Datang: Let you supervise the country and become an emperor through the ages

Chapter 255 Great Praise
At this moment, Li Gang really doubted whether God was blind, could it be that Li Fu is God's illegitimate child?

But no matter what, Li Gang couldn't help admitting that the nine-nine-nine multiplication table and multiplication column calculation that he was shocked by were all created by Li Fu.

Moreover, Li Gang really had some details and needed to consult Li Fu, so he immediately went to Li Fu to pay respects.

"His Royal Highness, the old man has already seen your multiplication calculations. It is really unpredictable. At the same time, it can greatly improve the calculation speed of the current Tang Dynasty. It is really amazing. Please pay respects to the old man."

Li Fu looked surprised, "So, sir, you have already seen it, the nine-nine multiplication table and column calculation?"

"That's natural, but the old man is a little puzzled, and I want to ask His Highness the Crown Prince to give me some advice, and I hope His Majesty the Crown Prince will help you!" Li Gang kowtowed to Li Fu with a 'boom' sound.

Li Fu is really not in the mood to watch this old man do elementary school math problems for him, but he kowtows to you and begs you to help him with his age. Tempered to watch Li Gang demonstrate to him.

Seeing that Li Gang took the pen and paper and began to calculate the multiplication formula of two numbers for him, Li Fu was speechless for a while.

[Fuck, this is such a mess, I said I shouldn't be soft-hearted, Nima really has hot eyes! 】

[This is nothing, 120, 760, [-]. Isn’t it troublesome to calculate it by formula after writing it like this? 】

[Can't you use Arabic numerals?Just multiply 125 by 760?Isn't it more convenient to write this way? 】

Li Shimin naturally heard Li Fu's heartfelt voice. He was very happy to hear Li Fu complain about Li Gang, but after hearing Li Fu complain about Li Gang's inability to use Arabic numerals, Li Shimin's eyes suddenly straightened.

What are Arabic numerals? 125? 760?What is this all about?
However, with Li Shimin's intelligence, he can still guess that these should be the numbers used to replace 120 and 760, and Li Shimin found that if they are replaced in this way, the column calculation is really very convenient!

But Li Shimin knew that with Li Fu's personality, it was absolutely impossible to say it, and in the current situation, he could only let Li Fu say it naturally through his own guidance, so...

"Prince, do you see the vertical multiplication formula written by Mr. Li with 120 five and 760 columns, does it look awkward?"

"Do you think there is a way to simplify these numbers to facilitate multiplication calculations?"

After hearing Li Shimin's question, Li Fu couldn't help but take a deep look at Li Fu. He suddenly had the feeling that Li Shimin was a roundworm in his stomach.

Originally, he was too lazy to talk to Li Gang and Li Shimin, but seeing so many people in front of him, all looking at him eagerly, Li Fu could only nod and said: "Of course there are, Mr. Li Gang, please stop for a while."

"You don't need to list anymore. I have already seen that you have understood the calculation of columns, but according to your method of calculation, I am afraid that it is easy to make mistakes and waste paper. Why don't you try my method and directly use Arabic numerals instead Existing numbers?"

"Arabic numerals?" Li Gang was stunned for a moment, and Li Fu took the pen from his hand, and then wrote a line of numbers next to the formula he just listed.

"Arabic numerals are actually passed down from the Western Regions. It is a convenient way to express numbers. One is 1, two is 2... ten is 10, and so on. So your vertical formula just now can actually be listed like this!"

Li Fu quickly used Arabic numerals to list the vertical formula below Li Gang's formula, and then quickly completed the calculation.

After Li Gang saw the result, he was stunned, Li Shimin was also stunned, and the people present couldn't recover for a long time.

Everyone was dumbfounded, but Li Fu didn't show any arrogance, and let them carefully read the vertical form he had just written, giving them time to react.

After a long time, Li Tai was the first to realize, "Prince, according to what you mean, you can use this method to keep accounts and liquidate no matter what accounts you have in the future?"

What a young man!Li Fu nodded slightly, and gave Li Tai an affirmative nod, "That's right, but in order to prevent the accounts from being revised, some improvements are still needed, especially in terms of the result amount, it's best to replace it with capitalized numbers."

Afterwards, Li Fu wrote down the capitalization of numbers such as one, two, three, four, five, etc. on the white paper. At this time, Li Shimin and others finally came to their senses.

After listening to Li Fu's introduction, Li Gang's eyes shone brightly, "His Royal Highness the Crown Prince is simply a genius in mathematics. As a result, our Datang's calculations and accounts will undergo earth-shaking changes. In the future, the accounting will be improved." Great simplification!”

"And according to the prince's way of writing, there is no possibility of any mistakes, unless it is artificial!"

Li Gang was completely excited at this time. After all, what Li Fu said would bring about earth-shaking changes to Shushu. This is definitely something worth celebrating for everyone who counts Shusu.

And Fang Xuanling, Xiao Yu and the others couldn't help but be amazed and praised Li Fu greatly.

"Originally, His Royal Highness improved papermaking and printing, and it has become very convenient for me to deal with official duties."

"Now His Royal Highness has created Arabic numerals and uppercase numerals, which will become more convenient and accurate for us to handle the official affairs of the Ministry of Finance!"

Li Fu smiled lightly, "The chancellor is too famous, I just learned about it from the merchants in the Western Regions when I was free."

Li Shimin shook his head and said: "That is also your credit, Prince, there are not a few merchants from the Western Regions in Chang'an, but you are the only one who has researched matters related to calculations and numbers. This is your great credit! "

Li Fu couldn't accept Li Shimin's words at all, he could only agree with what he said.

"Hahaha... With these Arabic numerals, the old man will make rapid progress in the calculation. Thank you His Royal Highness, the old man is bothering me, so I will resign! After all, Li Gang actually left as soon as he said.

In Li Gang's heart, there is nothing more important than learning. Now he is eager to summarize what he has learned in the past two days.

Ninety-nine multiplication tables, multiplication column calculations, and Arabic numerals and uppercase numbers just learned!

Li Gang can feel that his future achievements lie in what Li Fu said.

Li Gang had just left, and before Li Shimin and the others left, the door to the side hall of Li Fu's hall suddenly opened, and a young woman came out.

"Princess Huayan?" Seeing the woman's face, Li Shimin, Fang Xuanling and others were shocked.
