Happy Boys: More children, more blessings, starting with Song Qian

Chapter 60 Zhu Yun, are you sure this is a serious hotel?! (Kneel for flower monthly passes and evaluation tickets!) ）

After receiving praise from the mentor,

Zhu Yun raised her chin again,

Tsundere looked at Qin Feng,

And then

Zhu Yun said his three solution methods ~ methods one by one,

Hearing Zhu Yun's answer,

The mentor gradually raised his eyebrows,

The surrounding students also slowly showed a cheerful expression, and they all sighed that they could still start from this angle - solving the problem.

But

When Zhu Yun finally said the third problem-solving idea,

The teacher's expression changed slightly,

There is also a trace of puzzlement and doubt in the eyes,

meanwhile

Qin Feng was also slightly surprised, and turned his head to look at Zhu Yun.

The other students were unaware,

Still with the mentality of learning, grasping the time to take notes,

But after waiting two minutes,

Qin Feng and his mentor said at the same time: "Wait a minute! "

After speaking in unison,

The instructor looked at Qin Feng: "Classmate Qin Feng, you also found out?" "

"Yes."

Qin Feng nodded, looked at the instructor and said: "Teacher, in the third problem solving idea just now, the data variable formulas used by Zhu Yun are all wrong, so it will lead to errors in the entire calculation result. "

"Wrong?"

When Zhu Yun heard this, his expression was very surprised: "No, I should be right." Teacher, Qin Feng, these three problem-solving ideas, I have repeatedly verified in my mind in advance, and the results are the same. "

"Is the result of the calculation the same?"

The mentor was slightly stunned when he heard this,

Then I thought about it for a while, and I understood the reason,

However, the tutor did not directly explain,

Instead, he looked at Qin Feng and asked, "Classmate Qin Feng, when the data variable formula is used incorrectly, the final data calculation result is the same, what is the reason?" "

Tutor's questioning,

Let Qin Feng become the focus of the audience,

Many students looked at Qin Feng and discussed various possibilities in a low voice,

And at this time Zhu Yun,

But stared at Qin Feng unconvinced,

She also wondered, why on earth was that?

When Qin Feng heard this, he smiled slightly: "The variable formula is used incorrectly, but the calculation result is the same, and there is only one reason for this." "

"That is, in addition to the correct thinking, Zhu Yun's third problem-solving method is wrong from beginning to end."

"However, due to preconceived reasons, Zhu Yun will constantly revise and change during the problem solving process, so as to ensure the consistency of the final answer."

"How is that possible?!"

Qin Feng just finished speaking,

Zhu Yun loudly refuted, "Teacher, Qin Feng, I can be sure that there is absolutely no problem with my third method. "

"Teacher, I ask for live calculations to prove myself!"

After speaking,

Before the instructor agreed,

Zhu Yun walked down the stairs,

Standing outside the podium,

And turned to look at Qin Feng: "Classmate Qin Feng, can you make a bet?" "

"Huh?"

Qin Feng asked a little puzzled, "What to bet?" "

"Just bet on where you're sitting now!"

Zhu Yun pointed to Qin Feng's seat: "Qin Feng, if I win, then starting from the next math class, you must be responsible for helping me occupy a seat, which means that you can only sit in this position now!" "

After listening to Zhu Yun's request,

Qin Feng smiled speechlessly, women, really are careful eyes.

It's just that

Both the mentor and Qin Feng immediately discovered and determined that there was a problem with Zhu Yun's third solution,

She definitely can't win.

So

Qin Feng smiled and asked rhetorically, "Then what if you lose?" "

"I won't lose!"

Zhu Yun's response was very affirmative,

When the mentor heard this, he glanced at Zhu Yun with a smile and shook his head slightly.

Seeing this, other students,

Instead, they all felt uneven for Qin Feng: "Classmate Zhu Yun, what bet do you make if you only win or lose?" "

"That is, you took the initiative to ask to bet with Qin Feng, you don't even say the conditions, what else do you bet?"

"Zhu Yun, don't be too confident, Qin Feng has a full score in mathematics!"

"Good."

Hearing the rebuttals of the classmates,

Zhu Yun said confidently: "Classmate Qin Feng, if you come to mention, if I lose, I will do whatever you ask me to do." "

"Yes."

Qin Feng nodded: "If you lose, then you are responsible for helping the mentor wipe the blackboard for a month." "

"Haha, that's good."

When the mentor heard this,

Smiled happily and looked at Qin Feng and nodded.

And at this time Zhu Yun,

He also raised his chin at Qin Feng, and said extremely stubbornly: "Okay, I promise you." "

After speaking,

Zhu Yun walked up to the podium, picked up the chalk and began to calculate,

And all the students on the scene,

At this time, they all looked at the blackboard with Qin Feng and the mentor, waiting for the final result.

In the beginning,

Zhu Yun wrote quickly,

But when the problem-solving process is written one-third,

Zhu Yun stopped,

I looked back at my calculus again,

And then the face turned red,

After checking the previous calculation steps one by one,

Zhu Yun knows,

At this point where I stopped writing,

She's been wrong a lot,

It's just writing one wrong step,

This situation is exactly the same as Qin Feng said,

Zhu Yun's third solution,

Wrong from the beginning,

Just because Zhu Yun knows the detailed explanation process and correct answer to this question,

That's why it's going to be wrong.

Constantly correct the values in the process of solving the wrong problem,

In the end, I actually made a mistake and got the correct answer!

Zhu Yun knows,

I'm already wrong,

But at this time,

There are so many pairs of eyes behind him looking at him,

And

He also swore a bet with Qin Feng just now,

This is if you just put down the chalk and admit defeat,

It will definitely be mercilessly ridiculed by Qin Feng and his classmates.

So

After thinking about it for a while,

Zhu Yun stiffened,

Pick up the chalk again and continue the calculation on the blackboard...

See that Zhu Yun knows that the mistake is not corrected,

The mentor frowned slightly,

subsequently

Meeting Qin Feng's gaze, he shook his head with a helpless smile.

In many disciplines,

The requirements of mathematics are the most rigorous,

Wrong

It's just wrong.

Even if it's just a wrong symbol or a unit,

will directly affect the final result of the mathematical calculation.

Two minutes later,

Zhu Yun stopped writing again,

She went back and forth and carefully examined all her calculations.

Knowing that you have been wrong,

But Zhu Yun always felt that there was no problem with his problem-solving idea.

Biting your lip,

Zhu Yun carefully checked the whole process of the calculus again,

Finally had to accept his failure,

Then he sighed lightly,

Turn around slowly,

Bowed to the tutor and classmates and apologized: "I'm sorry, teacher, I'm sorry, Qin Feng, I'm sorry, classmates..."

"The teacher and Qin Feng are right, I was wrong from the beginning of this question, and in order to correct the calculation process, every step after me was wrong and wrong..."

Seeing that Zhu Yun woke up, he immediately bowed down to apologize to himself and his classmates,

The attitude of the instructor is quite recognized,

Nodded and said: "Student Zhu Yun, mathematics does need the research spirit of not hitting the southern wall and not looking back, but it is not wrong like you. "

"But fortunately, you still admit your mistake and apologize to me and everyone."

"In fact, as Qin Feng said, there is no problem with your idea of solving the problem, but the problem lies in the first step of your problem solving, because your first step is wrong."

The instructor turned his head to look at Qin Feng: "Qin Feng, can you use Zhu Yun's problem-solving ideas to solve this problem correctly?" "

"Yes, teacher."

Qin Feng nodded and walked slowly onto the podium,

Seeing Zhu Yun on the side standing without moving,

Qin Feng smiled and reminded, "Student Zhu Yun, it's time to wipe the blackboard!" "

"Got it."

Although Zhu Yun was still a little unconvinced by Qin Feng,

But he still obediently picked up the blackboard to wipe,

Then erase all your problem-solving process, (read violent novels, just go to Feilu Novel Network!) ）

then

Zhu Yun looked at Qin Feng, waiting for Qin Feng to write out the solution process and answer.

"Teachers, students."

Qin Feng wrote down several important data of the topic on the blackboard,

Then Langsheng said: "Although this problem solving idea of Zhu Yun is feasible, compared with the conventional method, it is actually a bit of a detour. "

"For example, this question is like going from A to point B, the regular method taught by the teacher to the students, although it is the most ordinary, but it is also the closest method and the best road conditions."

"And Zhu Yun's problem-solving idea is actually to first go from A to point C, then cross the path to point D, and then cross the river from point D to point B."

"Although this is indeed a problem-solving idea, compared with the conventional method, it has traveled a lot more and is much more troublesome."

"So, this kind of thinking can be used to show off skills, but it is not very practical."

Qin Feng said,

First write out the general problem-solving process on the blackboard,

And then

and followed Zhu Yun's train of thought and began to write Zhu Yun's problem-solving process.

In the beginning,

Zhu Yun was still unconvinced, staring at Qin Feng's every step.

But

When he saw Qin Feng writing out the problem-solving process according to his own ideas,

And after comparing with the conventional problem-solving methods taught by the teacher,

Zhu Yun was surprised to find,

It turns out that he called the third method,

In fact, it's really showing off tricks and detours,

Not only that,

While Qin Feng was still continuing his own train of thought,

Several formulas were introduced,

So that the complex problem-solving process can be directly made clear...

Looking at it,

The disobedience in Zhu Yun's heart suddenly disappeared,

Instead,

Instead, it was Qin Feng's handsome side face,

And the sunshine-filled confidence when solving problems seriously,

Inexplicably,

The roots of Zhu Yun's ears turned red,

But in the eyes that looked at Qin Feng, there were a little more unspeakable feelings...

A few minutes later,

Qin Feng wrote all the problem-solving steps,

Then he stood on the sidelines, waiting for the verification and comments of the tutor and classmates.

The instructor took the podium,

Pushed the glasses,

After carefully checking each step of the calculation process again,

He glanced at Qin Feng very appreciatively,

Then he applauded: "Classmate Qin Feng, you have a great understanding!" "

"You not only borrowed Zhu Yun's thinking to solve this problem correctly, but also used several simple formulas to directly and efficiently simplify Zhu Yun's thinking. Nice, really nice! "

At this time, the students also understood the ingenious intention of several changes in the steps of the problem,

So he followed the mentor and applauded Qin Feng one after another,

"Snap ..."

To applause,

Qin Feng smiled and thanked him, and then returned to his seat,

And Zhu Yun also followed behind Qin Feng without saying a word,

Walk towards your own seat in the back.

After the vignette,

The tutor wrote down a few more questions on the blackboard,

And carefully explain the methods and steps of solving the problem,

After another few minutes,

The end of class bell rings,

After the students watched the tutor leave,

Then he got up and left the classroom.

Played with Lu Jie and others for a while,

After sharing the beautiful scenery of summer true white,

Qin Feng got up and prepared to go to the cafeteria for lunch with Lu Jie and the others,

But when Qin Feng was about to walk to the podium,

A crisp voice stopped Qin Feng: "Classmate Qin Feng, please wait a minute." "

Qin Feng turned around,

Zhu Yun quickly walked towards Qin Feng in three steps and made two steps,

The little balls tied by the ponytail turned upside down,

The mountains under the white shirt trembled,

And the short skirt that flew up and down,

It also shows Zhu Yun's white and slender legs vividly,

Seeing Zhu Yun running towards him quickly,

Qin Feng's eyes couldn't help but light up: "I didn't expect that Zhu Yun, who looks thinner than Yu Zhouzhou, actually has a hidden secret?" "

"This bump is not smaller than Yu Zhouzhou!"

thereupon

Facing Zhu Yun,

Qin Feng smiled and asked, "Classmate Zhu Yun, is there something wrong with me?" "

"Hmm."

Zhu Yun nodded,

He looked up at Qin Feng stubbornly: "Classmate Qin Feng, I want to gamble with you again!" "

Gamble again?

This is really a big addiction!

But

Recalling the picture of Zhu Yun running towards him just now,

Qin Feng still nodded,

He smiled and asked, "Zhu Yun, what do you want to bet?" "

"Bet on programming!"

Zhu Yun immediately said,

Seeing that Qin Feng seemed a little puzzled,

He immediately explained: "Classmate Qin Feng, you are a top student in the college entrance examination and a full score in mathematics, so you are actually very good at mathematics. "

"And although I'm interested in math, I'm not as good at it as you are."

"This time, I lost because I lost to math that I wasn't good at, so I felt a little unfair."

"So, I ask to bet with you again, bet on the programming I am good at, do you dare to fight?"

"Programming?"

When Qin Feng heard this, the smile on his face was a little strange,

This morning, he only gained basic programming proficiency skills from Andy and Qu Xiaoxiu,

It was just noon, and Zhu Yun came to find himself to compare programming,

Here it comes,

What a coincidence!

Seeing that Qin Feng just smiled and did not respond for the time being,

Zhu Yun thought that Qin Feng was worried about the difficulty of programming,

So he immediately added: "Don't worry, Qin Feng, it won't be difficult, we want to compare basic programming, just programming angle and thinking, do you dare to fight?" "

Zhu Yun asked twice,

Of course Qin Feng dared,

thereupon

Qin Feng nodded directly and replied, "Okay, I'll fight." "

"But Zhu Yun, how do we bet and where do we bet? Large classrooms, dormitories, or cafeterias don't seem to fit well, and my computer is at home. "

"I'll pick a spot."

When Zhu Yun heard this, he said directly: "Qin Feng, let's add a WeChat, I will notify you after choosing a location at noon, let's start at 2 pm, is it okay?" "

"Good."

After adding Zhu Yun's WeChat,

Qin Feng walked towards the cafeteria with Lu Jie and the others,

And at this time Zhu Yun,

But turned on the group in the mobile phone, and checked the nearby hotel while walking,

Because to program the game, you need a computer.

So Zhu Yun's first choice is the e-sports hotel,

But after looking at a few esports hotels,

Zhu Yun thought again, since he was betting with Qin Feng,

Then there needs to be a blackboard in the room.

You can record the score between yourself and Qin Feng in time,

It can also write the core data of programming on the blackboard, which is convenient for recording and checking each other.

thereupon

Zhu Yun flipped several times in a row,

And then I found a hotel.

In the pictures of the rooms in this hotel,

Not only is there an indoor podium and a large blackboard,

Behind the podium, there are even two sets of tables and chairs,

The table is very large, and there are computers.

The whole looks like a microcomputer classroom in the computer department.

Zhu Yun clicked in and took a look,

This room type is a classroom theme room,

And the name of the hotel is also called the theme hotel,

thereupon

Zhu Yun directly booked the hour room from 2 to 6 o'clock in the afternoon,

Then he sent screenshots of the hotel pictures and addresses to Qin Feng,

Then also sent a WeChat,

"Classmate Qin Feng, I have already booked the hotel, and I will see you at two o'clock in the afternoon!"

... Big....
