Chapter seven hundred and sixty two histories that passed by
"First of all, since we are talking about currency, let us start from a simple place..."
Douglas's eyes did not stay long, looking around the spacious auditorium, and then continued.
"There is only one system of currency in the wizarding world. Although their names may be slightly different in various countries, their denominations and exchange rates are completely the same. In the UK, we usually call them gold galleons.
, Yin Xike, Copper Nat, you can touch the bottom of your chair now..."
After looking at the people who were bending down and groping in unison, Douglass said with a hint of cunning in his eyes.
"Of course, there is nothing down there. But don't worry, after this introduction meeting is over, everyone will receive a money bag, which contains the salary advanced to you by Hogwarts, in the form of magic currency. Now everyone
You just need to be a little familiar with and memorize the exchange rules. 29 copper nats are equivalent to 1 silver sicol, and 17 silver sicols are equivalent to 1 gold galleons. In other words, 493 copper nats are equivalent to 1 gold galleons. Isn’t that quite the same?
Simple and easy to remember?”
Following the middle-aged goblin's rapid-fire introduction, there was an extremely rare silence.
A strange expression appeared on some people's faces, like constipation, as if they wanted to complain about something but didn't know where to start. On the other hand, a very small number of scholars were stunned for a moment and then fell into deep thought.
"Don't you, um, I mean the wizarding world think this is a bit... um, inconvenient?"
Sitting on the seat to the left 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 consistent..."
These days, Chomochika has often heard his teacher complain about the huge gap in the field of mathematics in the wizarding world. If it weren't for Alexei's daughter who happened to be enrolled in school, he would have almost become the person to enlighten young children in mathematics.
.
It was really hard for him to imagine that a group of wizards who were not even proficient in arithmetic and equations would use such monetary rules.
"Sorry, I don't think there is anything wrong with this. This system has been used for thousands of years."
Douglas bowed politely, grinned, and said softly.
"Even if there are to be adjustments in the future, the adjustment can only be made starting from Yin Xi Ke at most, because when this currency system was first formulated, the magic world has already determined that as long as it is still Copper Nat, it must be
29."
"Why? Because of your mysterious magic?"
Qiaomochika shook his head in disbelief and asked unceremoniously.
Although he didn't know what deal the middle-aged goblin behind the scenes had made with the teacher, he still felt a sense of disharmony based on the mindless conversation just now and the minutiae of the past few days.
atmosphere.
If it involves magic, he really doesn't understand.
But if the other party takes the initiative to open up the "secret fighting field" to the digital aspect, then Qiaomochika does not think that he will be worse than these short goblins. The more the two sides talk, the more information they can obtain about the magical world.
many.
"It's not magic. Jomo."
However, before Douglas could speak, a long and leisurely voice suddenly came from Qiao Mochika's ear.
"Because...copper is 29, 2-8-18-1, it's such a wonderful number."
Arkhipovna from the Landau Institute lightly patted the "junior" on the shoulder and said in a complicated tone.
If Chomochka, as a pure mathematician, is not so sensitive to the numbers and words in the goblin's mouth, then researchers in the field of physics or chemistry, if they hear the other party emphasize the numbers twice in succession, and the words in the sentence,
It would be too embarrassing for those firm words to fail to reflect what the other party is saying.
"You just said that your magical world has been using this monetary system for nearly a thousand years?"
Arkhipovna turned her head and took a deep look at the middle-aged goblin, "Then why is the silver coin not 47, but 17 equivalent to 1 gold galleons? This should be more in line with the conversion between this set of currencies.
Rules, right?”
"The first reason is because neither gold galleons nor silver silico are gold and silver in the true sense. Reason two..."
The smile on Douglas's lips gradually widened, and his slender fingers lightly drew in front of him.
Immediately afterwards, dozens of bright coins collided with each other, jumped out of its pocket empty-handedly, and floated precariously in front of everyone, and the one at the front happened to be a row of silver coins.
Can.
"As this gentleman reminded us, it can be a little more convenient for subsequent calculations."
…
"Let's assume there are sixteen Silver Sikos here, and suppose you still have one Silver Siko in your hand..."
At the same time, in Hogwarts Castle, in the math and physics classroom.
Alexey stood at the edge of the podium, looking at the red-haired boy in front of him with a kind expression, and patiently guided him. qq
"Then I give them to you together, then Mr. Weasley, you will end up with..."
"One, one gold Galleons?"
Ron Weasley hesitated for a moment and answered tremblingly.
"Well, that's indeed a good answer, if you're more used to thinking this way."
Alexei looked around at the faces in the classroom and spoke slowly and thoughtfully.
"Then let me change the question a little bit now. Suppose there are only ten Silver Sickles here, and you have seven Silver Sickles in your hand. If you add them all together... is it still one Gold Galleons?"
Ron nodded nervously, feeling a little more confident.
It might be a little better if he said it was just an ordinary question and answer, but the most important thing is that in all the above conversations, any vocabulary involving numbers, they all used the French number expressions they had just learned.
In fact, strictly speaking, they are only halfway through their first class.
Alexey even suspected that perhaps by the end of this semester, the little wizards in this class would be able to complete some basic daily communication in pure French and do some simple reading in pure French.
However, compared to Alexei's surprise, Elena, as the course organizer, was not much surprised.
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 from the Romance language family in which French is located during the development process, so it is not too difficult to learn.
Especially when this "foreign language course" appears in the magical world, it is a bit easier.
You must know that the Romance language family originally evolved from "Vulgar Latin", and most of the magic spells in today's magic world are either based on "Latin" or "Ancient Fusac".
For Elena and others who have studied at Hogwarts for more than a year, it is naturally much easier than those children from the non-magical world.
At the same time, at the podium not far away, the conversation had almost come to an end.
Alexei picked up a pile of "teaching tools" provided by Elena and placed them in Ron's hands one by one.
"Very good, but now you actually have seventeen silver coins in your hand, not one gold coin. So if you use a French description to express it, then your answer just now should be?"
"Ten plus seven (dix-color pt) silver coins." Ron swallowed and replied subconsciously.
"That's absolutely correct. Isn't it very simple? By analogy, according to the actual situation in the magic world, if you want to express to others that the price of an item is eighteen silver coins, then you have more than one way to express it.
It’s a formality, right?”
Alexei nodded with satisfaction, turned around and started writing quickly on the blackboard behind him.
"Ten plus eight (dix-huit) silver sikols, or, one (un) gold galleons and one (un) silver sikore."
After learning about the currency system in the magical world from Elena Kaslana, and confirming her thoughts in class, Alexey decided to respect the "eldest lady"'s suggestion and slightly change the teaching
Way.
After all, the main purpose of his class is to train mathematical abilities and mathematical thinking, and it is not a real French class.
Therefore, if there is a "arithmetic expression" method 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 these years of scientific research work, he has also begun to
I realize that most of today's languages and traditional expressions are not so easy to use in aspects that are more numerically intensive.
I have to admit that compared to non-magical children, the little wizards' reaction speed in numbers and their ability to learn and imitate new languages far exceeded Alexei's expectations. This may be the so-called talent.
Starting point problem.
On the other hand, there are some subtle differences between children from wizarding families and children from non-wizarding families.
When faced with abstract numerical operations, children from wizarding families are indeed much more confused than children from non-magical families, but when this thing is related to the currency in their daily lives, they show better performance.
Another talent that surprised him extremely was an incomprehensible arithmetic sensitivity for some weird base calculations.
And this 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 wrote quickly on the blackboard as he spoke.
"Now, let's use the pronunciations we just learned, corresponding to 0-9, and the characters α, β, γ, δ, ε, ζ, η, and put them together to express, then if it is 31 pieces of silver
