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

"Fortunately not...?"

"Principal, your landline phone, the signal is not good?"

Principal, "Impossible! Impossible that the signal is not good! It's always been good! It's very good!"

Xu Heng, "???"

At this time, Cheng Kaizhuang took a breath and came back to his senses, "Hiss...Student Xu Heng? You, you, how long did you just say?"

Xu Heng, "Two days? Eh...do you think it's too long? I think it's too long too! One and a half days...or hurry up, one day should be fine."

What the hell!

FUCK FUCK!

Fuck, fuck, fuck!

"Wait, wait! Wait! Xu Heng! Do you know what you're talking about?"

Xu Heng, "???"

The directors said, "Student Xu Heng! This is the [-]th provincial joint exam! A mid-term exam! A second-mode exam!"

"One day? Can the test paper be released in one day?"

"Student Xu Heng, this has nothing to do with the provincial exam, and..."

Xu Heng, "Um... I have participated in the national Olympiad competition, and I have also participated in the provincial nine-school joint exam, but I think, in terms of time, it can indeed be compressed and compressed!"

That's right!

Xu Heng is experienced!

"Besides, I'm thinking about you too! Think about it! If the number of days is too long, you can discuss it with Peking University, and they will definitely disagree!"

"Although I agreed to you! But! I must follow the instructions of Peking University first!"

"After all, everything should be done on a first-come, first-served basis."

There is nothing wrong with Xu Heng's words!

All the directors were dumbfounded.

"Hiss... just these 18 days... one day, isn't it too hasty?"

Xu Heng, "Uh... Everyone, how long is your plan?"

"It's reasonable! Teachers from nearly 20 provinces are working together to produce papers. The efficiency should be higher!"

puff-

Meng Xuejiang, "Student Xu Heng, you don't know about this!"

"The test papers of more than a dozen provinces have always been of different difficulty and difficulty! Especially the college entrance examination papers, there are all kinds of them! Therefore, it is difficult to unify..."

Xu Heng, "It really is a mess! Puff..."

Directors, "???"

"Uh...Xu Heng student...this..."

The group of directors immediately reacted and made a decisive decision, "Student Xu Heng, don't worry! We must communicate with them well! The direction of the question is all up to you!"

"On this point, we will definitely agree!"

They were afraid that Xu Heng would go back on his word.

Otherwise, the [-] provinces entrance examination this time would be a joke!

Seeing everyone's kindness, Xu Heng couldn't turn it down.

"Okay! That's it! You can contact Peking University!"

"Tell me the result later."

Anyway, the midterm exam is still a month away, so Xu Heng is not in a hurry.

pat!

After hanging up the phone, Xu Heng said, "Principal, if there's nothing else, I'll go back first?"

"You just fell, are you okay? Do you want to accompany you to the infirmary?"

The principal smiled, "No, no, no! I'm fine."

"It's just...Xu Heng, I want to ask you, are you joking when you say one day or two days, or...you are intentionally making things difficult for them!"

"Actually, if you directly refuse..."

Xu Heng frowned, and became serious, "I didn't think I was really making things difficult for them. In fact, if the efficiency of publishing papers is high, even if there are more provincial exams, in fact, the papers we are going to issue are Isn't it just nine test papers?"

"It's the same nature as our nine-school joint exam, right!"

The principal was speechless.

Xu Heng, "There are many people, so we should give full play to the value of the number of people! If it is not helpful, then there is no need to call it the [-]-province joint exam."

Principal, "Um...!"

"Hiss...so, you really...really think that you can finish all the joint exam papers in a day or two? You have to take care of the exam paper styles of nineteen provinces!"

Xu Heng smiled, "Principal, are you thinking too much?"

"Stop talking, goodbye!"

Halfway through speaking, Xu Heng left.

Only the principal was left hesitating to speak in the principal's office.

"*%￥#@￥#￥..."

Xu Heng, who came out of the principal's office, swiped his phone.

"Ring Ling Ling..."

The school bell rang.

Xu Heng looked at the things on his phone and couldn't help frowning. He instinctively avoided all the teachers and students and went back to class.

Every class he passed by, no matter if it was a freshman, a sophomore, or a senior, all looked sideways and envied him.

Nima!

This is the absolute legend of learning!

In the future, even if Xu Heng has graduated for many years, I am afraid that his name will still be circulated in Yunshan High School!

Not only will he be mentioned by teachers!

Students will also pass it on. They will say that there was once a senior who could ignore the school rules and play with mobile phones, which was his normal state.

He can play with his mobile phone during class, hold his mobile phone after class, greet the teacher with a smile, and...

In the eyes of teachers and students, Xu Heng no longer looks like a student!

Not just a student anymore!

Xu Heng returned to class.

After coming out of the principal's office, he was watching a video.

This short video says: What is the use of mathematics in daily life?

This aroused Xu Heng's doubts.

What he wonders is, what is the impetus for the retarded author to make such a post?

The person who posted this short video did it for traffic?

But even though he was doing it for traffic, some people really only think that mathematics is addition, subtraction, multiplication and division, and the rest are useless.

Back in class, Xu Heng sat down and asked Yue Pingting and Yang Kaixuan, "Do you think mathematics is very useful in life? In other words, is mathematics useful?"

Yue Pingting was dumbfounded by the question.

So did Yang Kaixuan, "Should... be useful, right?"

But also very unfounded.

Xu Heng shook his head helplessly.

Sure enough, their knowledge of mathematics is limited to this.

Yue Pingting, "It seems to be true. For some trivial matters in life, it is enough to learn addition, subtraction, multiplication and division."

"I think the formulas we learn in high school are not used at all."

Yang Kaixuan sighed, "Let's not talk about high school, even junior high school, you don't need it!"

"Not even elementary school ones!"

"We don't encounter chickens and rabbits in the same cage. We have time to count the number of heads and feet of these animals, but we don't have time to separate the number of rabbits and chickens."

"Nor will we encounter a little Ming who runs faster than a motorcycle and chases a train."

"We will never encounter a large water tank full of water, and pour water into it while filling it, asking when the water can be drained or filled."

Xu Heng asked, "If there were no 12-inch pizzas in a restaurant, and I gave you an 8-inch pizza and a 4-inch pizza, would you be willing?"

The sudden question stunned Yue Pingting and Yang Kaixuan.

Yue Pingting was confused and scratched the back of her head, "Shouldn't there be two 6-inch ones?"

Yang Kaixuan was indeed cautious, but then nodded.

after all……

None of them combined this thing with math!

In their cognition, these are part of life, rather than using mathematical calculations to calculate the situation.

Xu Heng shrugged helplessly and drew a circle on the paper.

Obviously, the 12-inch thing is much bigger than the 8-inch and 4-inch things combined!

Xu Heng didn't say a word, but just drew three circles, which immediately made Yue Pingting and Yang Kaixuan understand.

Only then did they realize that they had to use what they had learned!

After all, it's not difficult at all!

岳娉婷，“一个12寸的，大概需要2个8寸的、1个4寸的才够！”

Yang Kaixuan, "Or one 8-inch one, five 5-inch ones!"

Indeed it is!

Yue Pingting added, "I want four 6-inch pieces! My God! I almost lost money!"

"This group of waiters, good or bad..."

Xu Heng reminded, "Maybe they didn't even notice it themselves."

Yang Kaixuan spread his hands, "But what else?"

Yue Pingting, "This..."

The two of them focused their attention on Xu Heng at the same time.

Xu Heng organized his words, "Let me tell you this..."

"There is such a big company with nearly 1 employees. It is almost the fifteenth day of August. Their big boss wants to buy a box of mooncakes for each employee. Then there is a factory downstairs. This factory is directly One box of mooncakes sells for 100, two boxes of mooncakes sells for 160, and three boxes of mooncakes sells for 200.”

"Then the boss thought that three boxes of mooncakes cost 200 yuan, and one box was less than 70 yuan. If he negotiated the price to 60 yuan a box, it should be about the same."

"So he gave 60 yuan to his assistant Xiao Li, saying that the three boxes of mooncakes cost 200 yuan, and you can negotiate the price of the other box to 60 yuan!"

"The 60 yuan just bought 1 boxes of mooncakes, enough to distribute to our employees."

"If you can cut this price even lower, then it will be reflected in the year-end bonus!"

"As soon as Xiao Li heard about it, he took the 60 yuan and went to the factory."

"If you were Xiao Li, how much would you talk about the price?"

Xu Heng looked at Yue Pingting and Yang Kaixuan.

They glanced at each other.
