Xueba, I beg you to go and escort him quickly!

Then he looked at Xu Heng, with a little pleading in his expression, "Communicate with Yang Kaixuan more, and share your learning experience!"

Xue Laiyun still gave Yang Kaixuan face.

So I didn't say "Teach Yang Kaixuan more" in front of all the students in the class.

After Xue Laiyun left.

Many students gathered around Yang Kaixuan.

Take a look at the deposit.

"Example of the Mathematical Olympiad Competition... Mathematical Olympiad Competition?!"

"The Math Olympiad competition? The teacher asked you to participate in the Math Olympiad competition! My God! Yang Kaixuan, you want to be popular!"

"Damn it! Our school is able to participate in the Olympiad competition! Yang Kaixuan, you are the first person from our school to participate in the name of the school!"

"!!!"

Shocked, some students looked at Xu Heng suddenly, "Wait a minute! Why isn't Xu Heng, but Yang Kaixuan?"

"Why did the school invite Yang Kaixuan to participate but not Xu Heng?"

"This is very unscientific!"

"Yes! Is it a mistake?"

"Uh... I'm sorry, I'm sorry, Yang Kaixuan! I didn't mean it!"

Immediately apologized, some students realized that what they said was a little hurtful.

Everyone, "!!!"

Brush brush!

All eyes turned from Yang Kaixuan to Xu Heng.

Xu Heng, "Uh..."

Yue Pingting suddenly said, "Xu Heng doesn't want to participate, we talked about it before, you forgot?"

Suddenly someone followed, "It's too simple, right..."

"Pfft!!!"

Everyone is aware of the problem.

Immediately looked at Yang Kaixuan, eyes full of sympathy.

They figured it out, Xu Heng was also called past before looking for Yang Kaixuan.

"Hey... Yang Kaixuan, don't be sad!"

"We want to participate but we can't! What do you think?"

"Look, if Xu Heng doesn't participate, it will be me immediately, we don't even dare to think about it!"

"If it's my turn! Our class probably needs to find half of the people!"

"Yes! Yes! There is nothing wrong with it!"

Depend on! ! !

You are comforting people!

Still hitting people!

　 　"Go, go! You don't need to comfort me here!"

Yang Kaixuan dismissed everyone.

Although everyone returned to their seats, they still looked at him sympathetically.

Yang Kaixuan was the first two people.

I sympathize with your sister!

Isn't Lao Tzu better at studying than you?

Where did your overwhelming emotions come from?

"Normally, I didn't pay attention, but seeing Xu Heng and Yang Kaixuan sitting together now, I'm still impressed!"

"One is found, and no one else is willing to participate..."

"Stop! Stop! Maybe it's not! Maybe the school is looking for Yang Kaixuan!"

"But, there is absolutely no reason not to find Xu Heng!"

"What if people say that Xu Heng won't participate! Who made him so powerful!"

"Damn!!! It's really possible!"

Some people's brain circuits are just different!

Actually led many students to start various brain supplements.

They didn't dare to ask Xu Heng directly in person.

This hurt Yang Kaixuan too much.

Yang Kaixuan was completely speechless.

Xu Heng persuaded, "Don't be as knowledgeable as them. I think you're fine. Ordinary people, even if the teacher finds them, they won't dare to do it!"

Yang Kaixuan smiled bitterly, "Are you comforting me?"

Xu Heng waved his hand, "No, I'm just telling the truth, for some emotional students, I really don't want to."

Yang Kaixuan sighed.

There are mixed feelings in my heart.

It was weird to be consoled by the last guy who turned down the competition.

Yang Kaixuan quickly changed the subject, "Xu Heng, please give me more advice in the future."

"Perhaps for those of us, joining the training team is unthinkable, we can only work hard on our own!"

Yue Pingting leaned over at this time, "Is there a big difference between this Mathematical Olympiad and the test papers we usually do?"

She is Xiaobai!

Xu Heng rubbed Yue Pingting's brain, "Aren't you talking nonsense?"

Yue Pingting, "Ah...%￥##￥%..."

Yang Kaixuan looked at it, and always felt that the relationship between the two was very good...

and many more!

They can't be... that's it!

I rely on it! ! !

I'm not going to be abused like a dog when I get to the last row!

Yang Kaixuan suddenly had no love in life.

He slowly raised his head and looked up at the sky at 45 degrees...

"Hey……"

Xu Heng rolled his eyes.

Yue Pingting, "Eh... what is he doing? Is it the first time in history that he sits in the last row?"

This is all secondary, okay?

The main thing is, you two are ruthlessly abusing dogs!

It's already hard, but let me watch you show your affection!

woo woo woo...

The always strong Yang Kaixuan really broke down.

PS: Thank you [good] [blue] [tail number 4862] for your support!

I wish you 21 years of riches!Get rich!Get rich!

Kneel for all support! ! ! .

Chapter 134

"By the way, how difficult is the Olympiad competition? Is it different from what we normally learn?"

Yang Kaixuan answered excitedly.

"Olympiad requires an understanding of mathematical concepts and theoretical ideas, and often requires special methods to solve problems."

"Because the concepts involved in the Olympiad may be mathematical concepts that students of that age have not learned to solve."

"It is also a question that requires students to use low-level concepts to solve high-level concepts. The process here can be equivalent to the process that mathematicians deduced high-level concepts from low-level concepts at that time."

"It is no exaggeration to say that the Olympiad is used to train mathematicians."

"General mathematics is to memorize concepts and formulas. You just need to apply the concepts and formulas you have learned. The focus is on cultivating mathematical literacy and application."

Speaking of Olympiad, Yang Kaixuan was eloquent.

Xu Heng waved his hand, "What you said is too complicated. Let's put it this way, the Olympiad is not prepared for more than 95% of the people in this world, but... Actually, the Olympiad is not that difficult."

Pfft!

It's not that hard!

"Xu Heng, just stand and talk without back pain!"

The veins on Yang Kaixuan's forehead popped violently.

Xu Heng, "Um...it's quite simple. The audience for this thing is very small, but if someone is very interested, there are still traces to follow."

"For example, there are three typical and basic thoughts in Mathematical Olympiad: the principle of sum and difference, the principle of sum and doubling, and the principle of doubling and difference."

"Of course, this is for the lower grades, and the senior grades are similar."

"Master these, and all problems will be solved."

Yang Kaixuan clutched his chest, not to get too excited.

Yue Pingting listened, and really believed Xu Heng's words, "So it's like this..."

Such a yarn!

Yue Pingting, can you make some basic judgments!

If it is really like what Xu Heng said, why am I the only one in the whole school going to participate in the competition?

"I seriously doubt that you did it on purpose!"

"Are you going to pull the dog over and kill it!"

"Is feeding dog food not enough for you?"

Xu Heng, "Um...a misunderstanding, this is definitely a misunderstanding!"

Yue Pingting, "Hmm! Don't get me wrong!"

Yang Kaixuan, I don't want to misunderstand you, but you guys are really going too far!

In order to change the topic as soon as possible, Yue Pingting hurriedly said, "Yang Kaixuan, can you show me the test paper?"

Get the Mathematical Olympiad test paper!

Yue Pingting widened her eyes, "200 points..."

Take a look at the topic:

Given that i is an imaginary unit, what is the complex number (1+2i)/(i-1)=?

Yue Pingting, "Er...no..."

Look again!
