Chapter 79

"OK, now that we all understand this question, let's go to question 5."

Cheng Nuo's eyes in the class around a week, light smile said.

"Come on, students who are right in question 5, please raise your little hands!"

More than 30 people in the class raised their hands reluctantly.

"Well, Jiang Qingqing, since you have done the right thing, let's talk about your solution steps."

…………

After a few questions, Cheng Nuo completely repeated the previous steps.

First ask the right person to raise their hands, and then choose one of them to talk about the steps. And then very kind to ask if there is not understood.

If there is one? Good! After class directly find the topic of the students to ask once on the line!

The mood of the whole class now is really lying trough!

Your sister, Lao Tang asked you to replace the class so that you could give us a lecture.

But you're good! Except let's raise our hands and call the roll. It's nothing. The topic is amazing. We did it all!

You say, we want you to be a substitute teacher, what's the use!!

What did you say before? If you can do it, you can't, don't beep!

Can really according to Cheng Nuo this play method, say a word of truth, I really can go up!

In a burst of complaints from the whole class. Cheng Nuo got to the last question.

"Come on, raise your hand if you are right in question 21." Cheng Nuo asked.

Silence No one raised their hands.

But it's really not the whole class who is deliberately against Cheng Nuo. It's really No one is right!

To be exact, except Cheng Nuo, there are 50 students in the class, and no one else has done the last question completely.

Looking at the scene in front of no one to raise his hand, Cheng Nuo is indeed some wax.

So he looked at Mu Leng and said, "Muran, you..."

"Don't look at me. I didn't do it right." Mu Leng turned his eyes and didn't give Cheng Nuo face at all.

Cheng Nuo is stunned, and the air is filled with a faint atmosphere of embarrassment.

"Cough." Cheng Nuo coughed a few times and walked up to the platform. With a long sigh, "Oh. There's no way. I wanted to hide it, but in the end, I still need to show up! "

"Students, please open your eyes, do not blink, to see how I can easily solve this problem in a few steps." Cheng Nuo picked up a piece of chalk and said.

The students were speechless for a while, but they were also very curious whether Cheng Nuo could explain the problem clearly.

It's not a skill to do it. It's the ability to make it clear to someone who can't!

The last one is about elliptic functions. The title is not difficult in all the final questions, but it is not simple. It is even more difficult to do the right thing.

Cheng Nuo lists the graphs and known conditions on the blackboard. Then I found an open space on the blackboard. I wrote on the blackboard and explained it to the students.

"The first question is very simple. Let's ask the elliptic equation. Let's see what is known and what is unknown in the elliptic formula, and then..."

Well, in just two or three minutes, Cheng Nuo explained this problem clearly. Under the platform, the students also nodded secretly, indicating that they had understood.

But unexpectedly, Cheng Nuo threw away the chalk which only had a head, picked up a new one from the chalk box, turned around and wrote a big "two" on the blackboard!

"Now, let me tell you about the second solution to this problem."

No The second solution!

After listening to Cheng Nuo's words, the students can't help but grow up with astonished mouths.

There's a second solution?!

Cheng Nuo can ignore the eyes of people's consternation, while speaking and writing.

By the end of the second solution, the whole blackboard has been completely filled by Cheng Nuo.

Cheng Nuo wiped out the left half of the blackboard filled with the first solution, and then wrote a "three" on the top.

No way!! There's a third solution!

People feel numb. For them, to come up with a solution is already the existence of Xueba level.

Can Cheng Nuo pour good, come up with three kinds of solution all at once! It's just So terrible!

"Let's look at the third solution." Cheng Nuo faintly smiles, Shua Shua Shua Shua writes the third solution on the blackboard.

And at this time, the bell rang right after class.

"Well, that's all for today's class." Cheng Nuo threw the chalk on the stage, knocked on the blackboard with one hand and said, "in fact, I have come up with five solutions to this problem. Due to time, I can only tell you three. If you are interested, you can ask me after class! "

"Well, that's all for today. Class is over!"

We are still shocked by Cheng Nuo's five solutions. So after hearing Cheng Nuo's "class over", almost all the students in the class stood up and called out in an orderly way, except for a few people."Goodbye, teacher!"

In an instant, everyone's face turned black again!

……………

"The sun is bright, the rain in the West! I don't know when my sister's sweetheart will be back! "

After school in the evening, Cheng Nuo, who is in a good mood, rides his bicycle all the way and hums a tune into Zhuyuan community.

When Cheng Nuo passes the second floor, he is relieved to see that Fang Lian's house is locked.

Thinking of that delicate brooch, Cheng Nuo is heartbroken again

The mouth is cheap, is the mouth cheap causes the disaster!

Thinking like this, Cheng Nuo walked into the house.

But just pushed the door in, Cheng Nuo felt that there was something wrong with the atmosphere at home.

"Still no clue?" Cheng Nuo, who changes shoes at the door, hears his father sigh and says.

"Don't say it. It's like Xiao Nuo is back." Jiang LAN whispered softly.

The two immediately stopped discussing.

Cheng Nuo's eyebrows slightly wrinkled, carrying a schoolbag into the living room.

"Xiao Nuo, come back!" Jiang Lan's mouth barely squeezed out a smile. "Come on, sit down first. I'll get you a glass of milk."

Jiang LAN gets up and walks to the kitchen. Soon, with a glass of milk in front of Cheng Nuo.

"Thank you, mom!"

Cheng Nuo said thanks and drank the whole glass of milk in one breath.

Because Cheng Yuanjin and Jiang LAN are worried, they are not in the mood to speak. The atmosphere in the whole living room fell into a kind of strange dullness.

There was only one TV set, which was broadcasting the evening news.

Cheng Nuo is also very puzzled, what is the matter, let two people show such a sad look.

Cheng Nuo couldn't help asking, "Mom, is something going on?"

Jiang LAN reluctantly smile, "it's OK, you still have homework to do, go back to your room and hurry to do it."

Obviously, Jiang LAN didn't tell Cheng Nuo the plan.

Cheng Yuanjin also helped, "it's really nothing. Even if there's something wrong, we can solve it! "

Cheng Nuo sighs. When he is ready to get up and go back to his room, a news broadcast on the TV attracts Cheng Nuo.

"Here's a message. At 7 o'clock this morning, Qingcheng bank located in Minjiang branch road was robbed... "
