Number theory, or mathematical theory, is a name that only appeared in the twentieth century.

Prior to this, it was customary to refer to this branch of pure mathematics that specialized in integers (defining integers) as "arithmetic" because of its fundamental position in mathematical principles, and it was often referred to as the "queen of mathematics".

In fact, even in the second half of the twentieth century, the study of "arithmetic" in mathematical theory played a very important role, mainly due to the influence of the French mathematical community, the most powerful and prosperous mathematical kingdom in the field of modern mathematical theory.

This kind of mathematical strength is not only reflected in the number of mathematical geniuses, but also comes from the daily foundation and atmosphere.

Compared with other countries in the world, the French language does not use decimal logic when expressing numbers, and the basic counting in French uses the base 20 model, for example, the expression of 99 is 4*20+10+9, and after the spread of mobile phones, this has become a nightmare for all foreign tourists who are looking for a romantic getaway in France.

In France, the French do not read phone numbers as they do in other countries.

For example, in 65978376, instead of pronouncing 6-5-9-7-8-3-7-6, the French pronounce 65-97-83-80 in two pairs, which sounds like 60+5, 4x20+10+9, 4x20+3, 60+16.

In addition, if we talk about the difficulty of the exam-oriented education system in the field of mathematics alone, China's college entrance examination can only rank second.

As the most difficult and rigorous test-oriented education system in the world, French students who want to enter university must work very hard in the two (or three) years of high school to learn calculus and linear algebra skills to cope with the world's most difficult college entrance examination.

If it is converted into Chinese mathematics textbooks, then it is not a simple third year of high school, but a second year.

However, from this year onwards, secondary school mathematics in France is no longer the only "most fantastic" test-oriented education.

At Hogwarts Castle in the Scottish Highlands, the same is being seen in wizards' classrooms.

"Professor Alexey, I'm sorry, I have a question......"

Elena swept over the young wizards around her, and before the confusion on their faces could resurface, she raised her hand.

"Why do we need to learn French, if it's just four arithmetic, we also learn a little bit about simple addition, subtraction, multiplication and division in astronomy class, I see calculus in the textbook, but I've heard that England is the origin of calculus, right?"

"Oh, yes, that's a good question indeed—it seems that Miss Kaslana has prepared very well. ”

Alexei raised his eyebrows, glanced at the lesson plan on the table, and replied quickly.

"When you have studied mathematics for a certain period of time, and slowly follow the long river of mathematical history, to about the sixteenth or seventeenth century, you will find that in that era of geniuses, France is almost modern mathematics. ”

"Isaac Newton was indeed a great scholar, he contributed calculus, but he also blocked the development of science in England for nearly a hundred years, and after him, Vedda, Mason, Descartes, Fermat, Pascal, d'Alembert, Lagrange, Poisson, Fourier, Laplace, Cauchy...... These names, which still sound unfamiliar now, are almost the most famous scholars in the field of mathematical theory for nearly a hundred years to come, and they are all French. ”

Alexei looked away from the lesson plan, but the words in his mouth became more and more fluid, and his face was full of emotion.

"In any field, if you want to master the most core and complete knowledge, then learning in the native language of the knowledge discoverer is undoubtedly the most effective. This is also why the wizards of the British wizarding world are inherently more powerful than foreign wizards...... Spellbooks, potions, these are all written in English. ”

"Not to mention ......"

The middle-aged man suddenly winked at the little wizards.

"French, one of the most romantic languages in the world. I heard Professor Dumbledore say that next year Hogwarts will start an inter-school exchange with a certain school of witchcraft and wizardry in France, whether it is applying for an exchange student, or making friends with gentlemen and ladies from French schools of witchcraft and wizardry, and being fluent in French, this is one of the essential prerequisites. ”

"The school of magic in France?!really?!Is it true that the professor is talking about Beauxbatons School of Witchcraft and Wizardry?!"

Elena's eyes widened in surprise and she said quickly.

Behind her, the young wizards in the classroom began to talk about each other, and Draco Malfoy mysteriously introduced the romantic school of magic and magic full of "handsome guys and beauties" to the young wizards around her.

As for the source of information, it naturally comes from his father, who knows everything about "Hogwarts School Board Member".

"Oh, I can't tell you the details yet......"

Alexei touched his nose in embarrassment, and gently sorted out the finished speech in front of him.

In Elena's satisfied eyes, Alexei mysteriously added one last sentence.

"But I can swear it's definitely a big project that will be finalized in the next year or two, and you should be notified when the Ministry of Magic and Professor Dumbledore feel the time is right. Now let's return our attention to the lesson......"

"Big project, is it ...... Oh, I see—"

Elena nodded obediently, sat down, and took the initiative to open the textbook and prepare to start listening.

With the girl's movements, the discussion in the classroom gradually became quieter, and the students also suppressed the curiosity and confusion that were constantly surging in their hearts, cheered up, and looked at Mr. Alexey in front of the classroom with anticipation.

From any point of view, learning a romantic language in a country next to England sounds a lot more fun than boring numerical calculations and formulas, at least for now, as the little wizards think.

Not to mention, just now the professor seems to have revealed some amazing information.

With the babbling of the little wizards in French, a wonderful door to mathematics opened.

......

At the same time, it was in an empty classroom next to the mathematics and science classroom.

“...... It seems that the first lesson went quite smoothly and we shouldn't need to save the day. ”

Dumbledore breathed a sigh of relief, turned his head to look at Professor "Apocalis" sitting next to him, and on the table in front of him was an identical math textbook, and said softly with a somewhat forced smile in his tone.

"Speaking of which, Gail, your terrible French should indeed be practiced well, and it can be regarded as making up for your shortcomings. ”

"If it weren't for that bet, I wouldn't-"

Hearing Dumbledore's quip, the corners of Grindelwald's eyes couldn't help but twitch again, and he looked at the stack of "Hogwarts Year 1-7" math textbooks on the long table in front of him, and instantly felt a little more headache in his head.

As punishment for giving up the "SSS" commission to write about Muggle maniacs, he had to fulfill an Elena request.

What the original Dark Lord didn't expect was that the little witch put forward a condition - let him follow the little ones at Hogwarts to Math class, and complete all the lessons and homework in grades 1-7!

"I hate Paris, I hate French-"

Grindelwald shook his head and exhaled deeply.

He had known that such a thing would happen, and he should have been ruthless when he held a rally in Paris, and burned down the city full of evil numbers and devilish knowledge in one fell swoop, instead of making up for it here.

"You're so spoiled Elena, Gail...... I thought you would refuse her request. ”

Dumbledore's blue eyes flickered and he whispered meaningfully.

"I didn't expect that you were the one in all of Hogwarts who was the most supportive of her educational reforms, and even took the initiative to endorse that child's ideas, which surprised me a little - if I'm not mistaken, you'd probably be teaching yourself Muggles, right?" What the hell are you thinking, Gail?"

"It's just to complete the little devil's mission, don't think too much, Albus. ”

Grindelwald replied with an unchanged face, calmly looking at the stack of materials stacked on the long table next to him.

"Aren't you also learning these troublesome things, the headmaster of Hogwarts School of Witchcraft and Wizardry, the greatest wizard in the wizarding world today, will be reduced to the point where you need to sneak over to skip the students' lessons-"

"Times have changed, old man, and I'm not an outspoken guy like you. ”

Dumbledore shook his head with emotion, his slender fingers tapping lightly on the stack of textbooks in front of him.

Centuries ago, wizards wielded wands and magic, but they still had no trouble understanding what Muggles' knights' armor and two-handed swords were, as well as what Muggles' astrological charts depicted.

However, in this day and age, wizards still use traditional wands, with owls acting as messengers to travel between fireplaces, but they are completely unable to understand what Muggle telephones and computers are, and most of the functions of the "Huberion" flying over Hogwarts are extremely foreign to Dumbledore.

Undoubtedly, enrolling students from the non-magical world allows wizards to learn how to use these industrial products.

But if this is all there is to it, wizards living in the wizarding world will never be able to understand the principles and knowledge behind those little things, just as Muggles will never be able to understand the true meaning of the Patronus Charm.

"As a wizard, it's really not difficult to master simple math calculations and language skills......

Dumbledore listened to the sound of reading from the classroom next door, a smile on his old face.

"However, if the wizarding world wants to truly understand and understand the foundations of the power of 'science', then there is so much we need to catch up with and make up for - it is difficult for our generation to change, but these children still have a chance to catch the train to the new world, even if it is a little harder, it is better than being abandoned by the world in the future......"

"That's what it is...... The reason for the existence of Hogwarts School of Witchcraft and Wizardry. ”
