleven beams, and seventy-seven pearls..."

"The top bead is one as the bottom bead is five..."

"Since the first beam, it has been listed with tens of tens of tens of tens of tens of millions of tens of millions of tens of millions of tens of millions of tens of millions of tens of millions of tens of millions of tens of millions of tens of millions of tens of millions of tens of millions of tens of millions of tens of millions of tens of millions of tens of millions of tens of millions of tens of millions of

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

Just Zhang Yue’s introduction just now made them understand one thing - a new computing tool far beyond the old calculations emerged!

Get it! Learn it! Master it!

Everyone yelled in their hearts!

The poor men were even more excited and their faces were flushed.

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

And the first person to get it, learn it, and master the use of it, even a pig, can counterattack and do well.

Three Dukes and Nine Ministers, Chang'an offices, the states and counties in the world...

In the future, there will definitely be a lot of demands and desires for talents who can use this thing for calculations!

And the future of my and others has become clear and there are no more bumps!

"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 can be created.

Zhang Yue will not hide his personal use and formulas of abacus.

He does not have the so-called grandfathers and aristocratic families of this era.

Some things that will deliberately leave behind and cover up.

This is to benefit one family.

But they didn't know that their actions had resulted in a result that they would not be willing to see - the fruits of the sages were finally gone.

Those technologies, knowledge and classics that once shined in the long river of history were eventually buried deep underground, sleeping with dry bones and accompanying the loess.

For example, "Sun Bin's Art of War" was lost for two thousand years, but it was finally dug out of the Mawangdui in Changsha and made it reappear in the world.

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

It is just displayed in a museum for future generations to admire and appreciate.

What’s even more ridiculous is that because of the selfish desires of some people, Confucianism is incomplete even the Analects of Confucius, the Book of Filial Piety, the Book of Songs, and the Book of Documents.

These classics have a large number of chapters marked as "lost" in later generations.

I remember that Confucius established his studies and had no distinction between teachings and no one would refuse.

But the disciples and grandchildren have treasured themselves and kept it hidden.

I was afraid that others would find out.

Knowledge and technology, if it cannot be promoted and applied.

What did they do invent?

Moreover, facts have proved that only by promoting knowledge and technology can we bring real benefits to those who invent and create them!

If Jack Ma made Alipay in later generations, he would just let himself use it alone...

Then how did his Ali Empire be built?

Therefore, Zhang Yue will definitely not hide his own private interests.

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

On the contrary, he will try his best to promote and promote it with all his efforts.

Let more people learn and use them.

The more people used, the greater his reputation, the greater his reputation, the higher his status, the higher his status, and the better his life.

It can benefit the descendants and will never last forever.

But for the time being, he will only teach the people he chooses.

These things are Arabic numerals and some simple mathematical formulas and symbols that people in later generations are well known.

The reason for doing this is not to hide your own private life.

But Zhang Yue knew that in this era, he would rashly propose some new knowledge and new symbols, and he might be attacked as a "single of strange skills and tricks" or even demonized.

In case, these things will be taught to those who can trust them for the time being before their wings are full.

Who can trust it?

Brainless fans and die-hard fans!

What Zhang Yue has to do now is to find those brainless fans who can be trusted from these more than 200 people through observation, contact and understanding.

By drawing and helping these people, we gradually build our own small groups.

While observing everyone, Zhang Yue demonstrated how to use the abacus.

"If one plus one, it is one on one..."

"Every ten plus one, one goes up to five and four, one goes up to nine and one goes up to one..."

"Add two, two on two, two on five on three, two on eight on one..."

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

………………………………………

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

Mathematics, a field that was once difficult to understand and difficult to calculate by ordinary people, has already appeared in cracks.

After having an abacus, from then on, poor people and middle-aged people will probably be able to talk and laugh at mathematics and give advice on arithmetic like elites.

In the past, the era of cumbersome and brain-hardening calculations that needed to rely on calculations was probably gone forever!

And I and others are fortunate to be the first to learn and use this brand new tool.

As long as you have completed your studies, you will have a magical skill that can be passed down from family and as the family background!

Everyone is surging and unable to suppress themselves.

Zhang Yue didn't care about these things and just talked about them slowly.

Finish the usage formulas and methods of addition and reduction on the abacus.

He stopped and asked, "Did you remember it?"

Of course, many people are immersed in surprise and shock and do not remember them all at all.

He immediately beat his chest and stamped his feet, regretting it.

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

Those who concentrate and concentrate on each word on the bamboo slips immediately protect their books like a hen protecting the chicken.

"Since I didn't remember, I'll just say it again..."
To be continued...
