"Whew~"

Guozijian, arithmetic class.

A burst of snoring burst out, messing up the teaching spirit of the master under the door.

"Xiang Hanzi!"

"On the first day of school, you go to bed!"

"You've been lying at home for more than ten days, haven't you slept enough?"

Liu Muzhi scolded Xiang Yan bitterly, he only disliked this gentleman.

I still remember that at the beginning of the school year in Guozijian this year, this kid took off his pants in public, and he wanted to compare with himself who was more capable!

On the seventh day of the fourth lunar month, Xiang Yan snatched Liu Muzhi's ring ruler and made Zuo Xiang's second daughter's buttocks red!

On April 28, Xiang Yan was absent from school all day, and before school, he came back with a pig's head and a hornet's nest!

In the months that followed, there were many troubles.

The entire country, from top to bottom, from old to young.

There is Xiang Yan, and it has never stopped from beginning to end!

Liu Muzhi had long wanted to clear Xiang Yan out of the country's prison, but his father's strength was outstanding, and he could only swallow his anger.

But now the situation is different!

In the recent early dynasties, Shengshang repeatedly knocked on the right Xiang Guozhong's poor family style and vulgar style.

In his Liu Muzhi's eyes, this is a signal, a signal that the Xiang family is about to rain and the wind is full of buildings!

", Lao Deng, I'll sleep with me, you tell you, Lao Tzu just came back and you found fault, what do you mean?"

Xiang Yan stretched her waist, and scolded directly without leaving any emotion.

"What do you mean? How dare you ask me what I mean? ”

"How much have you learned in today's arithmetic class? How many questions did you listen to? ”

"This is the Guozijian, if you don't study here, you should scold, you should say!"

"I am ordered by the saints, to hold the books of the sages, and to lead the children of the country, so I have the obligation to urge you and spur you!"

Liu Muzhi deserves to be a great literati.

Rhetoric, clear logic, full of thinking.

Xiang Yan smiled disdainfully.

If you say that I have a bad temperament and want to make trouble, I can still understand it.

But you say that I don't know how to learn, which is a bit nonsense.

Guozijian is talking about some small promotion things.

And...... It's stinky and long, unfocused, and unorganized.

This kind of thing!

For a graduate student whose soul has pierced here.

It's just a drop in the bucket!

"Lao Deng, the things you talked about, the master has long been familiar with them."

"What evidence do you have that the master doesn't study?"

"Talking about chickens and rabbits in the same cage, you think you're terrible, don't you?"

Xiang Yan responded arrogantly.

Liu Muzhi smiled meaningfully, and then pulled the ring ruler out of his waist.

"In that case, then please Xiang Gongzi, give a lecture to everyone!"

"Let's talk about the paragraph I just said, the problem of chickens and rabbits in the same cage!"

Xiang Yan was not used to this old man, and snatched the arithmetic book.

At a glance, classic questions such as [Hundred Monks and Hundred Steamed Buns], [Chickens and Rabbits in the Same Cage]!

It's all in the book.

The conditions and values given in the questions are no different from what you have learned.

The only difference is that there is only one answer to each question in this book.

Moreover, the only answer, without exception, is all smelly and long.

To put it simply, this book is not even as good as Blue Star's junior high school textbook.

Jumbled! Pedantic!

"Then I'll be respectful and obey."

"The problem of chickens and rabbits in the same cage is explained in the book."

"Find out how many chicken feet there are, and then how many rabbit heads there are."

"Synthesize the chicken's feet to get the chicken, synthesize the rabbit's head to get the rabbit, and then add the two."

"This method is like gnawing bricks in a pit, smelly and hard, and out of order!"

Xiang Yan attacked the arithmetic book with disdain on his face, and Liu Muzhi stood aside, gritting his teeth angrily.

This is the easiest solution left by the Great Sage!

Now it's in your mouth.

It's such an unbearable thing!

"To solve the problem of chickens and rabbits in the same cage, there is no need to use the method mentioned in the book!"

"Just remember two mantras!"

"First, it is not difficult for chickens and rabbits to cage together, assuming that rabbits remember it; Assuming that the actual comparison is to look at it, the chicken and the rabbit are exchanged; Divide the difference and count the chicken! ”

Second, it is not difficult for chickens and rabbits to be in the same cage, assuming that there are many memories; Assuming that the actual comparison is to look at it, more and less to change; The difference is divided by the full and the less! ”

The two formulas are calculated separately by comparing the hypothetical method with the actual method.

The sentient beings of Guozijian are all calculated according to the method mentioned in Xiang Yan's mouth.

In less than three minutes, everyone came up with the answer to Liu Muzhi's question that he didn't explain for an hour!

Liu Muzhi's brows tightened, and he muttered in his heart, what this kid said was actually right!

And, no matter how the values change, this method is perfectly applicable!

Could it be ......

Xiang Hanzi specially looked for a master and asked about the problem of chickens and rabbits in the same cage? !

"Hey, don't say it, it's really easy to do arithmetic with this method!"

"It's better to let Xiang Hanzi be the master, haha!"

"That's right, let Xiang Hanzi teach us!"

……

The atmosphere in the classroom is unpredictable.

was still satirizing Xiang Yan's group of wallside grass before.

At this moment, he actually began to shoot Xiang Yan's horses.

"That's it! Don't make a fuss! ”

"Xiang Yan, go back and continue to listen!"

Liu Muzhi saw that the situation was not right, and hurriedly let Xiang Yan get off the podium.

If he really has the ability, let him continue to talk about it, where will he put his face as a scholar of the Great Zhou Dynasty?

If this gets out.

The stupid Xiang Hanzi teaches better than the university scholar's teaching!

Wouldn't it make people laugh off their big teeth!

"Xiang Yan, listen well!"

"Next, the question we talked about is, a hundred monks and a hundred steamed buns!"

"It's also a classic arithmetic problem!"

"One hundred monks are divided into one hundred steamed buns, one big monk is divided into three, and three small monks are divided into one.

"Does anyone know the answer to the question?"

Liu Muzhi looked around, and everyone shook their heads.

Only Xiang Yan looked at him with disdain.

Liu Muzhi learned smartly this time, so he didn't pay attention to Xiang Yan, but lectured on his own.

"Since everyone doesn't know."

"Then let the master solve everyone's doubts!"

"First of all, let's assume that the big monk has a person, and the small monk has a person, and the relationship is listed, then there is ......"

Before Liu Muzhi's words fell, Xiang Yan suddenly laughed and said:

"Master, you are wrong."

As soon as these words came out, they shocked the people of the country!

Xiang Yan, who had just slapped his master's face.

At this moment, he actually said that the teacher was wrong!

Even if he speaks poorly, can he be wrong?

He's a scholar of the Great Zhou University!

The kind hand-picked by the emperor!

"Oh? Xiang Yan, what did I say wrong? ”

Xiang Yan got up, paced and shook his head:

"It's all wrong, when you get an arithmetic problem, the first thing you have to do is not to calculate, but to consider how many situations it has!"

"Like the question of a hundred monks and a hundred steamed buns, how do you know that these hundred monks are not all big monks or small monks?"

"Can you guarantee that there is no such possibility? The teaching is so lax, I really doubt that you are not paying for a bachelor's degree! ”
