All-round mathematician

Chapter 5 The Beauty of Mathematics
"Congratulations to the host for achieving the first book proficiency. Please choose a character to draw a lottery or add a little attribute."

Listening to the pleasant reminder, Yang Fan felt that all his efforts were not in vain.Fortunately, I woke up early and chose biology instead of mathematics.

Why, mathematics is such a mouthful to read.Letters and numbers are interlaced, so it is impossible to read fast.As for creatures, they are all very ordinary sentences, with many graphics and few words

No, in less than a week, I actually finished a book.For the system, as long as it is in line with the current growth, it does not matter whether it is compulsory or elective.Don't forget, the system wants Yang Fan to be called an all-round master, a biologist, and also a master.

Yang Fan preliminarily estimated that after reading biology 15 to 20 times, the proficiency is full. The simpler the course, the faster the proficiency.

Especially after the proficiency reaches 70%, every time you read it, it will grow by 4 to 5 degrees.

"The host please choose."

"I choose to draw a lottery."

A big turntable is formed in the mind, and the turntable is full of densely packed people. The turntable is so big that it seems to break through the world, and the names of people are as small as ants.It can be seen that in the long river of history, master figures have a lot of cars.

"Stop." The turntable turned a few times,
"The choice of character is confirmed, 17-year-old Wang Xizhi."

Not bad, Yang Fan is very happy, the young Wang Xizhi, calligraphy is much better than himself who has never started.

In the next 40 days, Yang Fan was lucky enough to draw three more, winning the 21-year-old basketball king Jordan, the 11-year-old singer Mike Jackson, and the [-]-year-old Li Yuanba.

They are all extremely awesome characters, Yang Fan is not willing to use them directly, and save them first.

Seeing that it was almost the end of September, it happened to be a Friday. Mathematics teacher Chen finished his lecture and said at the end: "Everyone pay attention, everyone must have heard of Feng Yao, the mathematics teacher who teaches senior one. Tonight, I will be in the lecture theater. The high school Olympiad League students are specially trained. You can participate in anything."

What this means is that if you have no confidence and ability, don't make a fool of yourself.He swept across the faces of the six people who had been called, and left happily after getting affirmative responses from them.

Of course Yang Fan agreed, he didn't have time to do any questions in the set of papers given last time.I heard that several other people have asked Chen Changyi for advice several times, but I am the only one who doesn't care.It's embarrassing.

And Feng Yao is a very famous math teacher.If he is chosen to teach one or two, maybe he can improve a lot.

Yang Fan went home, had dinner, and arrived at the auditorium before 7:[-].There will be a holiday on November [-], and there will be classes tomorrow Saturday after the holiday, so there are people in every class.

Yang Fan scanned around and found a few people in his class in the middle, but there were no seats on the side.It seems that I haven't been recognized yet.I found a corner and sat down casually, waiting for the class to start at 7 o'clock.

Feng Yao entered the classroom stepping on the dot, and was a little displeased when he saw the black heads.There are as few as three or five people in each class, and as many as ten or so people. There are high school students and high school students, and it is estimated that there are more than 100 students. Do you think that participating in the Mathematical Olympiad is to buy vegetables?

He graduated from a normal school and went to Mizuki's graduate school. He has an arrogant personality and has been a top student since he was a child.If the old principal hadn't invited him, he would never have been a teacher in this high school.

He still has an unfulfilled wish in his heart. He didn't get a medal in the international competitions in the Mathematical Olympiad that year.Although I had a fever in the past few days due to acclimatization, but failure is failure, no excuses are useless.

Then implement it on the students.For this idea, he is always only willing to teach high school students, because the first year of high school is the easiest to find good seedlings, and they are pleasing to the eye, so he will be taught by his subordinates for two or three years. Unfortunately, there are fewer and fewer people with spiritual energy.

"Listen, you people, how many people you can keep today depends on your luck. If you don't have aura, I don't want any of them. I don't care if you like the Olympiad test or not."

As soon as the words came out, the domineering side leaked.The students were silent, as the rumors were true, they were in a mess arrogantly.I heard that the two high school mathematics classes he took over the years rarely followed the syllabus, and taught wherever he thought of.

The average math test scores of these two classes are also mediocre, but there are a lot of top math students.In every exam, at least half of the top scores are brought out by him.

Some students who have been taught by him in the second and third grades of high school know that Mr. Feng is talented, but teaching is actually not good.The resources are only aimed at top students, and when ordinary students ask questions, he will reply, you are so stupid, how can I teach, ask people yourself, or go to the book.

It's just that he has a personality, and the top student in mathematics still recognizes him.

Feng Yao picked up the chalk and wrote a number on the blackboard: 142857.
"You see the number. It's a very interesting number. If he multiplies 1 to 6:

142857 1 × = 142857
142857 2 × = 285714
142857 3 × = 428571
142857 4 × = 571428
142857 5 × = 714285
142857 6 × = 857142
"How about it? Isn't the answer very interesting? Turning around, it's just a sequence of numbers, and it's also a six-digit number."

Hey, that's interesting.Yang Fan also became interested. This teacher Feng really lived up to his reputation, and his teaching was different from that of ordinary teachers.

All the students in the audience stared at these arithmetic problems, and the more they looked at them, the more miraculous they became.Why is this so.

Feng Yao continued: "Numbers in the world of mathematics have many magical properties. Some are discovered by accident, and some are discovered inevitably. It can be seen that in the world of mathematics, we have just started. Let's see.

142857 7 × = 999999
The sudden change in results caught people off guard.Although I feel very ordinary in my heart, this last topic makes people feel a wonderful sense of beauty.It's weird.

Yang Fan took out a pen and paper, and followed suit in his own notebook, from one to seven, without any mistakes.

How did that happen.Why does multiplying by 7 change so much.It's not just Yang Fan who has doubts, everyone present is muttering in their hearts.

Seeing that the students are very enthusiastic, Feng Yao is in a much better mood. Mathematics is often boring, and it is not as applied to life as physics, and it is not as varied as chemistry, but mathematics exists, and it is definitely the truth.Even to the edge of the universe, it is unique.It's almost a law of the universe.

"The reason why after 7 days, the sudden sublimation makes people feel beautiful again. Some people say that it is because it took 7 days for God to create man, so every person on earth sees the last change, and there will be an alternative sense of beauty from the bottom of his heart."

The discussion became louder in an instant, and the students whispered to each other.Is it okay to teach theology in mathematics class?

"Of course, as a math teacher, I definitely don't believe it. Not to mention, we Chinese have nothing to do with God. Our ancestor is Nuwa."

"Ha ha".

"It's hard to explain why there is such a rule. We should leave such an important task to future generations."

There is also division:

9 ÷ 7 = 1.2857142857142857142857142857
99 ÷ 7 = 14.142857142857142857142857142857
999 ÷ 7 = 142.7142857142857142857142857
……

Division is the infinite cycle of this number, which lasts forever and from generation to generation.

Dear students, this number, from its appearance, will continue to be passed down until the universe is destroyed.This is the beauty of mathematics. "

The applause sounded. At this moment, the students who were listening to the lecture suddenly realized that mathematics is not just boring. Those numbers are really beautiful.Teacher Feng Yao NB.

Yang Fan clapped his hands excitedly, and suddenly felt that mathematics is so interesting, why didn't he realize it before.

Feng Yao lightly pressed the air several times with his hands, the applause stopped, and he said again: "I am actually very opposed to cramming mathematics education, which completely shatters the interest and aura of the students. It's just that the environment is such that I can only I can follow the trend.

I hope that all students will remember the achievement and love when they first came into contact with mathematics and made 1+1=2. "

There was another round of applause. Feng Yao is a teacher with a real personality. If you study mathematics in his hands, you will definitely improve.
