Today's girls, all they think about are unicorns......

In the long run, it is not a good sign, and as a righteous little angel, you should find a way to ring the alarm bell.

Elena glanced meaningfully at the Hogwarts girls surrounding Luna, and an unfathomable and mysterious smile appeared on her face.

Why do these innocent children at Hogwarts always fail to understand this obvious truth?

Of course, popularizing the knowledge of magical beasts is one thing, and the most important purpose is to let those bewitching sluts who covet and approach her wings know that casual pick-up and slapping and feeding may trigger strange branch endings.

As for the lucky little witch who will have the next "close contact", it is natural to randomly select a few from the senior sisters who have been chatting and feeding around Luna, Hannah, and Hermione all day long, and laughing very happily.

After silently taking out her notebook and arranging the few little witches who were asking when there would be a chance to photograph Fantastic Beasts next time, Elena turned her gaze to the faculty chair located in the innermost part of the auditorium.

Although the past few days have not been particularly pleasant and peaceful for Professor McGonagall and Professor Flitwick, they can't help but smile with satisfaction and pride when they see the article that they have revised and supervised is printed.

And Professor Sprout and Professor Snape beside the two of them also had a thoughtful look on their faces.

After reaching the level of official professor at Hogwarts, what you need to pursue is not only the improvement of personal ability, but also the training of students and the contribution to the professional education of the subject.

There is no doubt that compared to the scattered, fragmented and large-scale scattered net of casual submissions in the past.

The academic section that has now been created in New Singing and Singing is a perfect place for professors to publish their research and guide students to publish excellent academic articles in a unified manner - not to mention, it is also a window to showcase the excellence of Hogwarts School of Witchcraft and Wizardry to the wizarding world.

As it turns out, the students at Hogwarts are not unintelligent, and their overall academic standards have not slipped in the slightest.

It's just that there is a lack of clear goals and systematic guidance and planning before this, so it will not be so eye-catching, so that in the past few years, there have been voices in the wizarding world questioning the teaching standard of Hogwarts.

And now that Percy and others have published magical research papers, although they still seem a little immature, they are enough to respond to all the doubts from the outside world, and many professors have begun to think about what topics should be assigned to students in the next issue.

Not only the writing of papers, but also the presidents and deans of professors such as Dumbledore, McGonagall, and Snape have more and more comprehensive considerations than mere "subject leaders".

For example......

If you want to select the male and female prefects of each house, you should at least publish a basic magical research article in the "Into the Magic" section.

If you want to select the male and female student presidents of Hogwarts, you need to have published at least three magical papers equal to or higher than "Into the Magic", and have received at least one headline position on the board.

If you want to get an excellent graduate qualification after graduation and get a letter of introduction from the professors of the school, you also need to ......

All in all, after such a successful test of the waters, many Hogwarts professors have become active, and they intend to take this opportunity to continue and spread this excellent way of learning and their own educational achievements.

As for the professors' new ideas, the little wizards don't have much interest for the time being.

To be precise, even if they knew, except for a few students who were obsessed with prefects and student council presidents, the vast majority of young wizards would not feel that these things had much to do with themselves.

After breakfast, the students began to follow the secret passages introduced by the Weasley twins, and gradually explored around Hogwarts Castle, including the forbidden areas that Filch had previously suggested, and there were also many daring little wizards wandering around there.

But fortunately, because of the right of "public execution" in Filch's hands, most of the young wizards only looked outside, and did not really dare to take the initiative to enter - Argus Filch, as the castle keeper, could intuitively feel that since the release of "New Singing and Singing", the young wizards have been much more disciplined than before.

What makes Elena even more satisfying is that since the afternoon, people have begun to notice the "easter egg board" hidden in "New Singing and Singing" - an introduction to the basics of elementary mathematics and interesting trivia quizzes.

The familiar and simple explanation of the "chicken and rabbit in the same cage" problem instantly reminds people of the problems of this year's Eagle Ring.

Since the beginning of the semester, the Bronze Eagle Ring's varied and quirky "cage" title has been a mountain that has kept Ravenclaw students back to their dorms sleeping, and many poor eaglets have slept in the hallways twice as long as they have slept in their beds.

As a house known for its wisdom in Hogwarts, all Ravenclaw students know that the title of the Eagle Ring is actually an infinite variation of an arithmetic problem, because Hogwarts still has two courses: arithmetic divination and astronomy.

However, knowing what it is and what category it belongs to does not mean that you know the solution behind each question.

In particular, Elena's in-depth and step-by-step mathematical foundation was something that had never been done before in the wizarding world, and it was even rare in European primary and secondary education in this era.

Considering that many children from wizarding families in the wizarding world do not have primary education, not to mention some more skillful ways to solve problems, there may be some problems with some basic four operations.

Therefore, Elena spent half a page in this issue of "New Singing and Singing - Mathematics Section" and moved a whole ninety-nine multiplication table to it, as for the interesting trivia link, it is naturally the favorite problem of chickens and rabbits in the same cage.

For a while, this boring digital table that seemed dizzying to other houses and wizards became the main concern of every Ravenclaw student—unicorns, secret passages, and food were all secondary to the temptation to go home, and they were almost forgetting what the soft dorm bed looked like.

The Ravenclaw table that night was undoubtedly the happiest place in all of Hogwarts, with a smile of pure pride on each of the young wizards' faces, and everyone enjoying their meal in a relaxed mood without having to think about how to get in tonight.

In addition, the ninety-nine multiplication table, which is full of mysterious beauty and mathematical rhyme, has also become the most discussed thing among Ravenclaw students—almost all of them bow their heads from time to time and silently recite a few words, carefully feeling the essential leap in calculation speed brought by the optimization of the algorithm.

But this time, it made the other three colleges a little baffled.

Because of the difference between interest and house atmosphere, few children from other houses than Ravenclaw College could understand the joy of the heavenly maze of numbers.

You know, before this, although the little ones of Ravenclaw would come up with some difficult and philosophical words from time to time, at least they still sounded "human words" that could be understood, and in less than half a day, the entire academy had become a sea of mathematical enlightenment.

If you get a little closer, you can hear a little wizard whispering a sentence like a magic spell from time to time.

"One by one, one by two, one by two, two by two......"

"Two or three get six, two four get eight ......"

It's not that Elena did any magic in the magazine.

The main reason is that the calculation method used in the wizarding world, or in Europe, is too weird before this - normal addition and subtraction is fine, but when it comes to multiplication and division, the whole painting style begins to become cheerful.

Whether it is the decimal multiplication formula table from the United Kingdom, or the decimal multiplication calculation method introduced from the East, it is usually not exposed until around the time of the college entrance examination (A-level), and before that, there is a level called the preliminary examination (GCSE).

However, even for the first exam, in the non-magical world, you need to wait until you are sixteen years old.

For the children of the wizarding world, this time is actually equivalent to the age of a sixth-year Hogwarts student, and it is conceivable that even if the progress of mathematics from the non-wizarding world is synchronized, it will not be very advanced.

In fact, if Elena remembers correctly, even in the preliminary stage, British students faced with "complex multiplication", that is, multiplication of more than two digits, in addition to using calculators (obviously, Hogwarts does not support this form), they still rely more on the legendary method of drawing lines and counting points.

What is the method of drawing a line and counting points?

For example, if it is roughly 12X11, then the British children will draw a vertical line for 10 and then two vertical lines for 2, and "12" will be represented by this: (Picture .jpg)

Then draw two horizontal lines to indicate "11" :(picture 2.jpg)

Then start to find the intersection of these lines, starting from the bottom right corner and counting the points, and the intersection points from the bottom right corner to the bottom left corner, in the order of one, ten, hundred, thousand, and ten thousand: (picture 3.jpg)

When counting, if there is more than 10, just go one place and mark it next to it.

So, 12X11=132. (Picture 4.jpg)

In fact, this algorithm, called "linear algebra (pseudo)", although it seems a bit fun at first glance, but for British children who hate rote memorization, they only need to be able to count the dots, and they don't have to memorize any complicated multiplication formulas.

In fact, in the original book, when Harry, Ron and others were coping with astronomy class homework and calculating the trajectory of the stars, the horizontal and vertical lines on the sheepskin spread out on the table were making multiplication drafts.

However, the only small problem with this method is that as the number expands or the second half of the singular number appears frequently, just counting the dots can give people a feeling of wanting to die - for example, when 998 times 777 appears......

Perhaps in the eyes of the Gryffindor lion cubs, happily drawing lines and counting dots is still the most comfortable way to calculate.

However, for Ravenclaw students who have a higher pursuit of wisdom and skill, this kind of knowledge of mastering the key to algorithms, being able to solve more tedious problems, and find the right answers more quickly is undoubtedly the most fascinating.

At least the most obvious change is that from now on, whether it's arithmetic divination or astronomy, they Ravenclaw will leave the students of the other three houses far behind—both in terms of the speed of calculations and the accuracy of calculations.

In this way, in a joyful atmosphere, the young wizards of Ravenclaw whispered and left the Great Hall of Hogwarts with brisk steps while silently reciting the "Ninety-Nine Multiplication Table", and everyone's eyes flashed with reverie for a better future.

Very well, it seems that the Ravenclaw eaglets have already tasted a little sweetness.

Elena glanced at the Ravenclaw students who were obsessed with the fascination of mathematics, and the corners of her mouth rose slightly with pleasure.

In the following time, she will also secretly ask the house-elves to go to Ravenclaw College next to the Eagle Ring to update some problem banks, but the overall difficulty is always to be able to be solved by the ninety-nine multiplication table, some more basic math quizzes.

Just like fishing at the lake, if it's too rough at first, it's easy to scare these timid kids away.

Only a little bit of bait first, so that they all taste some sweetness, and are full of confidence in themselves, is the time to really open the door to the temple of mathematics for them.

Of course, for Elena, these are just issues that need to be slowly polished and thought about in the subsequent fermentation of the magazine, and she is not in a hurry to arrange them all in a short time.

After a busy week, she just wanted to eat and drink well, and be a little salted fish witch who had nothing to do.

That evening, a small celebration was held in the Hogwarts kitchens.

In addition to Elena and her little wings, the Weasley boys, the top students from the various houses, and even Argus Filch, the castle keeper, were invited.

While celebrating the successful publication of "New Singing and Contrarian", Elena also paid this week's remuneration on the spot.

Accompanied by the aroma of roasted meat, the aroma of butterbeer, and the sound of the jingling of the golden gallons, even the usually stern Argus Filch smiled a rare smile.

After so many years of working as an administrator at Hogwarts School of Witchcraft and Wizardry, he had never been so noticed by the wizarding world.

What's more, Elena Kaslana is so generous that with so much extra income, he can finally consider buying Mrs. Loris a whole new set of cat toys, litter boxes, and cat kennels.

Of course, there is another reason that the skewers grilled by Elena are so fragrant - most people will be in a good mood in the face of delicious food.

Argus Filch as an adult, not to mention the young wizards who had not yet graduated, everyone was excited, even the usually steady Percy Weasley couldn't help but show off his singing voice in the kitchen space, and the brothers George and Fred joined hands to do a tap dance......

Faced with the rare lively and cheerful scene in the kitchen, Elena, who was responsible for the barbecue, squinted her eyes quite happily, and hummed the melody of a song that no one had ever heard before.

Not far away, Hermione, guided by Hannah, should be playing awkwardly in circles with Argus Filch's scattered beats with both hands, avoiding bumping into the Weasley twins next to her, while carefully dancing the newly learned jazz dance with a nervous face.

In the bustling kitchen, a white light flashes from time to time, and it is Luna holding her beloved camera to capture the precious moments she thinks are worth keeping......

In the laughter and aroma of barbecue, the first day of the release of "New Singing and Singing" drew a perfect end.
