Chen Jialin's grades are actually only at the level of sixty or seventy points, which is definitely in the middle and lower reaches of other schools, but in Blue Sky No. 3 Middle School, it is the first in the proper grade.

The first in this grade also made her mother very proud in front of that woman......

Everyone doesn't know that although at school, she always plays with everyone, but in fact, when she comes home at night, she has to stay up late every day to stay up until the early hours of the morning, just to keep the first place in this grade.

Although Chen Jialin didn't seem to care about it on the surface at this time, in fact, she kept looking at the topic on the blackboard.

Damn it...... She couldn't even understand the title......

This Luo Xingcen must have deliberately found a question that he couldn't understand and took it out to show off!

Luo Xingcen listened to all the words that these students were talking about, but she didn't care at all.

She quickly copied the problem on the blackboard, turned around and said to Teacher Li respectfully: "Teacher Li, I don't mean anything else, it's just that my mathematical foundation is not very good, and I really don't have any ideas for this problem, can you tell me about it?" ”

Teacher Li was still staring at Luo Xingcen with a wary expression.

His three-year contract was about to expire, and he was going to escape from the den of thieves when the next semester started...... I don't want to lose my chances!

It's just that Mr. Li couldn't help but peek at the question on the blackboard.

The short three lines of chalk on the blackboard seem a little abrupt, but the handwriting is very neat and beautiful, and then look at the content......

What a math problem!

This question is not beyond the outline, but the angle of the question is relatively special, and several knowledge points need to be synthesized......

Could it be that this student is really here to ask the problem?

Teacher Li's heart suddenly had mixed feelings, "This classmate, what do you think of this question?" ”

Luo Xingcen looked at Mr. Li and replied seriously: "Mr. Li, the first question in this question is to find the coefficients of the inverse proportional function, through the known conditions, you can get k = 1 by substituting the inverse proportional analytic formula, but then I have no clue about finding the intersection of the inverse proportional function and the intersection of the straight line, and finally finding the coordinates of the M point in the future." ”

Teacher Li listened to Luo Xingcen's words, and his heart moved.

This student is not playing tricks on him......

Even if it really is, he asked her to spend so much effort to do the problem in order to trick him, as a teacher, he felt that it was worth it.

Teacher Li glanced at the noisy classmates below with a complicated expression, and no longer hesitated.

He picked up a piece of chalk and began to explain while drawing, "This problem is a comprehensive application problem, you look at this condition, the key to this problem is actually to determine the analytic formula of the function through the method of undetermined coefficients, and then ......"

The more the teacher and student on the podium communicated, the more energetic they became, and Mr. Li was still a little restrained at first, but as Luo Xingcen asked one question after another, he became more and more excited.

Preach, teach, and dispel doubts!

This is the vow he made when he decided to become a people's teacher, and now, he is finally practicing the mission of a teacher again!

Liu Tingting didn't know when, she also walked on the podium, she also had a lot of things she didn't understand, so she seized the opportunity to ask.

The two were pleasantly surprised to find that Mr. Li was actually very powerful.

The topics will be explained in simple terms, and they will be guided to draw inferences from each other and give them how to connect the knowledge points.

The students below quieted down at some point, and the atmosphere was solemn and depressing.

Suddenly, a boy stood up and yelled, "Hey, what are you two pretending to be!" To learn TMD to get out of here! ”
