Daqin: I was overheard by Zulong

Chapter 245 That's Your Contribution, Prince

【Damn it, the old man really has a big mouth, he told Zhang Cang about the vertical calculation of multiplication so quickly! 】

[If you want to show off, you shouldn’t be so impatient, Nima, teach people more thoroughly! 】

Zhao Yi looked at Zhang Cang's bewildered look, and mistakenly thought that Zhang Cang didn't understand what Ying Zhengjiao taught, but he didn't expect that Zhang Cang was doubting life.

Now he is not only at a loss because of being deceived by Ying Zheng, but also has some doubts about life, and even begins to doubt his own IQ.

During the time he stayed with Zhao Yi, he often felt a deep sense of frustration.

I think he counted everyone from generation to generation, worked hard all his life, and dared not slacken the slightest slack every day, but he made little progress on the way of counting.

Look at Zhao Yi again. Not to mention that he sleeps until he is exposed to the sun every day, he has almost never seen him have the experience of reading.

But such a person can not only create a magic object like potatoes, but also create a calculation method that he can't match. This makes Zhang Cang start to doubt God, maybe Zhao Yi is God's illegitimate child!
But no matter what Zhang Cang thinks, the nine-nine multiplication formula and the vertical multiplication calculation are undoubtedly created by Zhao Yi.

After thinking about it, Zhang Cang decided to ask Zhao Yi for more advice, "The vertical calculation of multiplication created by the prince is really unpredictable. Not only can it greatly reduce the calculation time, but it can also be so simple, I admire you!"

Zhao Yi raised his eyebrows slightly, "Master Zhang, what do you mean, you have already learned the nine-nine multiplication formula and the vertical multiplication calculation?"

"Slightly successful." Zhang Cang looked complacent, and he did a calculation for Zhao Yi, and Zhao Yi couldn't refuse.

[Fuck, does this old guy understand human speech? Why is he more annoying than that old guy Ying Zheng? 】

[Labour and management obviously didn’t mean this, but he still had to force it. Who the hell wants to see you tossing this elementary school student! 】

[It's really speechless, hey, what is this, what is [-], what the hell, just kidding, this is how Ying Zheng taught Zhang Cang to do vertical calculations last night, what a talent! 】

[Don’t know how to use Arabic numerals?Uh, by the way, are there any Arabic numerals like this now? 】

When Zhao Yi complained about Zhang Cang, Ying Zheng, who came after hearing the news, stopped outside and had a look of astonishment in his eyes.

Arabic numerals, what are these?It sounds like something awesome.

Then numbers like '760' and '15' popped into Ying Zheng's mind, and his eyes suddenly lit up.

With Yingzheng's IQ, of course it can be seen that these so-called Arabic numerals that Zhao Yi thought of should be another shorthand way of writing Daqin numerals.

There is no doubt that this shorthand method can make calculations more convenient than before, so Ying Zheng suddenly became excited again, thinking that his decision to come here after getting the news was completely correct!
"Hey, Zhang Cang is here too, what are you doing?" Ying Zheng said with a dignified look, "Oh, I'm counting again, hey, Prince, I want to ask you, the way of writing seven and six zeros, Is there some trouble?"

"Do you have any good way to express this number in abbreviated form, so as to facilitate the calculation?"

When Zhao Yi saw Ying Zheng, he didn't even have time to complain about him, but when he heard Ying Zheng's question, he couldn't help being taken aback.

[This old man is really a roundworm in my stomach. Just as I thought of this, he asked such a question. 】

[Then watch my next performance and let Zhang Cang see what I am capable of! 】

"Report to Father, yes." Zhao Yi nodded, signaled Zhang Cang to stop, and then said: "The current way of writing numbers is really cumbersome. If you use Arabic numerals, it will be much simpler!"

Arabic numerals?Zhang Cang was dumbfounded for a moment, what is this?
Zhao Yi picked up the pen casually, and began to signal to Zhang Cang and Ying Zheng, "Arabic numerals are a unique way of expressing numbers that I learned from businessmen from the big food countries in the Western Regions."

"For example, one, they use '1' to represent, two is '2' and so on 3456789, so the calculation of Mr. Zhang just now can be written as 760 multiplied by 15, and then the column formula can be written like this..."

Zhao Yi listed the vertical formula three times, and then quickly finished the calculation process. When Zhang Cang and Ying Zheng saw Zhao Yi's writing method, their eyes widened instantly.

And Zhi Li Naishi, who was almost invisible all the time, opened his mouth wide and let out an unbelievable exclamation.

"Oh my god, it's okay to count? This is too..."

Zhao Yi looked at the dumbfounded expressions of the ministers and emperors in front of him. He laughed, dropped his pen and put his hands behind his back, giving them time to calm down.

After a long time, Zhi Li Nei Shi rushed to Zhao Yi and asked: "His Royal Highness, according to your intention, in the future, we can count all the way, and those cumbersome numbers can be replaced by this expression of Arabic numerals?"

"This method is naturally suitable for simple settlements, but if it needs to be kept confidential or cannot be modified, the current method should be used..."

Hearing Zhao Yi's explanation, Zhi Li Neishi and the others were mesmerized, and they were all shocked again.

"His Royal Highness is simply a god-man. In this way, my Daqin will make great progress in the calculation!"

"Yes, this will be of great benefit to the development of our Great Qin. Wonderful, wonderful!"

Both Zhi Li Neishi and Zhang Cang looked excited at the moment, and Ying Zheng nodded repeatedly.

"Originally, His Royal Highness improved printing and invented paper making, allowing us to handle official business much faster and easier than before. Now he has created Arabic numerals, which undoubtedly makes it easier for us to handle official business!"

"You guys don't seem to understand what I just said." Zhao Yi said with a faint smile, "Arabic numerals were told to me by a businessman from the Dashi Kingdom. I just relayed them to you. Whether you need them or not is up to you."

"That's also your credit, Prince." Ying Zheng waved his hand and said with a smile: "In Xianyang City, there are so many businessmen from the Western Regions!"

"But why so many people don't know it, but you know it, Prince? From this, I can see that the progress of anything must be done with care."

Ying Zheng's words were indeed impeccable, and Zhao Yi didn't bother to defend himself, so he went with Ying Zheng.

"That's right. With these Arabic numerals, I will make great progress by leaps and bounds!" Zhang Cang laughed and bowed to Zhao Yi to the end.

"Then Your Highness, I will take my leave first!"

As he said that, Zhang Cang was about to leave. In his heart, he was already on the way of counting, and he had some insight, and wanted to verify it quickly.
