But except for the physics teacher and Luo Liyan, everyone looked at him with a blank face.
The difficulty of this question can be considered in the final extra points of the first year of high school physics, but if you use the knowledge of junior physics majors to solve it, you only need a formula.
And Le Bainan used the knowledge from his junior year.
The physics teacher thought about it for a while at first, and then realized this knowledge point. The whole person stayed there, swallowed after more than a minute, and then laughed a little awkwardly.
"Student Le's solution is also correct, but this knowledge point is not a learning point in the first year of high school, so let me solve it."
After finishing speaking, he rewrote the problem-solving steps after Le Bainan's writing on the blackboard.
There are 8 lines in total, which seems particularly troublesome, but it can be understood by all the students in the class.
Luo Liyan said to Le Bainan in a low voice: "Did you see that what the teacher wrote is what I learned."
He wrote so naively.
Le Bonan thought in his heart.
He understood those knowledge points when he was six years old.
He couldn't figure out what was the point of Yanyan spending so much time every day just to learn such a simple thing.
But when he thought of the test paper scores he saw, he didn't dare to really say the thoughts that flashed through his mind.
His intuition told him that if he really said that, it might make Yanyan unhappy.
He dare not.
"Okay, I will use this next time." Le Bainan said seriously.
Physics, using what he learned at the age of six to teach Yanyan.
For others, see.
Probably about the same.
Having made up their minds, the two of them re-entered, read a book for a while, and smiled at each other.
After a class, Le Bainan wanted to go to the bathroom, Luo Liyan naturally worriedly dragged Le Xueqin to accompany him.
Just standing outside the door of the men's toilet, Le Xueqin looked at the boys who came in and out, all looking at them playfully.
"Sister-in-law, this is the first time I have accompanied a boy to the bathroom." Le Xueqin felt a little strange.
It's not resistance, it's really never experienced.
Didn't even look at it.
After all, there are many girls and girls holding hands to go to the toilet, and some boys accompany boys.
There are quite a few boyfriends accompanying their girlfriends to the bathroom, but this is the first time I have seen a girlfriend accompanying her boyfriend.
"Me too. In life, it doesn't matter if you try something harmless." Luo Liyan shrugged nonchalantly.
As soon as he finished speaking, he saw the little follower beside Chen Shaoning coming out, but before he had time to do anything, he saw Luo Liyan.
The ferocity on his face stiffened, making it look very funny.
"You're here, what about Chen Shaoning?" Luo Liyan took two steps forward, put one hand in his pocket, and looked at him angrily, without the cute look just now.
Just like two twin sisters with completely different personalities, their attitudes change so quickly that there is not even the gap between switching and changing faces that is unique to dual personalities.
The boy swallowed, straightened his chest, and wanted to be provocative, but before he could say anything, his knees suddenly hurt, and he knelt heavily on the ground.
"I'll give you a chance, answer me after you think it through." Luo Li warned with a dark voice.
"Chen... Brother Chen just saw your boyfriend, so I talked to him inside." The boy said quickly.
In fact, Luo Liyan had already guessed it a long time ago, and she did all this just to show the boys next to her.
