Chapter 89 Blackboard Problem Solving
Due to the addition of two hours of evening self-study in the evening, day students have to eat dinner at school now.

Qingran separated from Ruan Ruan after dinner, and Lao Wu specially came over to explain to her today that she would go to physics class for an hour tonight.

When Qingran passed by, there were only three or five students in the physics class, and Wen Shiyi was among them.

It might be because of what happened at noon, Wen Shiyi felt a little embarrassed when she saw Qingran, she only looked up, then quickly lowered her head and continued to read, this time she didn't even say hello before.

When Qingran first arrived, he didn't know that there was someone in that position, and that position was empty.

The physics class only comes to study for an hour every day. Many students are not used to putting books in this classroom, so the desks of students who do not come are empty.

Apart from Wen Shiyi, Qingran really didn't have any familiar faces in this class. She walked into the classroom and casually asked a classmate who arrived early: "Hello classmate, is there any vacancy in this class?"

"Empty seat?" The boy who was buried in the book looked up from the book, he looked at Qingran blankly, and then stretched out his hand to push the glasses that had slipped off.

Don't know it, but pretty enough that he can try to know it right away.

The attitude of the boy with glasses became warm in an instant, he stood up, his height was about the same as Qingran's.

No wonder it was able to be in the first row.

The boy with eyes sneaked a few glances at Qingran before he said with a smile: "Oh, you are new here? There are still ten days before the physics competition, why are you here so late?"

Qingran smiled awkwardly, not knowing how to answer.

The boy with glasses is not without eyesight. He quickly realized Qingran's embarrassment, looked around the classroom, and scratched his head again: "I usually don't pay much attention to the students in the class, if there is an empty seat, I might ask... ..."

The boy with glasses paused in the middle of his words, and he looked behind Qingran in some surprise.

Qingran followed his gaze and looked back, Xie Yingan walked towards this side with long legs. When he came to Qingran's side, he glanced at the boy with glasses lightly, stretched out his hand to hold Qingran's arm and walked back.

Qingran hadn't recovered from his surprise.

Huh?Isn't Xie Ying'an not taking physics classes?For this reason, he had an unpleasant fight with Old Wu.

Only when Qingran was dragged by Xie Yingan to sit on the fifth row seat in the middle did she realize it.

"Your location?" she asked.

Xie Ying'an nodded, he didn't bring any books, and asked Qingran instead: "Why don't you ask me to come to class?"

Qingran: "..."

Who in the class doesn't know that you made such a fuss with Old Wu in order not to attend physics class?

After being stared at by Qingran for a while, Xie Ying'an seemed to remember what he did some time ago, he touched his nose in embarrassment, turned his head away and stopped looking at Qingran.

It was Wen Shiyi in front who looked back.

Qingran lowered her eyes to read the book, as if she didn't see Wen Shiyi's gaze.

I don't know if it's the plot or the fickleness of people's hearts, but she will always be a little irritating. Now her relationship with Wen Shiyi has returned to the same level as in the book, lukewarm.

The physics teacher who taught them this class quickly walked into the classroom with the lesson plan.

The physics teacher is a female teacher, about 35 years old. I heard that the principal specially invited them to teach them.

The physics teacher's eyes paused on Xie Ying'an for a while, but he didn't say anything.

She glanced at Qingran again, perhaps due to time constraints, she mentioned a sentence about the new classmate: "I heard that there is a second grader in our class, everyone welcomes the new classmate."

There was sparse applause in the classroom.

The physics teacher quickly motioned for silence, picked up the textbook and started talking about today's lesson.

There are only less than ten days left before the competition, so the physics teacher's lecture pace is very fast. After a class, the students are almost memorizing the summary points.

Qingran didn't find it difficult to study, and she had been able to get good grades in the exams for so many years, she relied entirely on her real talents and practical learning.

Towards the end, the physics teacher wrote two physics questions on the blackboard, one on the left and one on the right. She looked around the classroom, probably entering the questioning session.

"Student Wen Shiyi," the physics teacher looked at Wen Shiyi, and she pointed to the question on the right: "You do this question."

"Okay, teacher."

Wen Shiyi stood up and walked to the podium, took a piece of chalk and started to solve the problem on the right.

"The question on the left, new student..." The physics teacher smiled at Qingran, "I'm sorry, I haven't been able to remember your name yet."

Qingran stood up from her seat and introduced herself: "Hello, teacher, my name is Li Qingran."

"Hi, Li Qingran." The physics teacher nodded in satisfaction, and she pointed to the problem on the blackboard on the left: "You do this problem."

On the same podium as the heroine, do questions from left to right?

To tell the truth, Qingran had no idea.

She also knew that this was the physics teacher's understanding of her. After all, before the midterm exam this year, her grades had not been very good.

But the heroine also has a halo, she was close to Xie Ying'an that day, the heroine's aura is not better than the hero's halo, if you wait to do the question, you are so close to the heroine, and so far away from the hero...

Qingran's heart was even more uncertain, but now she had no choice but to act. In desperation, she reached under the table and grabbed Xie Ying'an's hand.

In a trance, Qingran had the illusion that the hand she was holding seemed to have been waiting for her for a long time, and she was tightly grasped as soon as she stretched it out.

It seemed that the young man's extremely light and joyful laughter could be heard in his ears.

After more than ten seconds, Qingran let go of Xie Yingan's hand and strode towards the podium.

During this period, she didn't dare to look at Xie Ying'an's expression the whole time.

Due to the rush of equipment in the new classrooms, even the multimedia has not been implanted in time, and the old blackboards are still the same as when the school was founded.

The two questions written by the physics teacher were not simple, and Wen Shiyi's steps to solve the questions on the right had almost filled half of the blackboard on the right.

When she got to the podium, Qingran's emotions had calmed down. She picked up the chalk from the podium and looked at the question again. There was a vague impression of this question in her mind, and she began to answer it.

The girl had a clear mind, and the steps to solve the problem were concise and precise. She was several minutes later than Wen Shiyi, but the two of them finished the problem together.

The students in this class all had some grades in physics, and they were shocked by Qingran's problem-solving ideas for a while.

There was a muffled discussion below.

The chalk was put back into the chalk box, Wen Shiyi walked through the aisle on the right, and Qingran walked through the aisle on the left.

Back on the seat, the embarrassing thing for Qingran did not happen, Xie Yingan looked up at the problem she solved on the blackboard thoughtfully.

There are two questions on the left and right on the blackboard. The idea of ​​solving the questions on the left is simplified to the extreme, but the steps are calculated at a glance, and there is a sense of sudden enlightenment.

It turns out that the solution to this problem can be simplified to this!
The solution to the question on the right is more complicated than the question on the left. Wen Shiyi applied several formulas, which can be said to be quite satisfactory.

If there is no comparison, Wen Shiyi's question alone will undoubtedly make people unable to pick out the problem from the perspective of problem-solving ideas.

However, Qingran's concise problem-solving ideas came first, while Wen Shiyi's problem-solving ideas seemed too complicated no matter how you looked at it.

The physics teacher also looked at Qingran's problem-solving ideas, and it took a long time to turn her head to face her classmates. She smiled and looked at Qingran with admiration in her eyes.

"Like Li Qingran's slanted way of solving problems," she paused, and then said slowly: "A few years ago, I only saw it at a math genius in F high."
