Chapter 534

Xi Ying took a look at the blackboard.

This is the third question of a geometric proof.

This kind of topic usually appears in the last few big questions.

And the third small question of the last few big questions, the students basically will not answer.

Because it's too hard and takes too much time.

The math teacher obviously embarrassed Xi Ying because he just wanted to talk about how to solve the problem.

He wanted to let Xi Ying know that the classroom is very important now. She is the one who wants to sprint for the college entrance examination. She can't be so muddled down any more!

However, Xi Ying stood up from her position, went to the blackboard, picked up a piece of chalk and began to write.

It is not the first time that Yuan Bai has been on the blackboard.

But today's yuan Bai's handwriting is quite different from before.

In the past, I always felt that there was a small family spirit, but now, the dragon and Phoenix are dancing, and they are rebellious and free and easy, and they also carry a murderous spirit of bullying people.

It took Xi Ying five minutes to write a blackboard.

The first reason is that there are many necessary steps to prove the geometry problem, and the second reason is that her font is too bold, so it occupies the whole blackboard.

The math teacher was stunned.

It's not because Xi Ying can solve this problem, nor is she shocked by her sudden change of handwriting, but because!!

This kind of problem-solving method, is graduate students will do ah!

It uses a lot of formulas that can't even be learned in college mathematics.

This

The math teacher looked at Xi Ying strangely.

Yuan Bai, who has always been able to pass mathematics, suddenly put so much knowledge in his head?

And it works?

"Can I go out? Teacher. " Xi Ying fulfilled her duty as a student and asked politely.

"You What are you doing out there The attitude of the math teacher changed all of a sudden.

Although he didn't understand what made yuan Bai suddenly become like this, he was honored to have such a talented student!

"Go around."

Xi Ying's answer made the math teacher's mouth twitch.

During the class to the teacher said to go out for a stroll, it is estimated that Yuan Bai is a wonderful flower.

So do the students.

But something even more extraordinary happened.

"You go."

The math teacher agreed!

"Thank you, teacher." Xi Ying walks out of the classroom.

The math teacher looked at Xi Ying's back and wiped the sweat from his forehead.

Can't you agree.

Yuan Bai's way of thinking in solving this problem is much clearer and more flexible than he is. Giving lectures in front of Yuan Bai gives him a sense of being a dagger in front of Guan Gong.

It's better to let yuan Bai out.

The reason why Xi Ying came up with the idea was to look at the structure of the school so that he could escape when the end of the world broke out.

She doesn't know what the mission of God is, so she can't leave school for the time being.

If the task is to ask her to protect someone in the school.

It's class time now. There are basically no people outside the teaching building.

Xi Ying walked around the whole school.

When we came to the experimental building, we found a boy in the small garden behind the building.

The boy squatted on the ground with his back to her, not knowing what he was doing.

Xi Ying walks over.

She keeps a tentative attitude towards every male who appears in her sight.

The seat tassels wear leather shoes, and the sound of contact with the ground is not small.

But the teenager didn't react at all.

Xi Ying took a closer look.

The boy was dissecting a frog.
