Chen Lingxiao's words made the scene silent, death-like silence.

Whether it was Ma Yanming or the other students, they all stared at him intently.

There is expectation, mockery, and ...... in those eyes

In short, it's complicated.

Ma Yanming came back to his senses and smiled angrily: "Chen Lingxiao, according to what you say, my superintendent is redundant to you?"

"Well, it's redundant!"

Chen Lingxiao didn't save face for the other party, and went back seriously.

The students in the classroom couldn't help but laugh out loud when they heard his words.

Ma Yanming's face was even more pale, and he glared at those students viciously.

They hurriedly suppressed their smiles, and their faces turned red, so uncomfortable.

He provoked the king of Mahama, but there was no good fruit to eat.

I heard that the prince who once came to Taixue to study was beaten by King Mayan, and this product is also good enough.

They don't dare to work hard with each other like Chen Lingxiao.

Mathematics is an extremely difficult subject.

"Hmph, Chen Lingxiao, you are amazing, very powerful!"

Ma Yanming resisted the urge to go up and beat Chen Lingxiao, and said coldly:

"If you can solve my question in a quarter of an hour, you won't have to use it for the superintendent's class in the future.

If you can't answer, the superintendent will not only beat you with 120 boards, but you will also kneel at the door of the superintendent's room for three days and three nights, and slap yourself three hundred times a day!"

Chen Lingxiao grinned and said:

"If I can't solve it, I'm going to be punished so much. I figured it out, just don't come to your class, it's a bit too ......"

"What's too much?" Ma Yanming said.

"It's so unfair!"

"Tell me, then, what do you think is fair?"

A smile appeared on the corner of Chen Lingxiao's mouth, and he said:

"If, within a quarter of an hour, I have solved all the problems, I don't want the Superintendent to kneel down and sing Conquest, and you won't be able to sing it anyway.

I'll hang a sign around your neck, which says, 'My Ma Yanming is superfluous', and you are not allowed to take it off no matter what you eat, sleep, or go to class, just hang it for three days and three nights."

I wonder if Master Ma agrees?"

"Hmph, this superintendent promised you, a villain who has no teacher, anyway, you are the one who loses!" Ma Yanming snorted coldly.

He is full of self-confidence, he has been immersed in the way of mathematics for decades, and he can't clean up a hairy boy?!

When Chen Lingxiao heard this, he glanced around at the students, and finally looked at Superintendent Ma and said:

"Then let's not let it take time, everyone is still waiting to see a good show.

Come on, just take out your means of pressing the bottom of the box, and don't take out those pediatric ones!"

Ma Yanming looked at the other party's arrogant appearance, his lungs were about to be blown up, and he thought for a while:

"Question: The general points the number of soldiers in a group, two in a group of three, three in a group of five, and four in a group of seven.

Q: How many soldiers are there in this group at least?

In order to prevent the blind cat from touching the dead mouse, you must give the idea of how to solve the problem, otherwise, even if you get it right, it will not count. ”

This question is one of Ma Yanming's specialties, and he has stumped many people with this question.

Therefore, it is difficult for him to take it out now.

When the students in the classroom heard the question, they frowned one by one and thought about it, and they all felt that this question was difficult and difficult.

They want to break their heads, but they can't figure it out.

All the students couldn't help but look at Chen Lingxiao with sympathy and pity, and felt that he should be about to lose.

Then, accept the punishment......

Unexpectedly, in the blink of an eye, Chen Lingxiao gave the answer: "53!"

When Ma Yanming heard this, his brows furrowed slightly, and he said, "Tell me about your problem-solving process!"

The answer to this question is "53", he thinks that Chen Lingxiao must be Meng, and, luckily, the blind cat met the dead mouse Meng right.

In this way, it is still Chen Lingxiao who loses.

Chen Lingxiao grinned and explained:

The problem is to ask for a positive number divided by 3 by 2, 5 by 3, 7 by 4, and hopefully as small as possible.

Let's start with the condition of dividing 3 by 2. The number that satisfies this condition is 3n+2, where n is a non-negative integer.

In order for 3n+2 to satisfy the condition of dividing 5 by 3, n can be divided by 1, 2, and 3 respectively...... Try it in.

When n=1, 3n+2=5, 5 divided by 5 does not need to leave 3, which is not in line with the topic;

When n=2, 3n+2=8, 8 divided by 5 is exactly 3, so it can be seen that the number 8 satisfies both the two conditions of dividing 3 by 2 and dividing 5 by 3.

The last condition is to divide 4 by 7, and 8 does not satisfy this condition.

In this way, we get a number on the basis of 8, so that all three conditions are met at the same time.

To do this, we thought that it would be possible to make the new number equal to the sum of 8 and a multiple of 3 and 5.

For 8 plus any integer multiple of 3 and 5 gives the sum of the sum divided by 3 still leaves 2, and dividing by 5 still leaves 3.

So let's make the new number 8 + 15m, and put m=1 and 2 respectively,... Substitute for the experiment.

When the test is m=3, 8+15m=53, 53 divided by 7 is exactly 4, so 53 meets the requirements of the question. ”

As soon as Chen Lingxiao's words fell, the students in the classroom erupted into discussions.

"Really, according to the method given by Chen Shizi, the answer is correct!"

"This Chen Shizi is too godly, just in the blink of an eye, he got the answer, what is his brain made of?"

"Compared with Chen Lingxiao, our brains are elm pimples!"

"Now, I wonder if Master Ma Xuejian will fulfill the gambling contract?"

Sky Chen's idea of solving the problem is very clear, everyone can understand it as soon as they hear it, and they all know that she answered correctly.

At this moment, Ma Yanming's eyes widened, staring at Chen Lingxiao, without saying a word, stunned.

Seeing this, Chen Lingxiao grinned and said, "Superintendent Ma, I've finished solving it, if you still want to hear it, I still have several ideas, and then I'll explain it to you." ”

“......”

Ma Yanming came back to his senses, his eyes were firmly fixed on Chen Lingxiao, who was full of sarcasm, and he couldn't say a word.

Chen Lingxiao said with a smile: "It looks like Superintendent Ma doesn't want to hear it, okay, please exchange your promises!"

Ma Yanming stood there, his face was blue and red, his chest was constantly rising and falling, obviously angry.

However, he did lose, and he lost so completely that it was not good to attack on the spot.

Although Ma Yanming is usually strict and likes to discipline students, he is also extremely face-saving, and what he says will not be counted like Friday.

Chen Lingxiao glanced at the other party, walked up to a student, and said, "Borrow your pen, ink, paper, and inkstone." ”

"Chen Shizi, you use it, you use it!" the student hurriedly said.

Chen Lingxiao grabbed the brush and wrote down a line of words "My Ma Yanming is redundant", then blew it with his mouth, pulled out a silk thread from his clothes, made a brand, and brought it to Ma Yanming.

When the other party saw this line of words, his face flushed.

If he hung this sign and walked around in Taixue, he Ma Yanming would not lose face.

Thinking of this, Ma Yanming couldn't hold back any longer, and spit out a mouthful of old blood with an angry "wow".

"Ding! Congratulations to the host for completing the task...... Get 500 System Coins!"

The sound of the system sounded in his mind, Chen Lingxiao heard this, and his heart was happy, and 500 system coins were in hand.

Then, he hung the sign on Ma Yanming's neck, and arched his hand at the other party, saying:

"I'm sorry, admit it, make it ugly, give it ugly!"

Wow~

Ma Yan angrily spat out a mouthful of old blood again and fainted.
