"Isn't there something ...... number theory?"

Pu Tong didn't expect Ding Lingling's notes to be so profound, although his learning progress was far ahead of most of his classmates, it had not exceeded the scope of high school.

But at his level, it is obviously not enough to touch the high school math league, which is why he is so eager to study the notes of the big guy.

I have to say that Ding Lingling is simply a genius, if she is talented, she is definitely one of the people standing at the top of the pyramid.

This kind of academic sensitivity is basically talent, maybe an ordinary person can do well in the exam through hard work, but when it comes to the level of competition, it is completely a double competition of talent and foundation.

"Xie Mu, what kind of monster did you kid find......"

The more he flipped through his notes, the more frightened he became, the past questions that appeared in these notes, Ding Lingling's answers often had more types than reference answers, she could write four of the three answers, and she could write five of the four answers.

This guy must be an innate math holy body!

In the last half day of the National Day holiday, Pu Tong's whole person was immersed in these strange topics, and he was simply abused to death.

He didn't come back to his senses until the next day, and his mind was still full of all kinds of messy formulas and theorems.

"Little brother, what's the matter with you, can you still be like this after a vacation?"

Lin Yuxi and Iori Xueno went to the magic capital for a few days, and the whole person was a little lively, and Shibei actually had a feeling that the more he thought about it, the better he looked.

No wonder there is a saying called the eighteen changes of women's colleges, adolescent girls are really the same day by day, and they become stunning beauties in a blink of an eye.

As for Yu Yun, it can only be said that she is already good-looking, don't want it, and she is so beautiful that she naturally can't improve.

Don't ask, asking is to entrain.

"Nothing, did you know that transformations are equal to power coefficients?"

“？？？”

The three women glanced at each other and decided not to pay attention to this crazy guy, they are just salted fish who eat with their faces, how can they know this.

Pu Tong rubbed his eyebrows, maybe he was really stupid by the problem, seeing the three beautiful girls talking and laughing, there was no wave in his heart, and he even wanted them to help him solve the problem.

What annoyed him the most was not the problems of those competitions, but a sentence that Ding Lingling sent to him later.

She said that it is better not to use over-the-top college knowledge in high school math competitions.

But the strange thing is that many of Ding Lingling's problem-solving methods use university knowledge, but she asked herself not to use them.

In fact, he can also understand that since it is a competition, there will definitely be rules, and the high school mathematics league naturally considers the thinking and knowledge system of more high school students.

It's like it's obviously a novice village's everyone's fight, and you use the high-level equipment of the big world to abuse the vegetables, which is obviously inappropriate.

Ding Lingling didn't expect to show others when she took notes at the beginning, so she naturally exhausted her brain to exhaust all kinds of methods, but it was not necessarily suitable for taking the exam.

In the final analysis, it's okay to use these things to expand your thinking, but if you really keep digging upwards and forget to lay a solid foundation, you will lose sight of one thing or the other.

The hand holding the pen trembled slightly.

This is actually the first time he has felt the challenge since he studied hard for so long, and the problem is difficult enough, and the moment he solves it is more interesting.

Pu Tong is indeed a little stunned, just study non-stop after class, even in Chinese class is there holding the sketch book non-stop, but the Chinese teacher is quite serious about him, so naturally he won't say much.

To be honest, Chinese teacher Lu Yuan feels that he is not qualified to teach Putong Chinese, his few lines of poetry and a few words, it is enough to be an honorary professor of the School of Literature, and he still needs to listen to lectures here?

In his class, as long as Pu Tong doesn't affect others, he doesn't want to care about what he does......

"Be careful, the next class is an English class, you don't dare to do that." Yu Yunjun reminded: "The head teacher is the same. ”

This has to mention the difference between Zhang Bin and Yan as a teacher, Pu Tong's current achievements are basically sideways in the school, even if the principal meets him, he will smile and chat.

Only their homeroom teacher, no matter how good Pu Tong is and how famous he is, he always treats Pu Tong as a student and is equally strict with him.

Everyone else treats Pu Tong as a treasure, but he, the head teacher, will scold him for his long hair.

Although it seems that Zhang Binyan is a little unkind, everyone also knows in their hearts that he is a truly conscientious teacher.

"Got it......"

Pu Tong put down the pen and rubbed his eyebrows, he really didn't dare to mess around with the head teacher's English class, no matter how good you are, being too self-conscious in class is actually a little disrespectful to the teacher, and Zhang Bin Yan will definitely say him when the time comes.

Forget it, take this opportunity to relax.

"Why don't you wait until the exam is over this week, don't mess up the exam because you're preparing for the competition." Iori Yukino sighed, "There is a first come and first come for everything, so let's review the exam first." ”

"Makes sense...... Pu Tong nodded, "So did you review?" ”

Iori Yukino smiled and said nothing, how could she review, life is only a few decades, wouldn't it be a waste to spend time on this kind of knowledge that will not be used in the future? Eating, drinking, sleeping and sleeping is king.

"You've changed, you'd be ashamed of not reviewing."

In the past, Iori Yukino was a rational lazy, knowing that he was not right to put it badly, but he was really lazy to move.

But now, she has become a wise lazy, not only to put it badly, but also to convince people with reason and evidence!

Is this the evolutionary step of salted fish?

During the English class, Pu Tong still couldn't calm down, and those abstract numbers and symbols were still floating around in front of his eyes repeatedly, making his head rise a little.

"Oh no, it's really in the brain!"

It seems that he has been abused by these things too many times, and now he closes his eyes to all kinds of geometry, algebra, and proof......

"You're stressed."

Yu Yunyun also understood that Pu Tong had never been abused in his daily studies, and the abstraction of these topics made him want to win, and he had to overcome the problem, but over time, he was a little caught in it and couldn't get out.

"You're in love!"

The three girls said in unison, and Pu Tong was enlightened, okay, this is what happened in the original madness.

Think about it carefully, I usually only want to improve myself when I study, and I don't have too much utilitarianism, this time it seems to be a little too competitive, young people, there will always be an occasional impulse once or twice, no way.

"I didn't put too much pressure on myself, relax and relax...... Yu Su stopped talking and added: "Don't forget the agreement!" ”

Conventions?

Pu Tong was a little dizzy by the competition topic, and after she said this, she remembered that she had made an appointment with Yu Kun to "go head-to-head" in the old school building.

Of course, heads-up is fake, but dating as a young couple is real, and I haven't seen each other for so long, and I have to live a two-person world.

"Promise, what promise?"

This kind of mysterious secret whisper can't hide the eyes of Iori Xueno and Lin Yuxi, how can you forget them if you eat melons or something?

Pu Tong and Yu Kun glanced at each other, and finally found a quiet place to live in the world of two, how could they be disturbed by the two of them.

"We made an appointment to go to each other's house together for the New Year."

Pu Tong lied without a draft at all, and even briefly quoted Xie Mu's New Year's plan, and the whole statement was seamless.

Yu Yunjun nodded, although this plan was a nonsense he made up, but it sounded pretty good......

In extracurricular activities, the two went out in batches again in order to hide people's eyes, and Pu Tong even brought Olympiad notes to act like a little, and pretended to ask the teacher if there were questions he didn't understand.

"It's been a long time!"

Walking side by side on the gravel road of the old campus again, the two of them felt a little like a world apart, the embarrassment when they first came here to meet was also strange and clearly visible, but now they can walk hand in hand.

"Actually, when you stood in front of me and argued for me, I already liked you a little......" Pu Tong rubbed his warm little hands, and for the first time opened his heart to talk about his little boy's thoughts.

Just ask, when you see a girl standing in front of you to protect yourself, what boy won't be moved?

"It's so early, then you can really bear it, it took four months to confess," Yu Su saw that there was no one around, and immediately hugged his arm.

"Is the competition really stressful......" She looked up at Pu Tong, her long eyelashes flickering, "How about I help you relax?" ”

"What the hell?"

Pu Tong didn't react a little, this is a small forest, are you relaxed and serious?

Yu Yunyun couldn't help but say, and immediately pushed him half-pushed and half-pushed him down on the stone platform next to him and sat down......

Then I helped him rub his shoulders.
