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

Cm>n>p

Dn>p>m

Xu Heng looked at Yang Kaixuan's train of thought.

According to the meaning of the question, m>0, n>0, p>0,

because……

……

I have written a lot and are under the root sign, and I am doing various calculations, which makes me feel dizzy.

And the whole problem-solving process took up a whole page of paper.

It doesn't take five or six minutes. This multiple-choice question cannot be done!

Xu Heng shook his head, "It's a waste of time! Let's put it this way, here is a basic common sense, π is 3.14, then lnπ is 1.14, you should know this, right?"

Yang Kaixuan shook his head blankly.

Xu Heng looked at him and understood.

"Okay... Anyway, you just need to remember it in the future, so choose D for this question, and you're done."

Not even 1 minute!

Even for a few seconds!

Yang Kaixuan was still in a daze and didn't recover for a while.

Xu Heng returned the question to Yang Kaixuan, picked up his phone, put on his earphones, and started playing.

Only then did Yang Kaixuan come back to his senses, "Hiss..."

Xu Heng never let him down.

No matter what type of question it is, Xu Heng can always give different and simpler solutions.

A night without dreams.

"Ring Ling Ling..."

Yue Pingting called Xu Heng and told Xu Heng to get up.

After Xu Heng washed up, he just left the door of the dormitory...

In the past, Yue Pingting herself was waiting for him, but today, the principal is also there.

Although the principal asked Xu Heng to think more and think for himself, it didn't stop him from coming to Xu Heng to show his courtesy.

Xu Heng, "Uh..."

Yue Pingting was also very strange, but she didn't ask why.

Between her and the principal, she is still in awe of the principal!

It wasn't until Xu Heng appeared that Yue Pingting approached Xu Heng and asked, "What's the matter? The principal came here earlier than me."

Xu Heng, "The principal asked me to teach the teachers."

Yue Pingting, "What did you say...? I didn't catch it, you said...?"

Xu Heng, "Let me teach the whole school teachers."

Yue Pingting was startled, and turned her gaze to the principal, "Principal, what do you think! Really...really?"

The headmaster nodded, "Yes!"

Yue Pingting, "Hiss...!"

The principal looked at Xu Heng with a smile on his face.

"Student Xu Heng, don't worry, the teachers in our school admire you very much!"

"Ms. Yao is too, Mr. Xue is too, and Mr. Qin is even more..."

"so……"

Xu Heng, "Stop it! Stop it! Principal, can I agree? Just tonight! Alright! After the evening self-study starts, I will go!"

The principal was overjoyed, "Okay! Thank you, Xu Heng!"

Xu Heng, "Then can we have breakfast alone?"

Principal, "Yes, yes! Sorry, I won't bother you!"

The principal, the big light bulb, slipped away.

Xu Heng, "%￥#@#%%..."

"Hey……"

Sighing, Xu Heng and Yue Pingting had breakfast together.

Yue Pingting, "Seeing your frown, I don't know what to say?"

"Hiss... If it were me, I think I would be so nervous... After all, it's the teachers of the whole school!"

"They were originally here to teach us, but now they ask you to teach them."

"The headmaster really thought of it, it's a one-off!"

Xu Heng looked at Yue Pingting and asked, "Are you trying to defend me?"

Yue Pingting pinched her waist, "Yes!"

Xu Heng, "Hahaha... okay, okay, I'm not thinking about what to say, I'm thinking about something else."

Yue Pingting, "For example?"

Xu Heng, "Eat your breakfast!"

Xu Heng's concern is, if he speaks well, will there be another time?

So this is a very headache!

In other words, there is no second time.

But... those teachers all come to ask him for advice, what should he do when the time comes?

It's not that Xu Heng has confidence in himself, but the fact is like this!

Kevin is the perfect example!

The former Yao Ruiyi and Qin Fangming are the best examples!

"hiss……!"

Xu Heng frowned, thinking, he had to avoid problems and start with learning methods and methods. After all, they are teachers, so they are better at these things.

……

night.

Evening study.

Xu Heng arrived at the conference room on time.

Large conference room.

All the teachers are here!

They looked at Xu Heng one by one, with expectation in their eyes.

Every teacher is like this!

They didn't have any doubts about Xu Heng.

In front of everyone, there is a notebook.

They are very exaggerated. Some teachers have already picked up their pens and are ready to take notes.

Xu Heng smiled, "Hi, teachers!"

Everyone, "Mr. Xu Heng is good!"

puff-

Being called a teacher by a group of teachers is really uncomfortable.

Xu Heng was invited by the principal to take the first seat at the conference table!

This used to be the headmaster's position!

If the vice-principal presided over the meeting, even if the principal wasn't there, he wouldn't be able to take this seat, but Xu Heng could!

And it was the headmaster who personally brought Xu Heng to sit here.

"Sit and sit!"

"Let's not make some high-sounding words! Time is running out! Hurry up, everyone!"

The principal smiled at Xu Heng, "Student Xu Heng,... Oh! No! Teacher Xu Heng, please start..."

Xu Heng took a deep breath, looked at all the teachers present on the stage, and said slowly, "Every teacher..."

"..."

Xu Heng starts with the way of learning.

How much he said!

He saw that there was a teacher recording from the beginning to the end of his lecture.

Xu Heng, "%￥#@#￥%..."

teacher!

You are not a recorder!

You remember everything so well!

"hiss……"

With the end of the first class evening self-study, Xu Heng also finished speaking.

He was silent.

headmaster,"???"

Teachers, "???"

Everyone pricked up their ears, waiting earnestly, wanting to listen earnestly.

Can……

Xu Heng stopped talking, and it was over.

Everyone, look at me, and I look at you.

Principal, "Student Xu Heng, you..."

Xu Heng, "It's over, I'm done, principal!"

The principal, "Huh? Just, just, is it over?"

"I, I thought you would talk until 9:[-], until school was over!"

Xu Heng, "No no no! One class is enough! More than enough!"

"My mission is complete! Teachers, think about it for yourself!"

"I won't bother you anymore, I'll go first, bye!"

Get away!

The soles of Xu Heng's feet seemed to be oiled, and when he stabbed them, he disappeared.

Dear teachers, you look at me, I look at you.

"hiss……"

"Although he only spoke for 45 minutes, what Xu Heng said made sense. He is not dealing with us!"

The principal also gasped, "That's true...Although he said it so lightly and said that the task is not a task, he is so serious in doing things!"
