Datang Storyteller: Uncovering the Secret of Xuanwu Gate, Li Er was stunned

"This... this is really true!"

Wei Zheng held the paper handed over by Qin Yu, his hands trembling and his expression excited.

Qin Yu looked at Wei Zheng's reaction with satisfaction. After all, this form is intuitive and the data is clear and clear at a glance. It completely overturned Datang's previous bookkeeping method. Anyone who read it would have this reaction.

Qin Yu straightened his back, waiting for Wei Zheng to praise him.

As a result, Wei Zheng only trembled while holding the paper, with a puzzled look on his face.

Then he asked, "Mr. Qin, what do the symbols on it mean?"

"The form seems to be suitable for keeping accounts, but...you can't write?"

Wei Zheng really didn't have the nerve to tell the truth, these weird symbols written by Qin Yu looked like ghostly drawn symbols, which were really hard for people to understand.

Qin Yu: "..." This is a bit embarrassing.

"That's what, this is the text I brought from later generations, this is called Arabic numerals."

"Ah... Rab?" Wei Zheng looked confused, what kind of strange name is this?

Qin Yu explained: "Arabic numerals were invented by people from an overseas country called ancient India, and later spread to Europe by the Arabs, and then modernized by the Europeans, because of the spread of the Arabs, they became this kind of numerals. The key nodes that are finally used internationally, so people call them Arabic numerals."

"Oh!"

"So that's the case."

"It's just how to read the Arabic numerals?"

Although he knew it was a number, Wei Zheng still didn't know it.

"It's okay, I'll teach you."

Teach Wei Zheng, and he will be able to read the books more easily in the future.

"Thank you, Mr. Qin."

Hearing that Qin Yu was going to teach him, Wei Zheng's eyes narrowed with joy.

I said so much before, for this purpose, he needs Qin Yu to teach him to know this kind of numbers.

He's not stupid, but he can tell at a glance that what Qin Yu wrote on the form is relatively simple and clear, and he can intuitively see the various data on it at a glance.

The only thing that troubled him was not knowing the numbers above.

Now that Qin Yu said that he would teach him, he was naturally very happy.

"It's 1..."

"1..."

then.

Qin Yu transformed from a storyteller into an elementary school elementary school teacher gorgeously.

Teach Wei Zheng to recognize each character.

Fortunately, adults learn things much faster than children.

After several times, Wei Zheng learned Arabic numerals.

Then Qin Yu taught Wei Zheng to write.

It is not difficult to write numbers.

After Wei Zheng grasped it quickly, Qin Yu expanded it for him, the combinations of numbers within ten and twenty.

Wait until Wei Zheng has fully learned it and can use it.

Qin Yu took a pen and started writing on the side again.

"Mr. Qin, what is this writing?"

Wei Zheng leaned over curiously, and saw that Qin Yu had written a lot of numbers, but he didn't recognize the symbols in the middle.

Qin Yu didn't say anything, but wrote quickly. After the last word was written, he said to Wei Zheng: "Master Wei, I will teach you a set of punishment formulas now."

"What are multiplication formulas?"

Wei Zheng still displayed the spirit of not being ashamed to ask questions.

"The multiplication formula is a formula that allows you to calculate quickly. Multiplication is the multiplication of numbers."

Although Wei Zheng didn't understand, what Qin Yu brought out was definitely a good thing, so he quickly saluted Qin Yu. "Wei Zheng thanked Mr. Qin for imparting knowledge. From today, Mr. Qin is Wei Zheng's teacher."

"Teacher, please be respected by Wei Zheng."

Qin Yu quickly moved away, "What are you doing?"

I can't bear to worship at every turn, do you want to send him away?
