Chapter 429

The math teacher originally wanted to use this topic to admonish the little girl, but now she found that Su Qinghuan really made great progress!

Seeing Su Qinghuan walking calmly down the platform, as if she didn't take the problem seriously, the math teacher looked at her again with a little complexity.

That look is hard to describe.

As a learning scum, yanziche under the podium misunderstood the meaning of the math teacher on the spot, and he just laughed.

"Teacher, is Su Qinghuan all wrong? Otherwise, why do you look so dignified?"

“……”

The math teacher shook his head a little embarrassed.

He can't afford to offend the two brothers of Yan family, otherwise he really wants to shut up the dead boy.

The math teacher coughed on the platform.

"The answer to this question... In fact..."

But just then, a lazy voice sounded.

"Su Qinghuan is right."

It was Fu Siling who was robbing the math teacher's lines.

The crowd looked at Fu Siling in surprise.

Obviously, I didn't expect that Fu Siling, as a Xueba, would help Su Qinghuan here.

Su Qinghuan also looked at Fu Siling in surprise. She saw something of reward in the man's eyes.

Fu Siling raised his eyebrows at Su Qinghuan.

"Why, I calculated the same answer as you. Isn't it worth being happy?"

Su Qinghuan felt a chill when she heard Fu Siling's words of narcissism.

"... no, no, no, you shouldn't say I have the same answer as you. I just want to be the same as the standard answer."

As for Fu Siling, it doesn't matter what she does.

……

She would never be proud to be the same as Fu Siling or the second.

Since her name is Su Qinghuan, she should be proud to be su Qinghuan first.

People are like this.

Instead of chasing the aura of others, it's better to open up your own world. The accumulation of glory is far more pleasant than anything else in the world.

……

When Ji ran saw Su Qinghuan's face falling on Fu Siling like this, the boy suddenly frowned and looked at Fu Siling with some teasing.

"Yes, only the standard answer is the most important. Who wants to be the same as Fu?"

"You --"

Fu Siling was so angry that his eyes were heavy.

But Ji ran was already very familiar with hooking Su Qinghuan's arm.

"Su Su, you're great. Can you teach me how to make this answer?"

Su Qinghuan looked helplessly and connivantly at Ji ran.

She found that she couldn't lose her temper with Ji ran, especially when Ji ran was coquettish and close to herself, she couldn't refuse each other.

"Listen to the teacher first. If you don't understand, I'll teach you after class."

"OK."

……

Seeing that Ji ran approached Su Qinghuan with such a clumsy means, Fu Siling was a little bored and anxious.

Ji ran, who plays the role of a pig and eats a tiger, can she really be baffled by such a math problem, even if it is a little difficult?

Fu Siling was very upset.

The math teacher on the stage has motioned everyone to be quiet and explain the practice of this problem.

"Students, be quiet. Let's look at the problem-solving process of Su Qinghuan. She uses the method of geometric proof and adds auxiliary lines. Please look at this key place..."

……

The steps the teacher said were very detailed, much more detailed than Su Qinghuan's answer.

Su Qinghuan was about to ask Ji ran if he didn't understand anything.

However, when I turned around, I saw that Ji ran was staring at herself, and the corners of the beauty's lips rose. It seemed that the eyes hidden by the stars were glowing.

"... listen carefully!"

Su Qinghuan was helpless. If Ji ran hadn't been beautiful and white, she almost wanted to reward this learning residue with a fried chestnut.

The college entrance examination will be held in a month.

Why not listen carefully?

……

"Well, well, listen to Su Su."

“……”

What does this have to do with listening to her?

Su Qinghuan lost another second.

But Ji ran turned his head and looked on the blackboard.

Su Qinghuan was praised.

Whether you understand it or not, at least show your attitude.

If you don't even have this learning attitude, what about extra points in the college entrance examination?

……

Su Qinghuan was feeling, but he saw a piece of paper floating down.

That's Ji Ran's draft paper.

Because the paper floated on Su Qinghuan's side, Su Qinghuan subconsciously picked it up.

"Don't move. Pick it up after class."

But Ji Ran's eyes showed a different color and almost stopped it without thinking.

Su Qinghuan mistakenly thought it was the other party's thin skin. She smiled calmly.

"It's okay. I'll just help you."

Anyway, these high school knowledge is not much different from her previous studies. Su Qinghuan doesn't think he has to listen so attentively.

Su Qinghuan picked up the draft paper.

But I saw a line drawn on the manuscript paper.

It is the auxiliary line added by Su Qinghuan on the blackboard.

If Ji ran copied and pasted her answers on the blackboard, Su Qinghuan also believed it.

But what changed Su Qinghuan's appearance was another thing.

Because Ji ran also wrote a simple equation on the draft paper.

This formula is sketchy, omits many key steps, and does not substitute the problem to write the real solution process.

But Su Qinghuan understood that the equation was another solution to the problem. Only by establishing a rectangular coordinate system can this formula be applied.

However, there was no rectangular coordinate system drawn by Ji ran on the draft paper.

Moreover, this equation is impossible for ordinary people to think of leapfrog thinking.

Unless... Ji Ran's mind has already automatically substituted specific painting methods.

Using the knowledge of geometric proof, it is actually easier to understand this problem, but it is faster to use rectangular coordinate system if it can be formulated reasonably.

The two methods have their own advantages.

……

Su Qinghuan's thin lips pursed slightly, and there was a feeling in his heart that he couldn't say anything.

She is a clever person by nature.

At the moment, seeing Ji Ran's slightly cramped expression, he was even more suspicious.

"You can do this problem, can't you?"

"Su Su, what are you talking about? I don't understand."

Ji ran looks innocent.

"Didn't you write the formula above?"

"Ah? I wrote it casually."

Ji ran can't use this reason. After all, he didn't substitute the specific data of that topic at all.

Unfortunately, Su Qinghuan is also a calculation expert. Even if she didn't choose the second method at that time, it doesn't mean she can't calculate quickly in her brain.

"Forget it."

Su Qinghuan happily returns the draft paper to Ji ran.

In fact, Ji Ran's good math is also a good thing, but she's just unhappy. Ji ran plays a pig and eats a tiger or is bored. Why tease her?

Fortunately, she really wanted to take Ji Ran's college entrance examination.

……

Originally, Ji ran had a little luck in his heart. Seeing Su Qinghuan's reaction, he immediately regretted that he shouldn't have owed his hand at that time.
