Then Ying Zheng took the magnifying glass and looked at the thin wire carefully.

When I saw this, I was shocked again.

The words engraved on it are indeed!

The four words "Make money from Daqin"!

Moreover, there are some strange lines behind, even circles.

"Make money in Daqin?"

Ying Zheng said strangely, "There are these words? But what is behind it? Could it be what mark?"

"Report to your Majesty, it's almost the same."

Feng Zheng smiled and said, "Actually, the latter are more like numbers than marks."

"number?"

【Yes, Arabic numerals…】

What?

Arabic numerals?

What is that?

After hearing Feng Zheng's words, Ying Zheng felt puzzled.

What are Arabic numerals?

"Report to Your Majesty, this is called Ah... No, this is called counting numbers."

"Perform numbers?"

Ying Zheng asked, “Is it specially used to carve money?”

"Your Majesty, this is not."

Feng Zheng said, "It is used to replace Qin Xiaozhuan, such as one, two, three, four, six, seven, eight, ninety, and the words are written in Qin Xiaozhuan, and if you use numbers, it is 1, 2, 3, 4, 5, 6

,7,8,9,10."

"Is this a replacement for these? What does it mean?"

"Report to your Majesty, it's good to write this word, but if you run fast calculations, it would be too complicated. Therefore, using some simple symbols instead can improve efficiency."

"But that's the case?"

Ying Zheng nodded after hearing this and understood Feng Zheng's meaning.

Use these to replace those complex words to improve the computing speed?

Very thoughtful.

"Hey, your last one is ten? Why are there two symbols?"

"Report to Your Majesty, this is actually one and one is zero."

Feng Zheng explained, "These two add up to one ten, and if there is one zero in the back, it is a hundred. If there is one more, it is a thousand. If there is one more, it is a thousand. If there is one more, it is ten thousand. If there is one more, it is a thousand. If there is one more, it is a thousand. If there is one more, it is a thousand. If there is one more, it is a thousand. If there is one thing behind, it means that it is a lot.

Ten times the original one.”

"That's true..."

After hearing Feng Zheng's words, Ying Zheng nodded, "Then do you teach those students like this in the school?"

"Yes, your majesty, that's exactly that."

Feng Zheng smiled and said, "I don't know how many times the efficiency has been improved by using these numbers to replace those Qin Xiaozhuan."

That's right, the operations of ancient China were superb or not, and that was indeed superb.

However, it has not been overpopular, because even before liberation, many ordinary people find it difficult to achieve slightly more complicated operations.

Why?

It is because Arabic numerals were not popular at that time. When people faced the cumbersome man numbers, one was because of the low cultural popularity rate, and the other was because of the particularly cumbersome operation, which also affected everyone's mathematical operation level.

Although there were many outstanding mathematicians in ancient China, this kind of academic cannot be studied and popularized in depth, and can only become a non-disciplined and strange science.

Whether it is academic or something, if it is particularly troublesome to use, it will be difficult to become popular and used.

If it is particularly simple to use, it will naturally be very popular.

"Ha, that's good, that's good."

Ying Zheng smiled and said, "Counting is also one of the six arts, but most of them are above the surface and have never been deeply involved. If you allow them to proficient in this art now, it would be a considerable contribution."

"Hey, thank you for your praise."

Feng Zheng smiled and said to himself, [Then of course I have to make their mathematics more advanced. After all, it’s business, how can it be possible to leave mathematics?

Apart from doing business, all other craftsmanship is simply not possible without mathematics.]

[Mathematics is one of the most basic subjects in the future. Even if you are not good at Chinese, you can just know how to speak and speak. If you don’t know how to do math at all, then you will really add a lot of trouble to yourself.]

Um?

After hearing Feng Zheng's words, Ying Zheng's heart suddenly moved.

So this type of numbers is so important in the future?

"The numbers behind the money made by Your Majesty, the Great Qin Dynasty, represent the time and batches of the money."

Feng Zheng said, "So every banknote can be traced. With this guarantee, it is naturally more difficult for others to falsify them at will. Of course, this is the insurance inside, because generally, banknotes are also

I won't tear it out casually."

"Ha, that's true."

Hearing Feng Zheng's words, Ying Zheng smiled and nodded.

If the banknote is torn to pieces in order to distinguish between true and false, then this banknote will basically be ruined.

However, this can be used as an extraordinary means to make judgments. If someone commits fraud, it can also be judged.

"Haha, your work is really good."

Ying Zheng smiled and then stuffed Feng Zheng's magnifying glass into his cuffs.

Clean and neat...

【Does me fuck? That's mine!】

Seeing this, Feng Zheng suddenly twitched slightly.

【Forget it, it’s just a mirror…】

Right...

Ying Zheng thought to himself, isn’t it just a mirror?

But this thing is really fun. Ying Zheng thought to himself that sometimes he has poor eyesight, and using this thing may be effective.

"Your Majesty actually has another point besides the above two points."

Feng Zheng pointed to a place in the coins and said, "Please touch this place."

Um?

Touch it?

What can you find?

After hearing this, Ying Zheng reached out and touched it with curiosity.

hiss?

Have bumps and patterns?

“This…has raised lines?”

Ying Zheng was curious and looked carefully, then touched it again. The painting of the banknote was indeed patterned!

"Hey, your majesty, that's exactly that."

Feng Zheng said, "Your Majesty, the patterns on the banknotes are not drawn, but printed. This is not a simple flat laying."

"Your, how did this be done?"

After hearing this, Ying Zheng asked curiously.
Chapter completed!
