Sister, can I be a maid too?

Combining conic sections and vectors? That's a bit novel. Let's try solving it using parametric equations...

Jiang Yubai found it easier and easier to work on the problem. After solving the last one, he even felt a little unsatisfied.

He didn't even bother to check; he simply closed the pen cap and looked to the side.

Lin Jianxia was frowning as she stared at the draft paper on the table, seemingly having encountered some kind of problem.

The math test paper is full of answers, but now I'm focusing on physics.

Jiang Yubai didn't disturb them, and casually picked up the math test paper that was placed aside, and started reading it from top to bottom.

The exam paper was filled with writing, and all the important information in the questions was carefully circled.

But the solution process...

On the other end.

Lin Jianxia stared at the calculation steps on the draft paper, biting her lower lip as she pondered deeply.

The force analysis should be drawn like this, and the direction of the friction force is set correctly, but why can't I get the answer from the formula I've written?

She was frowning as she repeatedly calculated when she suddenly heard a laugh that she couldn't help but let out.

Lin Jianxia snapped out of her daze and looked around blankly.

Jiang Yubai was looking at an exam paper with a big smile on his face, clearly engrossed in it.

What are you doing? You can't be laughing while doing a test.

But the next second, Lin Jianxia's brows furrowed sharply.

This exam paper... why does it feel a little familiar?

Isn't that her exam paper?

"What are you doing!" Lin Jianxia said angrily. "Is my test paper that funny?"

Jiang Yubai seemed to have seen something amusing and couldn't help but chuckle again. Upon hearing this, he quickly coughed twice to compose himself.

"Hey, have you finished writing?"

Lin Jianxia was silent for a few seconds, her shoulders slumped slightly, and her voice carried a rare hint of frustration:

"I still have two physics questions left, but I can't seem to get the calculations right no matter what I do... Could you teach me first?"

She gritted her teeth and looked up at Jiang Yubai:

"I'd like to know... what exactly are you laughing at!"

"What are you laughing at?"

Jiang Yu laughed, handed over the test paper, and pointed to a question for her:

"Teacher Lin, how come you calculated the volume of a triangular pyramid to be 'three-fifths square root of three'?"

As he spoke, he couldn't help but laugh out loud again:

"Have you ever seen an answer with a volume like this?"

Lin Jianxia stared at the answer for a few seconds, then tried to defend herself:

"...That's how the formula is. Just fill in the data and you'll get the answer! You can't just change it because it's wrong, can you?"

Seeing that Jiang Yubai was about to laugh again, Lin Jianxia angrily punched him:

"If you're going to teach, then teach quickly, stop talking nonsense."

"Okay, okay~"

Jiang Yubai finally managed to suppress his laughter, moved his chair closer to her, and tapped his pen on the question:

"Look, this is what the title says..."

He patiently broke down the problem, guiding her step by step through analysis, equation formulation, and simplification, until his own throat became dry before he finally stopped.

"So, did you understand that?"

Jiang Yubai wanted to hear Lin's opinion, but he was slightly taken aback when he turned his head.

Lin Jianxia's gaze wasn't on the exam paper at all; she was staring at him, her cheeks flushed, and her ears like ripe cherries.

Caught off guard by their gazes, the girl quickly turned her face away as if she had been burned.

She stared at the exam paper between the two of them, her voice stammering:

"Hmm, um... I think I understood a little bit..."

Ok?

Jiang Yubai looked at her suspiciously for two seconds, then suddenly realized—

This guy...

Could she be that angry?

Chapter 55 Lin Jianxia's Reward (Seeking monthly votes~)

No wonder, I did seem a bit too aggressive just now.

Things like "Even kindergarten kids know how to set up this equation," or "I could solve this kind of problem with my eyes closed"...

Who wouldn't be angry after hearing that?

Jiang Yubai hesitated for a moment, but still comforted him:

"Well, actually... it's already pretty good that we've managed to do this much. I originally thought the situation would be worse."

Sigh, saying this goes against my conscience.

What can we do? If Li Yang were sitting next to us, he would have already started unleashing his full power.

The problem is, this is Lin Jianxia...

He didn't even use much force, and the other person's ears were already this red.

If I were to be any harsher, what if the little pearls actually fall out?

Perhaps Jiang Yubai's words of comfort had an effect, because Lin Jianxia gave a soft "oh," lowered her head again to stare at the test paper, and didn't say anything more.

Jiang Yubai glanced at her a few more times.

Although her face was flushed with anger, her expression remained relatively calm; at least she showed no signs of grabbing whatever was at hand and fighting him.

He finally breathed a sigh of relief and gently tapped the next question with the tip of his pen:

"Come on, let's look at this one..."

This time, his tone softened considerably, and he even managed to suppress his urge to criticize when Lin Jianxia looked completely bewildered, patiently explaining it a second time.

—The school should really give me the title of outstanding teacher.

Jiang Yubai thought to himself.

Half an hour later.

After going over all the test papers and exercise books, Jiang Yubai breathed a long sigh of relief.

When Lin Jianxia, ​​who was writing and calculating, looked up with a happy expression, he slowly began to speak:

"So, the homework is done, the questions have been explained, and now... we should both have a pretty good idea of ​​each other's levels, right?"

Lin Jianxia's face, which had been beaming with joy at solving the problem, suddenly froze, and she looked at Jiang Yubai with a somewhat subtle expression.

"Let me give a summary."

Jiang Yubai shrugged.

"Your physics and math skills... are about the same as my Chinese and English, you could say that?"

Lin Jianxia opened her mouth as if to refute, but in the end she could only mumble an "oh".

Jiang Yubai stroked his chin, suddenly becoming curious:

"Lin Jianxia, ​​why did you choose physics when you're so bad at it?"

"I'm pretty good at chemistry and biology," Lin Jianxia muttered, "who knew physics would be so hard..."

You have a talent for chemistry, but biology... well, that could be considered a humanities subject, right?

"Never mind, I was just asking casually." Jiang Yubai shrugged.

Anyway, I can't change my course selection now.

He piled up the assignments from several courses and sighed.

"So, my dedicated and conscientious teacher Lin, how do you plan to help me save my appalling Chinese and English scores?"

Lin Jianxia pursed her lips: "...You go first."

also.

Jiang Yubai took the test paper he had just finished explaining, thought for a moment, and then asked:

"You should be able to do all of what I've told you, right?"

Mentioning this, Lin Jianxia immediately perked up, and her tone became lighter:

"I've mastered them all. I'm sure I can do them again next time I encounter this problem."

To everyone's surprise, Jiang Yubai poured cold water on the situation with a blank expression:

"Where will you find a question that is exactly the same as the one you are supposed to answer? If the conditions are slightly changed or the question is phrased differently in the exam, you'll probably get stuck again."

"...Then what do you suggest we do?"

"What should we do?" Jiang Yubai shrugged.

"Practice more. I'll pick a few unusual problems for you to do each week. If you can't solve them, I'll explain them to you."

"Once you've mastered the typical questions and past exam papers, I'll teach you some tips and tricks. You'll definitely be able to improve your score by 40 or 50 points."

Hearing these grand words, Lin Jianxia couldn't help but mutter a complaint under her breath:

"Forty or fifty points...you really dare to say that..."

Before Jiang Yubai could gloat for a moment, she changed the subject again:
