Cheng Wanyi's exclamation attracted everyone's attention, and a question arose in everyone's hearts.

Could it be that Yang Xiaolei is really right?

Even Zhang Wendi, who had been thinking hard, looked at it.

It's just that he naturally doesn't believe that Yang Xiaolei can figure it out, and even he doesn't know how to solve the problem, how can Yang Xiaolei be.

Seeing Yang Xiaolei drawing a circle, Zhang Wendi sneered and said, "Draw a circle, what is the answer?"

"Is this zero okay? Is your brain full of poop? I've slept and you haven't figured it out yet, this is the legendary elite?"

"Even if you are zero, so what? Is it the correct answer to this question?" Zhang Wendi was naturally unconvinced.

"The correct answer is zero. Cheng Wanyi said quietly, still with an incredible feeling in her tone.

In less than a minute, such a difficult high school Olympiad problem was calculated, and the shock that brought Cheng Wanyi was too great.

You know, when she counted at the time, she was already in college.

The most important thing is that she has always prided herself on being smart, but she was compared to a high-school student who was not good-looking, and the psychological impact was really unacceptable.

"How is this possible? How can the answer to this question be zero? Such a large number, you can know by looking at the mantissa number, how can it be zero divided by nine!" Zhang Wendi immediately shouted.

He has a bad premonition, his scalp is starting to tingle, if he loses, he has to crawl to learn how to bark dogs, then how can he see people!

"You don't even have a good review of the question, what people say is the remainder divided by 9, hehe, it's still elite!" Yang Xiaolei looked disdainful.

Zhang Wendi was stunned for a moment, thought carefully, and looked at Cheng Wanyi.

"Yes, it's the remainder of the division by 9, and you can solve this problem for everyone to see. Cheng Wanyi looked at Yang Xiaolei.

"It's good, Zhang Da Elite, I'll convince you to lose!"

Yang Xiaolei walked onto the blackboard, picked up the chalk, and said while writing: "There is a very interesting place to solve this problem, that is, it is divisible by 9. ”

"They have a common feature, if the sum of the digits on each digit is divisible by 9, it means that this number is also divisible by 9. ”

On the contrary, if the sum of the digits is not divisible by 9, then the remainder obtained is the remainder of the number divided by 9, which is the answer to this question. ”

"Knowing this feature, it's easy to calculate, 1 to 9 together, equals 45, divisible by 9, and so on, 10 to 19, 90 to 99, and finally until 1000 to 1999, are divisible. ”

"Because the 1 on the thousandth is not taken into account, now add them together, which is 999, and the same is divisible by 9. ”

"In the end, all that is left is the numbers 2002 to 2005, and if you add them together, it's 27, which is also exactly divisible. ”

"It's all divisible, and naturally there is no remainder, so the answer is - 0. ”

Yang Xiaolei threw away the chalk very coquettishly, looked at Cheng Wanyi, and said with a smile: "Teacher Cheng, am I right?"

Cheng Wanyi nodded, and said with a straight face: "Yes, it's completely correct!"

"Zhang Wendi, go to the playground, are we all waiting for you to perform?" Yang Xiaolei walked in front of Zhang Wendi, shook his head, and said with a smile: "Elite, hehe, this is the elite!"

Zhang Wendi's face was ugly, blue and white for a while, and the smiling faces of the classmates around him were like knives, piercing his heart.

Seeing Zhang Wendi standing still, Yang Xiaolei smiled and raised the agreement in his hand and said, "Zhang Elite, are you planning to repay the debt?"

"I..." Zhang Wendi stared at Yang Xiaolei, trembling slightly.

He couldn't figure it out, how could Yang Xiaolei be such a garbage so powerful all of a sudden?

How is this possible?

However, if he really went out and ran around on all fours, and he had to learn how to bark, he couldn't do it.

He didn't want to be the laughing stock of the whole school.

But if you don't go, that's a school-wide joke.

"No, I can't run, this is a lifetime of fame!" Zhang Wendi almost gritted his teeth.

Suddenly, he smiled and said, "Classmate Yang Xiaolei, how about we discuss?"

"No!" Yang Xiaolei directly refused, you forced me by yourself, I didn't discuss it with you.

"Okay, since that's the case..."Zhang Wendi sighed, slowly walked in front of Yang Xiaolei, and said, "Okay, I'm willing to bet and lose!"

"If you don't accept it, you can't do it!" Wang Cunye said with a smile next to him.

Yang Xiaolei smiled and didn't speak, stretched out his hand, and signaled that Zhang Wendi could run.

At this time, Zhang Wendi suddenly jumped up, rushed to Yang Xiaolei with an arrow step, and snatched the agreement.

He put the two agreements together and quickly tore them to pieces.

"This time, you can't do anything with me? Without the agreement, what else can you do with Lao Tzu!" Zhang Wendi went out, he really couldn't go out to learn how to run.

Yang Xiaolei didn't make any other moves, just watched quietly.

It wasn't until Zhang Wendi tore the agreement into pieces that he said lightly: "It turns out that this is the result of elite education!

"People are shameless, the world is invincible!" Wang Cunye hurriedly took it.

Yang Xiaolei smiled, this fat man cooperated well.

"You wait for me!" Zhang Wendi snorted coldly, pointed at Yang Xiaolei, turned around and left.

He really couldn't stay any longer, and the contemptuous gazes of his classmates around him made him want to die.

"Okay, everyone is back in their seats, classmates, it's a good thing to promote each other, but I don't approve of betting on this kind of thing!" Cheng Wanyi clapped her palms and said loudly.

"Now, let's get acquainted again, my name is Cheng Wanyi, your new acting class teacher, I'll name you now, Zhang Dandan..."

"To..."Zhang Dandan stood up.

In a blink of an eye, it was time for school to end, and Yang Xiaolei and Wang Cunye walked out of the classroom together.

In the morning, Zhang Wendi's story spread throughout the school.

For a while, Zhang Wendi became the joke of the whole school, and I don't know how many people talked about it in the back.

And Yang Xiaolei has also become a celebrity in the school, no one expected that Yang Xiaolei, who is not good-looking, would suddenly be so good.

"Yang Xiaolei!" Yang Xiaolei, who had just walked out of the school gate, heard someone shouting at him.

As soon as he turned around, Yang Xiaolei frowned, why did she come.

"I'll go, brother, it's a beautiful woman coming to you, you've been very busy lately! Wang Cunye, who was beside him, shouted directly.

"People don't look down on you! If you are told to lose weight, you just won't listen!" Yang Xiaolei said angrily.

"I... What's wrong with me being fat? Am I proud?" Wang Cunye said unconvinced.

Yang Xiaolei ignored him, looked at Shen Ruonan who came up, and asked strangely, "Hello Officer Shen, is there something wrong?"

"Police officer, female police flower?" Wang Cunye behind him, his eyes were full of little stars.

Shen Ruonan did not wear a police uniform, but a casual outfit.

"It's okay, I want to treat you to a meal!" Shen Ruonan smiled with a smile on his face, and the last time Yang Xiaolei saw her, he judged the two of them.

"It's okay!" Yang Xiaolei muttered in his heart, this Shen Ruonan's smile was obviously very reluctant, and his face was full of thoughts, can he be okay?

"No food, I'm going home. Yang Xiaolei said with a smile, he knew very well that it would be absolutely no good to invite him to dinner.

"Don't!" Shen Ruonan hurriedly said, "Okay, I'll invite you to dinner, and I'll have something to do with you by the way." ”

"If you have something to say, I'm very busy, and Sister Xiaohuan is still waiting for me at home. Yang Xiaolei said calmly.

He won't be fooled, last time he was at the police station, this female police officer didn't have a good face, can there be good things this time?

"It's not convenient here, let's go, I'll invite you to dinner, and say while eating. ”

"Not available. The more this is the case, the more Yang Xiaolei mutters in his heart, although he doesn't know what is going on, but this is obviously a Hongmen banquet.

As soon as he thought of this, Yang Xiaolei turned around and left.

In an instant, Shen Ruonan was stunned.

She didn't care how many people wanted to invite her to dinner.

It's rare that she took the initiative to invite someone to dinner, but she was refused.

Although it was only a little boy who was rejected, it felt like it had never been felt before.

"Stop!" Shen Ruonan snorted, and instantly came to Yang Xiaolei's face, blocking the way.

Yang Xiaolei was stunned for a moment, and almost bumped into Shen Ruonan's body.

"I said female police officer, although your scenery is very good, but you can't eat my tofu!" Yang Xiaolei looked at the scenery on Shen Ruonan's chest, and his eyes suddenly couldn't be pulled out.

Shen Ruonan's face sank, took out the handcuffs, and said coldly: "Now there is a case, I need you to assist in the investigation, do you go to dinner with me and explain the case, or I will handcuff you and take you back." ”

"You win, let's go to dinner!" Suddenly, Yang Xiaolei withered.

"Cheap!" Shen Ruonan muttered in a low voice.
