God-level prince of the Tang Dynasty

Chapter 318 How Much Is Seven Times Eight? (first update)
Thanks to: book friends Xiaoxiaowei, Jiu Lixuan for the reward!
The next day, when Li Chengqian got up early, he heard someone come in and preach: "His Royal Highness, Your Majesty welcomes you!"

This early in the morning, I have to let myself go, is it because of the Arabic numerals?
This must be the case, Li Chengqian looked at the sky, and the court probably was about to end at this time.

Or, go to the Tai Chi Palace for a walk.

So he took Xue Rengui to Tai Chi Palace.

As soon as he entered the palace, the civil and military forces of the Manchu Dynasty had already left the court, and only Li Shimin, Kong Yingda, Changsun Wuji, Hou Junji and others were left present.

The others were not there for a long time, it was hard to pretend, how could those people be missing?Really depressed.

As soon as he saw Li Shimin, he saluted and said, "I have seen Your Majesty!"

Everyone also said: "I have seen His Royal Highness the Prince!"

Seeing that Kong Yingda was there, Li Chengqian probably knew what was going on.

Li Shimin first said: "Gao Ming, Kong Yingda said that you brought a thing called Arabic numerals, which is very useful, let us promote it?"

Before Li Chengqian could reply, Changsun Wuji said: "His Royal Highness must think that I am not good at Tang mathematics, so I introduced these numbers from Bangbang, right?"

Where is Arabia?No one knows, but once it is a place other than Datang, they will be called Fanbang by them.

This hat is really big when it is buckled down.

But Li Chengqian said in a down-to-earth manner: "After all, the mathematics of my Tang Dynasty is a bit difficult to learn, and it is not convenient enough, and the algorithms for solving questions and answering questions are complicated."

Arabic numerals can become a globally unified number in later generations, which must have its huge advantages.

Not to mention anything else, but in terms of the convenience of writing, it is absolutely irreplaceable by other numbers.

Hou Junji said: "I thought that the Mathematics of the Tang Dynasty is fine, and there is no need to promote the mathematics of other countries. It really makes others angry and destroys one's own prestige!"

"It should be someone else's advanced, we have to learn from it, so that we can be strong! This king's approach is to gather the great achievements of the world! You don't understand this truth, do you?"

Kong Yingda also said: "Hou Shangshu's words are wrong. The so-called three-person walk must have my teacher. This Tianzhu number is so convenient. We should learn from it and promote it in the world. Let everyone in the world learn it and think that life Convenience provided!"

Li Chengqian smiled, and asked: "Qi Guogong, Hou Shangshu, do you understand mathematics?"

When the two were asked like this, they were immediately stunned, what do you understand?This is obviously looking down on them.

Changsun Wuji said: "I have been familiar with Jiujiuge since I was a child! I have a little research on mathematics."

Multiplication formulas (also called "Nine Nine Songs") have been produced very early.As far back as the Spring and Autumn Period and the Warring States Period, Jiujiuge has been widely used by people.

In many works at that time, some multiplication formulas have been quoted.The original Jiujiuge started with "Jiujiu 81", just like Monkey King's Jiujiu 81 transformation, and the subsequent Qiqi 49 days, Sanqi 21, these are the contents of Jiujiuge.

Changsun Wuji really dared to talk about something as elementary as Jiujiuge, and he dared to say that he had studied it, how shameless!

But it's okay, just test them casually, they probably won't do it if it's more difficult.

"Okay then, I'll give you three questions to solve, and see if you can solve them all. If you can solve them all, why don't I advocate carrying them out?"

Kong Yingda was a little nervous now, he was afraid that if the two answered, his plan would be ruined.

"There is nothing to worry about, they can't answer the third question!"

Looking down on the two of them so much made them very angry.

Hou Junji fully agreed: "It's possible, if His Royal Highness can stump us, we won't stop it anymore!"

"Where is Duke Qi?"

"So am I!"

"Your Majesty, please testify for us!"

Li Shimin said straightly: "It's possible, I also want to see if Bangbang's mathematics is really that good!"

"Alright then, listen up! There are eight people, seven Wen each, how much is the total?"

Changsun Wuji agreed first: "56 coins! Can you make it difficult!?"

At that time, there was no such thing as multiplication, and Changsun Wuji responded directly with Jiujiuge.

Also very arrogant.

Li Chengqian ignored it, and then escalated the question: "Eleven people, each with eleven coins, how much money do they have in total?"

At this time, everyone was silent. After all, Jiujiuge only reached the one place, not the ten place. When Li Chengqian got the ten place in the test, they were all stumped.

Finally, Hou Junji held his fingers there, and after a long time of calculations, he said, "But 120 pennies?"

After Changsun Wuji heard this, he laughed loudly and said, "That's right, it's 120 one! Hou Shangshu is indeed very powerful!"

"Very good, then next, listen carefully to this question!"

Everyone is all ears.

Li Chengqian said: "130 a person, each has 390 eight Wen, how much money is there in total?"

As soon as this question came out, everyone was stunned, it was already beyond the scope of their knowledge.

Changsun Wuji shouted: "How can this be calculated! Your Royal Highness, I am afraid that no one can calculate it?"

"That's right, how do you calculate so many numbers? His Royal Highness won't just say the numbers casually."

"You guys can't count, but this king can!"

After speaking, Li Chengqian walked to the side, took a piece of paper and a pen, and listed out the multiplication formula.

It only took a dozen seconds, and the result came out: 130!

When Li Shimin heard this, he quickly asked people to use calculations to figure out the result.

Counting chips is the counting method of counting chips in the decimal system in ancient China. It is a great creation in the history of mathematics in the world.

Probably after a long time.

Only then did someone report an answer.

"Your Majesty, the villain got the result: fifty-two thousand one hundred and thirty-eight"

When the result came out, everyone was shocked.

At the same time, it also brought him more than 100 points. He didn't look at these points at all. It's a pity that the ministers have left, otherwise there would be more.

Li Chengqian finally smiled and said: "How about it, do you think the mathematical value of this state is worth promoting?"

Don't wait for Changsun Wuji to say it.

Li Shimin said directly: "Push! Promote it directly!"

The convenience of this number had won him over.

With Li Shimin, it's worth it.

"Yes! Your Majesty, I will promote it together with the printing! And I will invite Master Confucius to be the host to carry out the promotion of the whole Tang Dynasty!"

"allow!"

In this way, the promotion of this mathematics is like this, which surprised him a little.

When he left the Tai Chi Palace, a reminder came to his head: Congratulations to the host for performing the mathematics promotion task!Extra bonus plus ten percent.

Um?This can be regarded as an unexpected joy, and it seems that we need to put more effort into education.

He didn't know that a conspiracy about how to destroy him was brewing in another place at this time.
