Kuai Chuan: What to do if you madly criticize beauties who refuse to be cannon fodder

Chapter 462 Cannon fodder stepsister does not want to die (19)

The new deskmate looked at the ninth question in a hurry like an ant on a hot pot.

"Ah, it's over, I can't do the ninth question..."

Busy with the art festival, he completely forgot about the need to correct the papers in advance. Seeing that the students in front of him stood up one by one, the tablemate grabbed Jiang Lai's sleeve desperately.

"You, do you know the ninth question?"

Jiang Lai glanced at it, then took out a pen and drew an auxiliary line on her paper, followed by a formula.

As soon as I saw the auxiliary lines and formulas, the idea of ​​​​solving the problem suddenly became clear.

The new tablemate kept praying that no classmates would get stuck in front of her. Fortunately, she was lucky and everyone got through smoothly.

When she arrived, she stood up and went to the stage to draw the graphics and auxiliary lines, then listed the formula to calculate the evolution, and calculated the answer.

The class teacher looked at her with stern eyes.

"You have a clear mind now, how come you can't do it in the examination room!"

The new tablemate walked down as if he had been pardoned, the sweat on his back was slightly cold, and he looked at Jiang Lai as if he was watching his ancestors manifest, full of piety and gratitude.

Originally the first column was over and it was time to go to the first one in the second column, but the head teacher pointed at Jiang Lai directly.

"Go on, this time from the back to the front."

As soon as these words came out, all the students in this row immediately became nervous again.

The new tablemate looked at Jiang Lai nervously.

"This question is the finale of multiple-choice questions. You can just say no, and the teacher will save it for the last time."

The difficulty of the monthly exam papers is inherently high. Basically, the last question of choosing and filling in the blanks is used to widen the gap.

Moreover, the calculation amount of this question is almost the same as that of the last big question. There are seven or eight formulas involved in drawing pictures and deriving them. Most people skip this kind of question and get it later. Go back and correct the papers, and you may not be able to understand the explanations of the students in the top class.

Now that Jiang Lai was about to go on stage to explain to the whole class, everyone turned their heads to look.

This kind of question is okay, even if there is a standard answer, it may not be clear, not to mention that Jiang Lai was transferred from the art class, and everyone did not expect much from her.

The teacher looked at her, looked at the questions again, and was about to ask her to skip the fill-in-the-blank questions, when Jiang Lai stood up, picked up the paper, and walked onto the stage slowly.

all the classmates:"……"

Picking up the chalk, Jiang Lai started from the middle of the blackboard, first drew a picture, and then calculated according to the steps.

Under the stage, the two girls with the best grades in the class whispered in the front and rear seats.

"Not many people have done this question in the whole grade. Even if some people have done it, they don't know how they calculated it. Many steps don't make sense at all."

The other temper said anxiously and dissatisfied.

"Why is the teacher wasting time in class? He can just answer this question himself. Do you have to waste everyone's time listening to others read the answer for reference?"

The key reference answers are very concise, and you can't understand them after reading them.

"Maybe she asked someone in the key class for her ideas. Listen to it. Anyway, the teacher will say it again at the end."

"There are only a few people who will do this question in the key class. I have asked them all, and they all use the same method. If you want to explain it clearly, it will take at least a whole class. She probably used the method Qiao Chuwen said. , I guess it will take a lot of time.”

The homeroom teacher folded his arms and stood with his legs apart. The whole class was curious about this new student, especially the boys. The moment Jiang Lai walked into the class, many people stared straight at him. up.

In this science class where there is an extreme shortage of female resources, suddenly there is such a fair-skinned and beautiful campus figure who just shined on the stage not long ago, which boy can't help but take a peek?
Now he is on the podium, with his back to everyone, with a slender neck under the ponytail, white and slender arms raised high, and slender hands holding chalk to list formulas on the blackboard in an orderly manner, and the voice of occasional explanations is also very clear Beautiful.

The stage was silent.

Only the clacking of blackboard writing.

I thought she was going to list the entire blackboard, but after only occupying one-fifth of the positions from the beginning to the end, the answers to the questions came out.

Simple, clear, and clear, every formula used is highlighted from the beginning to the end, and the handwriting is even more pleasing to the eye, neat and clean.

Every formula is in the textbook, but every deformation method is beyond the imagination of many people.

"Damn it, can it still be like this?!"

Such an exclamation suddenly came from the audience, but no one felt it was abrupt, because it was the voice of everyone.

From start to finish, it took less than 8 minutes.

This also includes a more detailed explanation of the deformation process. If Jiang Lai did it himself, it would probably take 3 minutes.

The head teacher looked at her train of thought, then nodded, and took the lead in applauding her.

"That's right, it's very powerful! It's better than my method. Please read carefully and study carefully. How can you quickly find ideas and entry points for this type of topic!"

Jiang Lai smiled, calm and generous.

"I've done something like this before."

"You have done similar questions like this, then you have done a lot of questions."

"Learning mathematics, if you don't have talent, you can only rely on the tactics of sea of ​​questions. Thank you teacher for your compliment."

After she finished speaking, she returned to the desk, and the students in front, back, left, and left all looked at her with envy and amazement in their eyes.

The new deskmate was too excited to sit still.

God bless, why did she assign such a powerful math boss to be her deskmate!

Solitaire continues, but many people's minds are no longer on the topic.

Before the get out of class ended, the head teacher tapped the blackboard heavily.

"Some boys, pay attention to controlling your hormones, and carefully think about whether other girls can like you when you exude charm!

Jiang Lai, come to my office after class. "

As soon as Jiang Lai left, the boys in the class started discussing like a nest.

"I swear I like her when she dances!"

"Then I'll be earlier! I noticed her when she ran [-]!"

"Drink too much, what are you thinking? Why do you stay in our art class so well and come to our class? Don't you know? Don't delay people's study."

A few girls in the class are also discussing.

Although it is a science class, the two students with the best grades are still girls. They are still discussing the tenth question just now.

"I don't think it's as good as Qiao Chuwen's method. It's not about showing off your skills. Is it interesting to use all competition formulas?"

Another girl whispered.

"Qiao Chuwen's method also has a lot of competition formulas, but I didn't realize that Jiang Lai's mathematics is so good."

"Isn't it amazing that she only got over 120 in the test, why didn't I see her get a full score in the test?"

One of the girls stopped talking.

Feeling the inexplicable hostility from the other party, she sighed helplessly.
