After listening to Xiao Heyi for more than half an hour, Ruan Xia was still in a state of fog

"Do you understand?"

Xiao Heyi took the pen and nodded her head

She slowly looked up at him

"I guess I understand a little bit......

"Well, let's try"

Ruan Xia took the pen herself and began to do it

Well...... Thinking about the solution he just said, it took less than five minutes to write

"Oh, that's it."

Xiao Heyi was surprised, how could it be so fast, what was she doing

I took the scratch paper, glanced at it, and put it down

"You only wrote the first step, or copied it in the title" looked at her helplessly

"Didn't you say that this is also a known condition, and simultaneous equations are also scored"

"Then why don't you keep counting?"

"I won't, I've said it's too difficult, forget it, Xiao Heyi, give up, I can't learn"

"It's just the difficulty of liberal arts math, science is even harder than this"

"How do you know?"

"I've done it"

"But how can you do it without learning it?"

Xiao Heyi glanced at her "self-taught"

Ruan Xia stopped talking now

Okay, she can't come to teach herself this kind of operation, after all, she is not a scholar like him and Ruan Xi

Her literature is not as good as the science comprehensive, so she has to choose science with more certainty, but if science and mathematics are really so difficult, she may abandon science from literature

"Xiao Heyi, do you think I should study liberal arts?"

Xiao Heyi frowned slightly and raised his eyes to look at her

She immediately lay down on the table

"You said that science and mathematics are so difficult, my level is only enough to cope with liberal arts, so I will work more literature and mathematics when the time comes."

After saying that, he lowered his head and began to dangle it

There was silence in the living room for several minutes

"You choose science"

Ruan Xia raised his head to look at him, he looked into her eyes and said to her, "I also choose science, and I will be responsible for your mathematics later"

This sentence is not so sonorous and powerful, but it does enter the depths of Ruan Xia's heart

It's as if he's saying, I'm in charge of your future life

Ruan Xia snickered in her heart for a while

Then he pursed his lips and smiled and asked, "Really?" You didn't lie to me? ”

"Well, when did I lie to you"

"Okay, let's talk about it again, maybe listen to it a few more times"

And then it looked like life was worse than death

Xiao Heyi really couldn't do anything about her when he saw her like this, so he raised his hand and touched her head, "Okay"

Then he took the pen from her hand and prepared to continue speaking to her

She found that Xiao Heyi seemed to like touching other people's heads, was it the sequelae of having pets before?

If he also loves pets, that's fine

Finally, in the case of Xiao Heyi's fourth lecture, this topic can get five points

Ruan Xia was agitated to death

This undoubtedly inspired the heart to conquer mathematics

Xiao Heyi looked at her with great interest

Well, that's a good sign

thought of something, and then asked her, "Ruan Xia, will the third year of high school start tomorrow?" ”

Ruan Xia was calculating the problem and didn't look up at him

The pen didn't stop, and he said while calculating, "Yes, my brother and they are going to start evening self-study tonight, what's wrong?" ”

"It's okay, ask"

Ruan Xia was a little puzzled and asked why this was done

I didn't think much about it, and continued to do the math

This feeling is not right, I have been stuck in the same place several times and can't go on, how can this be

Pick up the test paper and scratch paper and give it to Xiao Heyi

"I don't think this is right, I won't get stuck here"

Xiao Heyi took the test paper and scratch paper

The first steps are pretty good, and the fifth step is a bad one, but it's really much better than before

"This place is done wrong, you try it with the Vedic theorem".

Vedic theorem? Mr. Veda theorem didn't talk about it
