Hogwarts on the Tip of the Tongue

Now girls, all they think about is the unicorn ...

If this goes on, it is not a good sign. As a little angel of justice, I should find a way to sound the alarm.

Elena glanced meaningfully at the Hogwarts girls around Luna. A mysterious smile appeared on her face. The object of this intimate contact was the little unicorn. Yeah.

Why do these naive children at Hogwarts always wonder about this obvious truth?

Of course, popularizing the knowledge of magical animals is one aspect. The most important purpose is to let those coveted and fairies who are close to her wings know through this comparison that casual chatting and slapping and feeding may trigger strange branch endings.

As for the lucky little witch in the next "intimate contact", it is natural that the senior school sisters who have been chatting and feeding around Luna, Hannah and Hermione all day long are very happy, and they are randomly selected. Too.

After silently taking out the small book and arranging the little witches who were inquiring about the next time they still had the opportunity to photograph magical animals, Elena turned her attention to the faculty seat at the innermost position of the auditorium.

Although for Professor McGonagall and Professor Flitwick, the past few days have not been particularly pleasant and calm, but when they saw the article after their revised guidance printed, the two still couldn't help but show a smile of gratification and pride. .

The faces of Professor Sprout and Professor Snape beside them also showed a thoughtful look on their faces.

After reaching the level of Hogwarts formal professors, what we need to pursue is not only the improvement of personal abilities, but also the cultivation of students and the contribution to professional education in this discipline.

There is no doubt that compared with the past scattered, unsystematic and scaled cast-in-the-art submission.

Today, the academic section developed on "New Singing Opposition" is a very suitable place for professors to publish their own research results and guide students to publish outstanding academic articles in a unified manner-not to mention, through this window, you can also send magic The world showcases the outstanding teaching achievements of Hogwarts School of Witchcraft and Wizardry.

Facts have proved that Hogwarts students are not unwise, and the overall academic level has not declined at all.

Only before this lack of clear goals and systematic guidance planning, so it seems that it is not so dazzling, so that in the past few years, the magic world has always voiced questions about Hogwarts teaching level.

But now the magic research papers published by Percy and others, although they still seem to be a bit immature, are also enough to respond to all questions from the outside world. Many professors have begun to think about what topics should be assigned to students in the next issue. wrote.

More than just writing papers, principals such as Professor Dumbledore, Professor McGonagall, and Professor Snape, and dean-level faculty and staff have more considerations than simple "discipline leaders" More and more comprehensive.

For example ...

If you want to choose the male and female class leaders of each college, you must at least publish a basic magic research article in the "Into the Magic" section.

If you want to select Hogwarts male and female student chairpersons, you must at least publish more than three magical papers at the same level or higher than "Walk into Magic", and at least get the headline push position of the plate.

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

All in all, after such a successful water test, many professors at Hogwarts have revived their thoughts, intending to use this opportunity to continue and spread this excellent method of academic study and their own educational achievements .

Regarding the new ideas of the professors, the little wizards are not yet very interested.

To be precise, even if you know that, except for a few students who are obsessed with the class leader and the chairman of the student union, most of the little wizards will not feel that these things have much to do with themselves.

After breakfast, the students gradually began to explore the Hogwarts Castle according to the secrets introduced by the Weasley twins, including the prohibited areas Filch had suggested before, and there were many bold little wizards there. Wandering nearby.

But fortunately, deterring the right of "public execution" held by Filch, most of the little wizards just looked outside and did not really dare to take the initiative-Argus as the castle administrator ? Felch can intuitively feel that since the release of "New Singing Contrast", the little wizards have been more organized than before.

What is more satisfying for Elena is that since the afternoon, some people have begun to notice her "Egg Plate" hidden in "New Singing Contrast"-an introduction to elementary mathematics and interesting little knowledge quiz.

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

Since the beginning of this semester, the variable and quirky “cage” topic of the bronze eagle ring has been a mountain that has blocked Ravenclaw students from sleeping in their dorms, and many poor eagles have even slept in the corridors. More than double the time spent sleeping in bed.

As a well-known academy in Hogwarts, all Ravenclaw students know that the question of the eagle ring is actually an infinite variant of an arithmetic problem, because Hogwarts still has arithmetic divination and astronomy courses. Course.

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

In particular, Elena is so simple and simple, step by step to strengthen the foundation of mathematics, the magic world can be said to have never been before, and even in this era of European primary and secondary education is rare.

Considering that many children of wizarding families in the magic world do not have a link to elementary school education, let alone some problem-solving methods that require more skills, there may be some problems with some basic four arithmetic operations.

Therefore, in this issue of "New Singing Contrary-Mathematics", Elena specially spent half of the space and moved a full ninety-nine multiplication table to it. As for the interesting little knowledge link, it is naturally a favorite Cage problem.

For a time, this dull digital table content, which seemed dizzy to other colleges and wizards, became the most concerned content of every Ravenclaw student-in the face of the temptation to go home Horned beasts, secret passages, and food are all secondary, and they are about to forget what a soft dormitory bed looks like.

This evening, the Ravenclaw dining table is undoubtedly the most joyful place in Hogwarts. Every little wizard has a pure pride smile on his face. Everyone enjoys the food in a relaxed mood and never has to think about tonight. How to enter the door.

In addition, the nine-nine multiplication table full of mysterious beauty and mathematical rhythm has also become the most discussed thing among Ravenclaw students-almost everyone from time to time bowed his head and meditated a few words, feeling carefully After the optimization of the algorithm, the essential leap in computing speed is brought.

But this time, it made some other three colleges somehow inexplicable.

Due to the difference between interest and college atmosphere, apart from Ravenclaw College, there are few other college children who can understand the fun of the digital maze.

You know, although the little guys in Ravenclaw would sometimes have some difficult and philosophical words from time to time, at least it still sounds like "human words" that can be understood, and this is less than half a day. The entire academy has become an ocean of mathematical enlightenment.

Slightly closer, you can hear it. From time to time, small wizards whispered the words like curses in silence.

"One for one, one for two ..."

"Two threes get six, two fours get eight ..."

Not that Elena did any magic in the magazine.

The main reason is that the calculations used in the magic world or in Europe are too weird before. Normal addition and subtraction are fine, but when it comes to multiplication and division, the whole style of painting begins to become cheerful.

Whether it is a table of ten-binary multiplication formulas derived from the British mainland, or a decimal multiplication calculation method introduced from the East, it is usually something that will not be touched until the A-level, and before that there are A level called the GCSE.

But even for the first exam, you still have to wait until you are sixteen in the non-magical world.

For children in the magic world, this time is actually equivalent to the age of the sixth grade students of Hogwarts. It is conceivable that even if the math progress from the non-magic world is synchronized, it will not be What a profound knowledge.

In fact, if Elena remembers correctly, even if you have entered the preliminary examination stage, British students are faced with "complex multiplication", that is, multiplication operations with more than two digits, in addition to using a calculator (obviously , Hogwarts does not support this form), more rely on the legendary line drawing method.

What is the line drawing method?

For example, roughly 12X11, then the British children will draw a vertical line, representing 10, and then draw two vertical lines, representing 2, "12" is like this: (picture.jpg)

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

Then start to find the intersection of these lines, start counting the points from the lower right corner, the intersection points from the lower right corner to the lower left corner, the unit is one, ten, one hundred, one thousand, ten thousand: (picture 3.jpg)

When counting, if there is a situation that exceeds 10, just enter one and mark it next to it.

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

In fact, this kind of algorithm called "linear algebra (pseudo)", although it seems a bit happy at first glance, for British children who hate rote memorization, they only need to count a little bit, and do n’t have to remember what is complicated and difficult to remember. Multiplication table.

In fact, in the original work, when Harry and Ron and others calculated the trajectory of the stars in their astronomy class work, the horizontal and vertical crossing lines on the sheepskin spread on the desktop were doing multiplication drafts.

However, the only small problem with this method is that as the number expands or the second half of the singular appears frequently, just a few dots can give people a feeling of dying-for example 998 When something like 777 multiplies ...

Perhaps in the eyes of the Gryffindor lions, the cheerful drawing of lines is still the most comfortable way of calculating.

But for Ravenclaw students who have a higher pursuit of wisdom and skills, similar to this kind of mastering algorithm keys, they can solve more cumbersome problems and find the correct answer faster, which is undoubtedly the most fascinating. presence.

At least one of the most obvious changes is that, as long as they master the mathematics divination and astronomy classes from now on, their Ravenclaw will far away the students of the other three colleges-whether it is the speed of calculation, or Is the calculation accuracy.

In this way, in a joyous and happy atmosphere, the little wizards of Ravenclaw whispered and left the Hogwarts Auditorium at a brisk pace while silently carrying the "Nine Nine and Nine Multiplication Table". Both are flashing a daydream about a better future.

Very good, it seems that the Ravenclaw Kitty has already tasted a little sweetness.

Elena glanced at the Ravenclaw students who were addicted to the charm of mathematics, and her mouth slightly raised happily.

In the next time, she will secretly ask the house elves to update some question banks next to the eagle ring at Ravenclaw College, but the overall difficulty is constant and can be solved by the nine-nine nine multiplication table. Some basic math questions and answers That's it.

Just like fishing on the lake, if it is too rough at the beginning, it is easy to scare these timid children away.

Only a little bit of bait is thrown in first, so that they have tasted some sweetness, and when they are full of confidence in themselves, it is the real opportunity to open the door to the mathematics hall for them.

Of course, for Elena, these are just issues that need to be slowly polished in the subsequent influence of the fermentation of the magazine, and they are not in a hurry to arrange everything in a short time.

After being busy for a whole week, she just wanted to eat, drink and be a witch with nothing to do.

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

In addition to Elena and her little wings, the Weasley boys who provided the manuscripts, the school bullies of various colleges, and even the castle administrator Argus Filch also received invitations.

While celebrating the successful publication of "New Singing Contrary", Elena also paid on-the-spot payment for this week's manuscript.

With the aroma of the barbecue, the fragrance of butter beer, and the nice sound of Jin Jialong Ding Dang Dong, even the always harsh Argus Filch showed a smile.

Having been an administrator at Hogwarts School of Witchcraft and Wizardry for so many years, he has never been so concerned by the magic world.

More importantly, Elena Caslana is too generous to shoot. With so much extra income, he can finally consider repurchasing a whole new set of cat toys and cats for Mrs. Lorris. Sand pot and cat litter.

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

This is still true of Argus Filch as an adult, not to mention the little wizards who have not graduated, everyone is excited, even the always stable Percy Weasley ca n’t help it. On the kitchen floor, he showed his singing voice, and the brothers George and Fred joined hands for a tap dance ...

Facing the rare lively and cheerful scene in the kitchen, Elena, who is responsible for the barbecue at UU Reading www.uukanshu.com, narrowed her eyes happily, turning the barbecue in her hand while humming quietly, no one had heard of Song melody.

Not far away, Hermione, under the guidance of Hannah, should circulate awkwardly with Argus Filch ’s two-handed tempo, while avoiding hitting the twin brothers of Weasley twins, while being careful With a nervous expression on his face, he had just learned the jazz dance.

In the lively kitchen, a white light flashed from time to time, it was Luna holding her beloved camera to capture the precious moment she thought was worth keeping ...

Amidst the joyous laughter and the aroma of barbecue, the first day of "New Singing Contrast" was released with a perfect ending.
