Jiujiang, in a house in Hefei.

Chu Feng stood at the front, he was lecturing at the moment, and he could be regarded as a training teacher, most of them were children from poor families, and there were also some children from families.

At the moment they dare not be serious,

Because Lu Su, Zhang Zhao, Jia Xu, Tian Feng, and Fu Zhu all listened carefully, the more they listened, the more frightened they became, the knowledge conveyed by Chu Feng was indeed too terrifying,

Especially the pinyin literacy, they found that it is too necessary to help enlightenment education, put aside the original cognition, the use of pinyin can have some results in just a few days,

It is estimated that teaching children with slightly stronger learning ability can learn it in a month.

Lu Su and the others were all impressed by Chu Feng's thing, they knew Chu Feng's literacy method when they taught it before, but now they are learning it in person, which is really powerful.

None of the sages of this law can be compared.

Chu Feng's name was destined to become the most dazzling existence in the annals of history, and they were even more looking forward to how these things proposed by Chu Feng would be carried forward in their hands.

"Ladies and gentlemen, pinyin needs a lot of practice, go back and communicate with each other privately, today in addition to pinyin, will also teach you new things."

Chu Feng erased the pinyin and looked at everyone solemnly.

Hearing that Chu Feng still had something to teach, it instantly made everyone's eyes hot, especially Lu Su Jia Xu and others at the front, who were gearing up one by one.

They call themselves the wise men of this world,

But in front of Chu Feng, they felt how narrow and small their cognition was, and they were not at the same level as Chu Feng at all.

For the things that Chu Feng taught, they were even more eager to have them, and none of them would have been found in these history books.

And among the following students, there is also a special person, Zhuge Liang. After he was controlled by Chu Feng, he took the initiative to ask to come to Yangzhou.

Of course, it is also possible that Chu Feng won against Yuan Shao.

After all, if you don't go out of the mountain, it is very likely that it will have nothing to do with you, especially if you don't have the opportunity to take refuge with other princes.

What's more, he is also clear about Chu Feng's deeds,

He admired Chu Feng's talent, so he came to Yangzhou.

As soon as he arrived here, he learned about Chu Feng's imperial examination system and enlightenment education, which put aside his family identity, Chu Feng's move was definitely forward-looking.

Historical development is destined to come to this point,

But Chu Feng let this step come in advance.

"Lord, dare to ask what is new?" Tian Feng was eager to ask, this pinyin had benefited him a lot, and he was even more curious about what the new things were.

"Arithmetic!" Chu Feng chuckled.

"In daily life, in addition to reading and writing, you also need to have a certain basic arithmetic ability, and the arithmetic summarized by the sages is the nine-chapter arithmetic."

"This algorithm is indeed the crystallization of human wisdom, but it is not convenient enough, it is not convenient enough." Chu Feng opened his mouth to be Wang Zhan, and directly denied the nine chapters of arithmetic that had been circulated.

Or rather, questioned,

You must know that any great power is based on the arithmetic of the nine chapters as the basis for ordinary operations, and Chu Feng said no, feeling that he is more complicated and inconvenient,

Dare to question the sages, and it is such a book, one word, awesome!

It's time for everyone else to be scared,

[My father is Yuan Shu? But I want to be a thief] 【】

But this was said by Chu Feng, and they faintly looked forward to it.

Of course, Chu Feng also has enough confidence to say this, mathematics has been developed for countless years in later generations, maybe there are some desirable places in the nine chapters of arithmetic,

But the vast majority of them are not as simple and easy to understand as the basic mathematics of later generations.

As he spoke, Chu Feng wrote Chinese characters from one to ten on the blackboard, and then wrote Arabic numerals from one to ten below, which they didn't recognize.

"These are numbers, each of which corresponds to our Chinese characters above, one, two, three, four, etc., which you can understand as abbreviation, which is convenient for calculation."

Chu Feng saw that everyone was surprised, and immediately explained.

"The use of basic arithmetic is nothing more than addition, subtraction, multiplication and division, addition and subtraction may not be difficult to understand, while multiplication and division is more complicated, especially with other algorithms are not easy to get results."

"For example, Lu Su, your family has fifty-seven acres of land, and each acre of land has thirty-five buckets of grain, how much grain can the family collect during this autumn's harvest, who can quickly calculate this?"

Chu Feng looked at everyone and said with a warm smile.

As soon as these words came out, everyone picked up the straw paper in front of them and began to calculate, but before this kind of arithmetic did not have a simple algorithm, the operation was too complicated.

For a while, many people frowned,

Lu Su raised his eyebrows, Jia Xu and the others were also pondering, several people were embarrassed to write, and they all wanted to try mental arithmetic, after all, the five of them were all great sages.

At this time, whoever writes is embarrassed,

It's just that this amount of computation is relatively large.

Without waiting for Lu Su and the others to react, Zhuge Liang raised his hand, he was not very old but his face was calm, and he was eight feet tall, and he was indeed handsome.

"Back to the lord, the Lu Su family harvests 1,995 buckets of grain in the autumn."

Chu Feng: "??? ”

Chu Feng was depressed, he wanted to pretend to be a force,

But this Zhuge Liang is really a little fucking demonic, but he paid attention to Zhuge Liang, and he didn't mention the pen from beginning to end, that is to say, he multiplied two digits in his mind,

The key is to be able to get the answer so quickly and accurately,

This made Chu Feng a little unconfident, why did he feel that mathematics was not as good as Zhuge Liang's mental arithmetic, he would definitely not be able to calculate this thing in a short period of time.

You have to do the math,

"Who is this person and why is he so powerful?"

"Zhuge family, Xuzhou clan, it is said that the lord takes special care of him,"

"Tsk, the lord is really as wise as a torch, I'm afraid this talent is not simple!"

Everyone kept talking, Jia Xu Lusu also looked at Zhuge Liang, they were all mentally calculated, and they couldn't compare to a stinky kid, which made their faces dull.

But then again, Zhuge Liang's performance is indeed worthy of Chu Feng's many mentions at the beginning, I am afraid that this person's intelligence will definitely not be below them in time, or even higher.

As far as this mental arithmetic is concerned, few people can match,

"Kong Ming, how did you calculate so fast?" Chu Feng was a little curious, no wonder Zhuge Liang could govern the country in an orderly manner, including the war later.

This IQ is really not bragging,

Everyone also looked at Zhuge Liang, a little curious.

"It's just mental arithmetic, and the algorithm of the lord must be faster than mental arithmetic, and there will be no ugliness in the next." Zhuge Liang smiled mildly and did not answer.

But this stumped Chu Feng,

[My father is Yuan Shu? But I want to be a thief] 【】

My algorithm is really fast, but it's far worse than you.

However, thinking that Zhuge Liang is rare for thousands of years, he naturally can't be compared with him, and the algorithm must be the actual ease of use in later generations, so he immediately said: "Of course, the algorithm also divides people." ”

"As for the speed and slowness, the algorithm I am talking about is that ordinary people can quickly calculate something, so that many things will not be confused for many days."

Speaking of this, Chu Feng listed the two numbers just now, fifty-seven at the top and thirty-five at the bottom.

"The next five..."Chu Feng used his strength to explain the process, but he always felt that what he said was unsatisfactory, he only seemed to remember the calculation process,

I can't remember how the teacher taught me at the beginning.

Grandma's, learn to use time to hate less, this is too annoying!

Trying to think about it, it was divided into ten single digits and so on, in short, the students taught were confused, and they were all a little dizzy, but Zhuge Liang's eyes flashed,

His mental arithmetic is only limited to multiplying two-digit numbers, and he can't do three-digit numbers at all, but looking at Chu Fenglie's arithmetic process, many things appear in his mind,

He vaguely seemed to understand what Chu Feng was watching,

Immediately, he picked up his pen and calculated according to what Chu Feng wrote, this time he didn't try to do mental arithmetic by himself, but wrote two numbers casually, and then calculated according to Chu Feng's process.

When solving the problem, the difficulty decreases sharply.

Because it's all a few times a few, which is hardly any difficulty, and then adds zero to tens of hundreds of digits, and then he quickly lists a few numbers.

Add them up in turn, looking at the answer, his pupils shrank suddenly, and the whole person showed ecstasy, the arithmetic taught by Chu Feng may not be as fast as his mental arithmetic,

But mental arithmetic is too restrictive, and ordinary people don't have this ability at all.

In other words, if the thing listed by Chu Feng can really be understood, I am afraid that it will far surpass any arithmetic method before the ancient times, and the speed will also be greatly improved.

As for multiplying one-digit numbers, they can all get the answer, that is, theoretically, even if it is three times three or even four times four, as long as the steps are correct, they can be calculated.

Thinking of this, Zhuge Liang's pupils were shocked,

It's too strong, Chu Feng can make the enemy frightened when he fights, the economy is strong and powerful, and the army is even more screaming, and he is invincible when he studies all kinds of things.

Now, even these things are far beyond the sages, which can't help but make Zhuge Liang's eyes hot, he has been smart since he was a child, and he can even remember it.

Other people's study books are full,

But the books in his study had already been emptied, they were all in his mind, he looked for books everywhere to read, but he gained very little, but until just now, he found that Chu Feng was a walking ancient book,

I'm afraid he'll find more in him what he wants to know,

Immediately, he wrote a three-digit multiplication, because there are 100 million Chinese characters, and he will soon be able to bring the following zero faster operation.

Hundreds, three, tens, three, and units,

Then quickly add and subtract, and according to what Chu Feng said, there is a carry position, Zhuge Liang's brain is running rapidly, in fact, the decomposition is the multiplication, division, addition and subtraction between the single digits,

It's just that you need to count zero later,

It is relatively fast to decompose and operate, Zhuge Liang's brain is running rapidly, and then he adds it quickly, and he only used dozens of breaths to multiply and divide a three-digit number.

[My father is Yuan Shu? But I want to be a thief] 【】

Looking at the final answer, he took a deep breath,

He didn't know if the answer was correct, but he instinctively told himself that it was the correct answer.

Zhuge Liang began to use his own method to verify, if there is no problem with this answer, then he dares to be sure, even in the past thousand years, no one can surpass this algorithm,

It's so convenient, it's too fast.

He couldn't calculate the three-digit number, and even if he did the pen, he had to list a lot of drafts to figure it out, after all, the multiplication and division of the three-digit number involved more things.

But it only took him a few dozen breaths to get the answer just now.

This speed is enough to subvert his cognition!

PS: "The next five..."Chu Feng used his boss to explain the process, but he always felt that what he said was unsatisfactory, he only seemed to remember the operation process,

I can't remember how the teacher taught me at the beginning.
