The villain only wants to live a Buddhist life

An equation is an equation involving the unknown X.

It is not a profound knowledge point, but a simple calculation tool.

Solving equations can avoid the difficulty of reverse thinking, and directly list the equations containing the quantities to be solved.

For the application of basic equations, the most popular one is to solve the problem of chicken and rabbit in the same cage.

Duck just quickly explained the knowledge points he knew, and Professor Lily realized it instantly!

She quickly said: "A similar method has been mentioned in the "Genelo Canon", but it has not been integrated into a system. Using this method can indeed simplify the calculation. Although I can't use it...emmm, it can go deeper Some, tell me?"

Duck asked curiously, "What is the Canon of Genelo?"

Professor Lily: "An ancient sect that worshiped geometry has probably been reduced to ashes by now."

The corner of Dak's mouth twitched: "Is mathematics taught?"

Afterwards, he followed Professor Lily's request and went a little deeper.

"Equations come in many forms, and what I just talked about is just a linear equation in one variable. In addition, there are linear equations in two variables, quadratic equations in one variable, etc., and you can also form a system of equations to solve multiple unknowns..."

When it comes to quadratic equations in one yuan, we have to talk about powers, that is, "powers".

With the definition of "power", it is necessary to mention "base number", "exponent", "square root"...

Duck said it smoothly, and Professor Lily listened carefully, and a basic model about mathematical operations gradually took shape during the communication between the two.

The further back, Professor Lily's heart became more and more shocked.

From the introduction of the concept of "power", she found some extremely complicated calculations. After using "power", it seemed that a straight road was suddenly folded, making the qi point and the end point suddenly close!

Obviously, this is a concept far beyond addition, subtraction, multiplication and division!

Professor Lily originally only wanted to extract an algorithm like the "vertical calculation method" from Dak, but he did not expect to get something even more remarkable.

After thinking carefully, she suddenly took out a pen and paper from the drawer, wrote out various complex problems out of thin air, then introduced the concept of "power", and then solved them with equations.

"Void!"

She looked up with a rosy face, but found that there was no one on the sofa.

……

In order not to go to the history of magic class in the afternoon hungry, Dak chose to stop in moderation and yo-yo in the middle.

Seeing that Professor Lily can infer other things from one instance and master them well after just understanding some definitions, Darke is actually a little envious, maybe that is a real genius!

When he came to the cafeteria, he ordered a steak and mince pie, ate it quickly in the empty cafeteria, and then hurried to the History of Magic classroom.

When he entered through the back door, the classroom was already full of people.

Werther and Robert, who were sitting at the back door as usual, looked over curiously, and were surprised that he came so late.

But Werther already had some hostility towards Dak in his heart, and he had given up his plan to increase his favorability, so he didn't talk to him.

Robert didn't have such scruples, and said on the spot: "Hey, Duck, where are you going? You're only here now."

Darke turned his head and smiled, "Discussed some issues with Professor Lily."

Robert; "Oh."

Werther still couldn't help asking: "Is it related to the class in the morning?"

"Yes." Duck nodded, then moved on, and quickly returned to his seat.

Not long after, the bell for class rang.

Professor of the History of Magic - Ryan Hacks walks in on crutches

He still wears broken prosthetic limbs and walks with a limp, but the expression on his brows and the temperament of his whole person are quite different from when he came here.

Just a week of college life has allowed him to get rid of the strong twilight atmosphere, and his brows have also regained some hardness.

But what attracted the students the most was his almost bald head—it had grown out!

"professor!"

A knight academy student in the front row couldn't help raising his hand and said, "Your hair?!"

Professor Ryan Hacks raised his intact hand, pulled back his dark brown bangs, and said with a little pride: "Theodore, you need to relearn what is polite."

"Okay, Professor." Theodore muttered and sat down.

Only then did Professor Hacks say: "I just did an experiment with Sister Carlian. Oh, she called it a hair growth potion!"

"It turned out to be a little white mouse..."

Duck, who was in the last row, blinked, thinking that it would be better for Professor Hux not to be too happy too soon.

If the hair growth potion could be researched so easily, there wouldn't be so many bald heads among the great nobles.

However, Professor Hucks, who has a head of thick brown hair, really looks like a handsome old man after he shaved off his beard.

After Professor Hacks stepped onto the podium, he continued the content of the previous class and continued to tell the unfinished war stories.

It's a pity that when the golden generation headed by the brave and others were active on the battlefield, Professor Hux had already retired due to injury. Although he knew the battles that he didn't personally experience in detail, he lacked some details after all.

So he talked more about the early battles. At that time, humans had no advantage, and every victory had to pay a heavy price, but the significance of each victory was also unprecedented.

But Professor Hacks's lectures in the last two lectures were all battles that were won in the end.

In this class, he seems to have changed his mind.

15 minutes after class starts.

Professor Hacks said: "There are victories and losses, that is war. We gain experience from victory and learn lessons from failure. The so-called history of war is also a history of sacrifice. I will always remember the sacrificed comrades, and Those who betrayed in war will never be forgiven!"

He seemed to have thought of something, and quickly clenched his fists to cover the ferocious corners of his mouth, then calmed down, and continued: "The battle to defend the Ghost Cow Tribe! It was a mournful battle in the history of modern warfare, and it almost broke the Alliance of Hundred Clans!"

The students in the audience couldn't help paying attention.

Professor Hacks always takes a very personal approach to his lectures, but that makes it all the more engaging.

Even Dak couldn't help listening.

The battle to defend the Guiniu Tribe was a battle that took place at the beginning of the signing of the "Hundred Clans Alliance Treaty".

The ghost cow clan among the orc clan called for help from the alliance at that time.

After the urgent discussion, the alliance immediately regarded it as a key battle symbolizing the alliance, and dispatched an alliance army composed of four major races: orcs, elves, dwarves, and humans, to rescue the ghost cow.

And Professor Hacks is in it!
