Magic Tower Starry Sky

With such a bold decision, not to mention the few great magicians who were facing each other were surprised, even Fern who was sitting beside him was also surprised.

Even if he received help from Balta before, that shouldn't be the reason for agreeing to the invitation so quickly. The remuneration was not discussed, the details were not discussed, just the appearance of being delivered to the door, which is completely different from the previous statement that he vowed to maximize his own interests.

Realizing that he had become the center of attention, especially when the companion beside him gave him the same puzzled look, Lin shrugged and said, "It is our consensus not to teach P language. After excluding that item, the rest of the invitations are all What is it? It’s not that I didn’t talk about it, or it’s about magic towers, airships, and blinking. No one has asked me to teach mathematics. This is the first one. I’m so touched. Tell me about those I know, If you don’t know anything about mathematics, you can continue teaching.”

Although the sayings are all pragmatic, those who invited before directly focused on the knowledge that can be applied. But just like someone's doubts, the most basic foundation is not enough, how far can they go? Thinking of this, a certain person suddenly realized that he had thought less, and asked worriedly: "Your Excellency Kabanbai will not ask me to teach a group of children, right?"

Kabanbai quickly said: "Of course it's impossible. Your Excellency is a great talent. Wouldn't it be too wasteful to teach enlightenment knowledge?"

"That's good." Lin said with satisfaction. As for the lich who was originally puzzled, knowing the thinking behind someone, he no longer raised other opinions.

Knowing that the magician's agreement in front of him was a decision after careful consideration, and it was not made hastily, or to repay favors, Kabanbai felt even more satisfied. He is not only satisfied that the other party really has the most basic qualities of a magician, that is, rational judgment, but also satisfied with his own choice. This magician who kept proposing new knowledge really valued this knowledge the most.

Glancing at his friend Bi Zhan, the other party also nodded slightly.

This person will appear, not just a drop-in. Although the college bears his own name, it was established together with this friend. He also has the right to participate in decisions related to the academy. He was invited here because he was afraid that the magician whom he had been fascinated for a long time might be a liar with a bright surface, so he invited a few more people to find out the details of this magician.

But judging from the performance at the dinner, maybe the etiquette is not in place, but the other party's knowledge level is definitely not bad. Even the two of them can give a clear answer to the questions I have about those few new knowledge. You need to know those questions, but many of them don't know the answers.

Now that this simple interview, which was not considered intrigue, passed, Kabanbai became more determined to invite this person. He, his wife, and his friends stood up cautiously, saluted heartily and said, "Since your Excellency agrees, then I, Kabanbai,──" "Witness, Bijan." "──It is a great honor to invite Gabrash Cui Your Excellency Purwood, become the mathematics teacher of my college."

Listening to the words used by the other party, Lin probably guessed that the college established in the holy city is the same as the Chengguo Eaton College he founded at the beginning, only allowing students to address teachers as 'sir' instead of 'teacher' or 'mentor' .

That is to say, the teacher-student relationship in the academy is still different from the master-apprentice relationship of a real magician. For such a distinction, someone can only agree with it, but not against it. A real master and apprentice has too many responsibilities.

However, since the three gray-haired old men saluted so carefully, it was impossible for Lin to sit ostentatiously and let the other party caress and bow. Quickly got up as well, bowed and said, "I'm very grateful..."

"I object!" A crisp and childish female voice interrupted and stopped everything from going on. Standing at the door of the small salon, a young and beautiful girl approached aggressively. She threw herself into the arms of the great magician Kabanbai coquettishly, and said coquettishly, "Grandpa, I said that if you want to teach mathematics, you don't need to find someone else, just me."

The great magician who comforted the girl affectionately, Kabanbai could only make an apologetic expression and said, "Sorry, Your Excellency, my granddaughter is too rude."

Hearing that her grandfather was protecting outsiders, the girl jumped up and said sharply: "I am not being rude. I know all the books he wrote, and he is better than him. Why do I need to hire a country bumpkin like him?" Taught in our academy."

A certain person didn't feel anything about the girl's rudeness, but was interested in what she said. I know all the books I have written, what books have I written?

"Don't you believe me? Well, let me test you. The multiplication in your book is just a nine-nine table. At most, there are only ten digits multiplied by ten digits. Then let me ask you, multiply 9,728,063 by What is 11,369,697 equal to?"

multiplication? Tens digit times tens digit? What this chick was talking about was probably the primary school textbook that was written for the children of Chengguo? Eton College.

"The answer is 110, 605, 128, 706, 911. You can't answer it. With this level of mathematics, you are already inferior to me. A mere country bumpkin dares to come to my grandfather's college to teach."

"Hehe." It should be those books that came out at the beginning. It is not denied that calculation is very important to mathematics, but that is not the whole of mathematics. It’s just that the other party is the granddaughter of the great magician Kabanbai. Obviously, she can’t be grabbed and spanked directly. Lin thought for a while and said, “Since you tested me with a question, and I couldn’t answer it, then I will also test you with a question OK?" No mistake

"Okay, you can ask. I am a master of mathematics." The girl said proudly.

"So, may I ask, do you have a pen and paper?" Lin asked the waiter beside him.

The great magician Kabanbai nodded, and his housekeeper would naturally fetch a set of pens and paper. Of course, he would not despise the magician in front of him just because of a few words from his granddaughter. He was just curious about how the other party would convince this little girl who was so proud.

He is not the kind of grandpa who only knows how to spoil his children no matter what is good or bad. Some setbacks in the journey of life are the best nutrients for growth. Of course, the premise is that it cannot threaten life. If it reaches that point, he will definitely stop it. But it seems that this magician is not the kind of impulsive person who turns over the table before thinking about things.

However, Kabanbai also knew that his granddaughter's intelligence and talent were not ordinary excellence, but to the extent that even he himself was often surprised and admired. So he and his family also carefully cultivated this child. And such a little genius can't be easily appeased by patting his head like a child.

As for the other party, he was not as angry as others imagined. He just smiled and took the pen and paper, picked up the ruler, and drew on the paper.

Dealing with brats is like dealing with anyone with malicious intentions, if you fall into the opponent's rhythm, you will lose. The best way is to ignore the opponent, because if you sing a one-man show for a long time, you will be easily injured internally; the second best way is to set up another battlefield, find the opponent's weakness, and then hit it hard!

The girl saw what the magician did, but she didn't take it seriously. Instead, she said, "Hmph, geometry is nothing. Whether you're looking for the area or the volume, it doesn't bother me."

Soon, Lin wrote two pieces of paper. He directly handed out the first piece of paper and said, "Come on, this is indeed a geometry problem. It's not difficult, it's very basic, but it's also very important." On the table, said: "This is the answer, and the folded part is the proof process. But I have to say first, the answer is the only solution, but there are many ways to prove it. So just refer to the proof I wrote."

The girl took the paper confidently, flipped through it...then turned the whole paper upside down, and read it again...and repeated several times like this, she suddenly yelled out of control: "Where is this a geometry problem? There are no numbers on it!" After speaking, he slapped the paper on the table. At this time, other people also have the opportunity to see what someone drew on the paper.

It is a right triangle with base a and height b, what is the hypotenuse equal to?

Several veteran great magicians, as well as the waiters who stood by and peeked, were taken aback by the simple patterns and words on the paper. It is true that there are no numbers on the entire sheet of paper. Can this count as mathematics?

Only Fen glanced at it, and said casually: "Oh, the Pythagorean theorem. It's a trick to deceive children." Then she stopped paying attention.

Finn's casual attitude certainly angered the girl. She cursed angrily, and almost rushed forward to compete with the woman who was so beautiful that she was jealous.

Kabanbai grabbed his granddaughter without letting her rush forward. He picked up the question paper with his other hand, thinking about possible answers. From the attitude of the other party, we can know that there is an answer to this, and calculations can be done without numbers. Unless the concept of calculation is different from what I imagined, and the other party once said that all his knowledge is based on mathematics.

Suddenly, with a flash of inspiration, Kabanbai asked: "Is this a variable of the P language?"

Lin sincerely admires the old magician's sensitivity to knowledge horizontal links. However, some problems still need to be clarified and corrected to prevent wrong ideas from being fixed. "In mathematics, I would rather call it 'algebra~www.wuxiaspot.com~ rather than 'variables' in programming languages."

"Algebra, the numbers used to replace calculations. Well, it's really good." From the simple nouns, savoring the meaning behind them, Kabanbai unconsciously reveled in them. Subconsciously letting go of his granddaughter, he flipped through the covered solutions and proofs, and looked at the deduced hypotenuse solution.

Every step in it is clear. Make every step of calculation on the most primitive mathematical basis, that is, addition, subtraction, multiplication and division. To say that the new calculation method is the symbol of square and square root. But explaining it with mathematical formulas is simple, and it can be understood at a glance.

But compared to the deduced hypotenuse answer, the proof method in front of him is the real treasure of knowledge, because he understands the benefits of algebra. Like the P language, he can put any actual number in the algebra, and then he can get the answer directly through the formula, instead of having to re-deduce it every time and repeat the whole process.

At the same time, it also solved Kabanbai's long-standing confusion. Mathematics, as expected, is not just spread out, that thin book, simple addition, subtraction, multiplication and division and exercises. More knowledge can be extended behind it. But now, he finally glimpsed a corner of that vast knowledge. All the emotions were condensed into one word in his mouth: "Good!"
