Chapter 760 2 histories that passed by

“First of all, since we are talking about currency, let’s start with a simple place…”

Douglas didn’t stay for long, looked around the spacious auditorium, and then went on.

“There is only one system of currencies in the magical world. Although they may be called slightly different in various countries, their face value and exchange rate are completely interlinked. In the UK, we usually call them golden gallons. , Yinxi Ke, Tong Nath-well, you can touch the underside of your chair now…”

Looking at the people who stooped down and groped, Douglas said quickly.

“Of course, there is nothing below. But don’t worry. After this briefing is over, everyone will receive a purse containing the salary advanced by Hogwarts, in the form of magic currency. Now everyone Just a little familiarity and memorization of the exchange rules is good. 29 copper nits are equivalent to 1 silver xico, and 17 silver nits are equated to 1 gold gallon. That is to say, 493 copper nits are equivalent to 1 gold gallon. Simple and easy to remember?”

After the introduction of the middle-aged goblin, there was an extremely rare silence.

Some people have a strange look like constipation on their faces, as if they want to complain about something, but they don’t know where to start. On the other hand, a very small number of scholars are first stunned and then plunged into contemplation.

“You guys, uh, I mean, don’t the magical world find this a bit… uh, inconvenient?”

In the seat on the left hand side of Vinogradov, a slightly younger middle-aged man raised his eyebrows.

“I mean, at least you can consider making the exchange of copper coins and silver coins the same…”

These days, Jomochka has listened to his teacher complaining about the huge gap in the field of mathematics in the magical world. If it weren’t for Alexey’s daughter who happened to be in school, he would almost become the person who enlightened children in mathematics. .

It is really hard for him to imagine that a group of wizards who are not proficient in the four arithmetic operations and equations would use such monetary rules.

“Sorry, I don’t think there is any problem with this. This system has been used for thousands of years.”

Douglas yawned politely, grinned, and said softly.

“Even if adjustments are required in the future, at most, adjustments can only be made from Yinxi Ke, because when the currency system was first formulated, the magic world had already determined one point. As long as it is still copper nat, it must be 29.”

“Why? Because of your mysterious magical reasons?”

Joe Mochika shook his head with a smile, and asked unceremoniously.

Although it is not clear what deal the master behind the middle-aged fairy made with the teacher, he also felt a little bit of disharmony just based on the thoughtless conversation just now and the details of these days. atmosphere.

If it was related to magic, he really didn’t understand.

But if the other party took the initiative to open up the “secret matchmaking realm” to the digital aspect, then Joe Mochika did not think that he would be inferior to these short fairies. The more the two sides talked, the more information they could obtain about the magic world. many.

“Not magic. Jomo.”

However, before Douglas could speak, a leisurely voice suddenly came from Joe Mochika’s ear.

“Because… the copper is 29-2-8-18-1, it’s a wonderful number.”

Arkhipovna from the Landau Institute lightly patted the shoulder of the “little brother” and said in a complex tone.

If, as a pure mathematician, Joe Mochika is not so sensitive to the numbers and vocabulary in the mouth of the fairy, then whether it is a researcher in the field of physics or chemistry, if you hear the other party emphasize the number twice in a row, and the sentence Those firm words can’t reflect what the other party is saying, which would be too embarrassing.

“You said just now that your magical world has used this currency system for nearly a thousand years?”

Arkhipovna turned her head and took a deep look at the middle-aged fairy, “Then why is Silver West not 47, but 17 converted to 1 gold gallon, so it should be more in line with the conversion between this set of currencies. Rules?”

“Reason one, because Jin Jialong and Yinxi Ke are not gold and silver in the true sense. Reason two…”

The smile at the corner of Douglas’s mouth gradually pulled away, and his slender finger swiped in front of him.

Immediately afterwards, dozens of brightly colored coins collided with each other, vying to jump out of its pockets first, and swayed in front of everyone, and at the front was a row of silver west. can.

“As this gentleman reminded us, it can be slightly more convenient for subsequent calculations—”

…

“Suppose there are sixteen silver sikes here, suppose you still have one silver sike…”

At the same time, Hogwarts Castle, in the math and science classroom.

Alexei stood on the edge of the podium, looked at the red-haired boy in front of him kindly, and guided patiently.

“Then I will give you a word of them together, then Mr. Weasley, you will eventually get…”

“A Jin Jialong?”

Ron Weasley hesitated and replied tremblingly.

“Well, this is indeed a good answer, if you are more used to this way of thinking.”

Alexei looked around the faces in the classroom and said slowly and thoughtfully.

“Then I will change the question a little bit now. Assuming there are only ten silver sikes here, and you have seven silver sikes in your hand, then if you put them together… is it still a golden Jialong?”

Ron nodded nervously, a little more confident in his heart.

If it is just a general question and answer, he might be a little better, but the most important thing is that in all the above dialogues, all vocabulary involving numbers, they use all the French number expressions they just learned.

In fact, strictly speaking, their first class has just been halfway through.

Alexei even suspects that perhaps by the end of this semester, the little wizards in this class can almost complete some basic daily pure French communication and read some simple pure French content.

However, compared with the surprise in Alexei’s heart, Elena, as the course organizer, did not have many surprises.

Unlike Russian, which belongs to the Slavic language family, although modern English belongs to the Germanic language family, it has incorporated too many vocabulary and reading and writing methods of the Romance language family where French is in the process of development, so it is not too difficult to learn.

Especially when this “foreign language class” appeared in the magic world, it was a bit simpler.

You should know that the Romance language family originally evolved from “popular Latin”, and most of the spells in the magical world today are either “Latin” or “Ancient Fusac” as a reference. For Elena and others, who have studied at Hogwarts for more than a year, it is naturally much easier than those in the non-magical world.

At the same time, on the edge of the podium not far away, the dialogue almost reached the end.

Alexei picked up a stack of “teaching props” provided by Elena and placed them in Ron’s hands in turn.

“Very good, but now you actually have seventeen (seventeen) silver coins, not a gold coin, so if you use the French description to express it, then your answer just now should be?”

“Ten plus seven (dix-sept) silver cikes.” Ron swallowed and replied subconsciously.

“Exactly correct, is this very simple? By analogy, according to the actual situation of the magic world, if you want to express to others that the price of a commodity is 18 silver, then you have more than one expression It’s a formality, right?”

Alexey nodded in satisfaction, turned around and started writing quickly on the blackboard behind him.

“Ten plus eight (dix-huit) silver sikes, or one (un) gold plus one (un) silver sikes.”

Since I learned about the currency system in the magic world from Elena Kaslana, and confirmed what I thought in class, Alexey decided to respect the suggestion of “Miss” and change the teaching slightly. the way.

After all, the main purpose of his class is to train mathematical ability and mathematical thinking, not a real French class.

Therefore, if there is a “arithmetic expression” in the magical world that is more suitable for students to understand, then Alexei is naturally willing to take the initiative to try it, especially with the scientific research work in these years, he also started I noticed that most of today’s languages ​​and traditional expressions are starting to be less useful in some aspects that are more value-intensive.

I have to admit that compared to children in the non-magical world, the speed of reaction of little wizards in terms of numbers and the ability to learn and imitate new languages ​​far exceeds Alexei’s expectations. This may be the so-called talent. The starting point.

On the other hand, ~www.readmtl.com~ children from wizard families and children from non-witch families also have some subtle differences.

When faced with abstract numerical calculations, those children from wizarding families are indeed much more confused than those from non-magical families, but when this thing is connected to the currency in their daily lives, they show Another talent that surprised him, an incomprehensible arithmetic sensitivity to some weird base calculations.

And this also means that they may really have what Elena calls the potential to change the world.

Of course, before that…

Alexei picked up the chalk, and while talking, he wrote quickly on the blackboard.

“Now, we use the pronunciations we just learned, corresponding to 0-9, and the characters α, β, γ, δ, ε, ζ, η, put them together to express, then if it is 31 silver Xi Ke, then the corresponding is 1ε…”
