Chapter 90 Datang Numbers (First Update)
PS. There are six more updates today, by the way, please order all!Thank you everyone!

"Li Chunfeng, what are you doing?"

Li Chunfeng took out a booklet from his arms.

and spread out.

Pointing to the words above, he said, "You wrote this?"

Li Min looked at it, wasn't it the problem he solved some time ago?
The numbers above are still pretty obvious.

25+x^2=(x+1)^2=X^2+2X+1
2X=25-1
2X = 24
x = 12
……

He didn't mean to hide either.

"Yeah, I figured it out at random after reading the topic that day. What's wrong?"

What a random thing, what else could he do?

"Sixth prince! Li Chunfeng is polite!"

Li Chunfeng knelt on the ground again and shouted.

You know, Li Chunfeng and Li Min don't know each other.

For more than half of the time, he Li Chunfeng was outside, and only occasionally went to see Li Shimin.

As for Li Min who was in the deep palace all the year round, he would never see him.

Li Min thought to himself, this is also possible?
Discovered so soon?

"How did you know my identity?"

Only then did Li Chunfeng say, "My subordinates read your problem-solving steps before, which are very clear and admirable.

A person wants to know, who is the solution to this problem, that is really a genius.Then he took this booklet and went to the palace to ask His Majesty to send someone to assist his subordinates in finding the person who answered the question.

I don't want Your Majesty to recognize your font, so I directly said that it was the Sixth Prince.Since that day, the subordinates have been inquiring about the sixth prince, but they have no clue. "

In this way, Li Yan understood a little.

Unexpectedly, Li Shimin could only understand his own words before concluding that it was his own.

So that means that when Kong Yingda collected the poems, Li Shimin also knew what he did?
It is good to dare to be affectionate, let Li Er know that his life is not bad, and it is still affecting the trend of Datang in a subtle way.

Make Datang stronger.

Prove yourself to make Datang stronger.

Let Li Shimin feel that he is inferior to himself.

Li Chunfeng is a chatterer.

He saw that Li Min did not speak.

He said again: "Today finally let someone find the sixth prince! It's really great!"

"What are you looking for from me?"

Li Min was puzzled.

He also didn't let Li Chunfeng get up. If this person wanted to kneel, let him kneel for a while longer.

But some talented people are some weirdos.

Li Chunfeng is no exception. If you let him get up, maybe he will be angry.

So go with him.

"Can you solve the problems in the nine chapters of arithmetic for me, and how your solution works? And what are these numbers?  …"

Li Chunfeng's questions were very intensive, all about professional questions, and there was no chance for Li Min to reply.

At this time, Zhu Shan walked in from outside.

As soon as he heard this, he said, "Li Chunfeng, if you ask that, how will the sixth prince respond to you? Which one will you respond to first?"

Only then did Li Chunfeng realize his negligence.

"Sorry, I'm a little excited. I want to ask these questions too much."

Li Min said:
"Come on, drink some four-fruit soup first, are you thirsty? As for your question, can I reply to you later?"

"Yes, yes, when the sixth prince wants to say it, he will say it. A wait."

The five people drank the four-fruit soup.

Cheng Chubi had drunk it, but still said it was good.

Fang Yi'ai exclaimed in amazement after taking a sip.

Do you still ask?Can I get him to drink more.

Li Min said that if he wants to drink, he has enough.

As for Li Chunfeng drinking, he was thinking about the problem.

It would be a waste for such a person to give him such a good thing, and his heart is here at all.

Li Min sighed.

I thought to myself, maybe I can teach him something first, and then teach him slowly about the problem-solving later.

such as Arabic numerals.

So, he and Li Chunfeng said: "Li Chunfeng, come here, I will write a few words to teach you."

Li Chunfeng put down the bowl and followed.

Later, Li Min wrote on the paper: 1234567890
Ten Arabic numerals.

Faced with such simple and incomprehensible numbers.

Everyone was puzzled.

Except for 1, everyone else may not know it.

Because 1 is like a horizontal one.

Cheng Chubi pointed at 0 and said: Is this an egg?What a circle!

If this is an egg, how should 689 be explained?

Li Min rolled his eyes at him.

Don't talk nonsense if you don't understand.

"It's Arabic numerals," he explained.

Numbers are the foundation of mathematics. To establish a complete scientific system, simple numbers are essential!

The most suitable numbers are Arabic numerals.

It is of great significance to life, industry, agriculture and other aspects!

With it, all aspects of Datang will be more convenient in the future.

I happened to meet Li Chunfeng.

He can advise in front of Li Shimin.

Top-down propaganda from Li Shimin.

It's definitely not enough to do this by yourself. He only provides ideas, and if he is tired, he will give it to others.

So, as long as he is taught, everything will be easy.

"Why is it called Arab, and where is that? Or is it an uncle named Arab?"

Li Chunfeng considers himself to be erudite, but he doesn't know there is such a place as Arabia.Even understood as a person.

Only then did Li Min realize that it was a little too out of touch.

So he said: "Somewhere in Dashi, as for the name, it is the title. In the future, we will call it Datang Numbers, so that it can be better explained."

"It turns out that someone has seen the figures of Dashi from an ancient book, but it's not like what you drew."

That's of course, he's writing about future-improved numbers.

How could he, a Tang Dynasty person, know?
"Yes, I invented this math."

Li Min simply said so.

As soon as his words came out, the crowd was full of admiration. In their hearts, Li Min was really almighty.

"The sixth prince is really powerful, so what do these numbers represent? Can you explain the Tang numbers for someone?"

"Naturally."

They have decided to teach him, and they will naturally teach them well.

Next, we have to use Li Chunfeng to promote it, so Li Min simply taught him all.

So he began to explain ten Tang figures for Li Chunfeng, and explained the combinations of them, such as ten million, ten thousand, ten thousand, and so on.

The more he talked, the more excited Li Chunfeng heard.

This Li Chunfeng is really a genius.

Just listened to it once and remembered it all.

In the end, Li Chunfeng said: "This Great Tang figure is really exquisite."

Then Li Min began to explain to him the use of addition, subtraction, multiplication and division symbols, which made him agree.

It has to be said that Arabic numerals do have an absolute advantage in calculation.

Only one and only!There is no other number in the world as convenient as it is.

After a long time, Li Min taught Li Chunfeng some equations and explained the previous topic.

Li Chunfeng stayed here all day.

Li Min also likes this kind of studious person.

For the next few days, Li Chunfeng stayed in the Shengtang Group until late at night before leaving.

Li Chunfeng also said that he must talk to Li Shimin about this matter, and he must vigorously promote the opening of Datang figures.

He didn't say it casually. In the afternoon, Li Chunfeng went to Tai Chi Palace.
