Chapter 81: Let me go to me too!

　　 "Okay, since everyone understands this question, let's look at question 5 next."
　　 Cheng Nuo looked around the class for a week, and said with a faint smile.
　　 "Come on, students who did the 5th question right, please raise your little hands!"
　　 More than 30 people in the class raised their hands reluctantly.
　　 "Well, Jiang Qingqing, since you got it right, then tell everyone about your problem-solving steps."
　　…………
After 　　 several questions, Cheng Nuo completely repeated the previous steps.
　　 Let the person who did the right raise his hand, and then pick one from the inside to explain the problem-solving steps. Then I asked very kindly if I did not understand.
　　 Any words? well! Just ask the classmate who is talking about the topic directly after class!
　　The mood of the whole class is really stubborn!
　　Your sister, Tang asked you to substitute for the lesson so that you could teach us the topic.
　　 But good for you! Except for letting us raise our hands and then click our names. It's nothing. We do all the talk about the magic horse!
　　 You said, what use do we want you as a substitute teacher! !
　　 What I said before. If you can do it, you can do it, don’t beep!
　　 can really follow Cheng Nuo's gameplay, to be honest, I can really go!
　　 in the whole class's complaints. Cheng Nuo came to the last question.
　　 "Come on, the student who did the correct question 21 raise his hand." Cheng Nuo asked.
　　 Silence... No one raised their hands.
　　 But it's really not that the whole class deliberately went against Cheng Nuo. But indeed... no one is doing it right!
　　 To be precise, apart from Cheng Nuo, there are fifty people in the class, and no one else has done the last question completely.
　　 Seeing the scene where no one raised their hands in front of him, Cheng Nuo was indeed sitting on wax.
　　 So he looked at Muleng for help, "Muleng, you..."
　　 "Don't look at me, I didn't do it right." Mu Leng rolled his eyes vigorously, not giving Cheng Nuo any face.
　　 Cheng Nuo was startled, a touch of embarrassment filled the air.
　　 "Cough cough." Cheng Nuo coughed a few times and strode up to the podium. With a long sigh, "Oh. There is no way, I wanted to hide it, but I didn't expect that in the end, I still need to appear!"
　　 "Students, please keep your eyes open, don't blink, and see how the teacher can solve this problem in a few easy steps." Cheng Nuo picked up a piece of chalk and said.
　　 The classmates were speechless for a while, but it was also very curious whether Cheng Nuo could explain this question clearly.
　　 It’s not a skill to do it. It’s a skill to explain a person who doesn’t know how to do it!
　　 The last question is about elliptic function. The title is not difficult among all the final questions, but it is not easy. It is even more difficult to do it right without losing a point.
　　 Cheng Nuo listed the graphs and known conditions on the blackboard. Then I found an open space on the blackboard and leaned sideways to explain to the students while writing eloquently.
　　 "The first question is very simple. To ask for an ellipse equation, just look at those in the ellipse formula that are known and which are unknown, and then..."
　　 Let it go, in just two or three minutes, Cheng Nuo explained this question clearly. The students under the stage also nodded secretly, indicating that they had understood.
　　Unexpectedly, Cheng Nuo threw away the chalk with only one head left, picked up a new one from the chalk box, turned his head and wrote a big "two" on the blackboard!
　　 "Next, let me tell everyone about the second solution to this problem."
　　第...The second solution!
　　 After listening to Cheng Nuo's words, the classmates couldn't help but grow their mouths of surprise.
　　 There is a second solution? !
　　 Cheng Nuo ignored the horrified eyes of everyone, and wrote while speaking.
　　 When the second solution is finished, the entire blackboard has been completely written by Cheng Nuo.
　　 I saw Cheng Nuo erase the left half of the blackboard filled with the first solution, and then write a "three" on the top.
No way! ! There is a third solution!
　　 Everyone felt numb. For them, if they can come up with a solution, they are already at the level of academic masters.
　　 Cheng Nuo is good, and I came up with three solutions at once! It's... horrible!
　　 "Let's see the third solution below." Cheng Nuo smiled faintly, and wrote the third solution on the blackboard.
　　 At this time, the bell rang after class.
"Okay, that's all for today's class." Cheng Nuo dropped the chalk on the podium, tapping on the blackboard with one hand and said, "Actually, I have come up with five solutions to this question. I can tell you three. If you are interested, you can ask me after class!"
　　 "Well, I'll be here today, get out of class is over!"
　　Everyone is still shocked by the five solutions Cheng Nuo said. So when they heard Cheng Nuo's "Class end", except for a few people, almost all the people in the class stood up reflexively and shouted neatly.
"goodbye teacher!"
　　In an instant, everyone turned black again!
　　………………
　　 "The sun is bright, the rain from the west! I don't know the sweetheart of my sister, when will you come back!..."
　　 After school in the evening, Cheng Nuo, who was in a good mood, rode his bicycle all the way, humming and walked into the Zhuyuan community.
　　 When Cheng Nuo passed by the second floor, he could not help but breathe a sigh of relief when he saw Fang Lian's door locked.
　　 Thinking of that delicate brooch, Cheng Nuo was heartbroken again...
　　 Cheap mouth, UU reading www.uukanshu.com is the fault of cheap mouth!
　　 Thinking like this in his heart, Cheng Nuo walked into the house.
　　 But as soon as he opened the door to enter, Cheng Nuo felt that the atmosphere at home was a bit wrong.
　　 "Is there still no clue?" Cheng Nuo, who was changing shoes at the door, heard his father sigh and said.
　　 "Stop talking, it seems that Xiao Nuo is back." Jiang Lan whispered softly.
　　 The two immediately stopped discussing.
　　 Cheng Nuo frowned slightly and walked into the living room with his schoolbag.
　　 "Xiao Nuo, you are back!" Jiang Lan barely forced a smile from the corner of her mouth. "Come on, sit down first, I'll get you a glass of milk."
　　 Jiang Lan got up and walked to the kitchen. Soon, holding a glass of milk in front of Cheng Nuo.
　　 "Thank you mom!"
　　 Cheng Nuo thanked him and drank the whole glass of milk in one breath.
　　 Since Cheng Yuanjin and Jiang Lan are both worried, they are not in the mood to speak. The atmosphere in the entire living room fell into a strange dullness.
　　 There is only one TV set, which is broadcasting the evening news.
　　 Cheng Nuo was also wondering what it was that made the two of them look so sad.
　　 Cheng Nuo couldn't help but asked, "Mom, did something happen?"
　　 Jiang Lan smiled reluctantly, "It's okay, don't you still have homework to do? Go back to your room and do it."
　　 Obviously, Jiang Lan didn't tell Cheng Nuo the plan.
　　 Cheng Yuanjin also helped out, "It's really nothing. Even if something happens, we two will solve it!"
　　 Cheng Nuo sighed. Just as he was about to get up and go back to the room, a news broadcast on the TV attracted Cheng Nuo.
　　 "The following is an announcement. At 7 o'clock this morning, Qingcheng Bank on Minjiang Branch Road was robbed..."
