My subject turned into a beautiful girl

"Analyzing this rationally, my exam scores correspond to the quality of my interactions with them during the incident. Now, what I need to do is treat everyone equally, that is, to ensure that the quality of these interactions is 'the same,' which means..."

An Yi scratched his head, feeling a bit uneasy about the results of his analysis.

"I want the scores for math, physics, chemistry, and biology to be as similar as possible after being converted to a percentage system!"

In other words, if he wants to avoid a chaotic situation as much as possible, he either needs to get full marks on all the tests or he needs to control his scores precisely!

Okay, there's no fundamental difference between these two things. Someone who can do the latter might even be more skilled than the former.

That's not the most pressing issue, because the next monthly exam isn't until a month later. The most pressing thing right now is that in about ten days, An Yi will be participating in the high school league.

But should we deliberately do poorly on tests just to balance the level of favorability?

The idea only briefly flashed through his mind before An Yi rejected it. Every opportunity to improve favorability was crucial and couldn't be wasted, plus deliberately doing poorly on the test would be unfair to his older brother! He still had principles.

Instead of deliberately doing poorly on tests, An Yi thought about how to improve his impression of other subjects...

At this moment, Wang Xinze's continued rambling also reached my ears.

"Of course, these are just common solutions. Some higher-quality gala games have different solutions because certain characters have special settings in these situations, you know? For example..."

"An 'official wife' who can win the hearts and minds of all the characters?" An Yi suddenly had a flash of inspiration and continued the conversation.

Multiple female protagonists, isn't that just a harem? Of course, a harem needs a ruler, and an authoritative figure capable of suppressing all enemies can even help maintain balance to some extent!

"Yes! That's a viable solution, but only if she can truly win over all the characters. In that case, it's okay if you raise the favorability of that one character a little."

Wang Xinze continued to share his experience with great enthusiasm.

"Of course, it can't be so high that other characters have no room to interfere at all. This is actually a very difficult thing, because making other characters truly convinced is secondary."

Theoretically, you'd also need to figure out how to get her to agree to you building up your relationship with other characters, so you'd have to judge based on various details. But I've never seen a visual novel this detailed before, so it's actually quite easy...”

"Got it! Thanks, bro. You can copy my homework later!"

An Yi's eyes lit up, and he made a solemn promise.

Having said that, he obviously already had a "first wife" in mind.

Mathematics, without a doubt, is her, and deserves to be her... Whether from the perspective of its status as a discipline in reality, its corresponding identity in the world it describes, or its own level of acceptance, it can only be her!

"Hey, aren't we going to continue? Actually, I still have a lot of strategies to share." Wang Xinze smacked his lips, sounding somewhat unsatisfied.

"No need. Once you understand one path, you can comprehend all paths. I've already achieved enlightenment!" An Yi joked with him while organizing his thoughts.

"What kind of epiphany?"

Just then, a pleasant and familiar voice suddenly rang out from the side.

"Big brother!"

An Yi instantly recognized the voice, turned his head, and found Xia Qing standing next to his desk, her gaze fixed on the tabletop, seemingly looking at something.

"I was just about to come find you. Um, about the follow-up information on the second round of the National Higher Education Institutional Entrance Examination..."

"No rush, no rush, school will be over soon, we can do it during evening self-study."

Xia Qing shook her head, reached out, and picked up the draft paper that An Yi had left on the table after finishing the exam, which he hadn't had time to tidy up yet. The most extensive part of the draft paper was the formula that An Yi had written down when proving the n-dimensional Cauchy inequality.

"I came to find you because I wanted to ask if you solved the last problem that was beyond the syllabus... Wow, you can even prove it using mathematical induction?"

"Mathematical induction?" An Yi asked instinctively.

"..." The two fell silent at the same time.

Wang Xinze looked around and quickly realized that this was not an area he could access. Even if he only touched it slightly, it might cause his "spiritual vision" to be forcibly enhanced, but because of insufficient sanity, he would only see terrifying and indescribable things... So he decisively fled and went to the place of the Five Grains Reincarnation for refuge.

"You don't know mathematical induction."

Xia Qing raised an eyebrow to confirm, her gaze sweeping over An Yi. This time, she wasn't looking at him like she was looking at a monkey who had just evolved into a human, but rather as if he had evolved again, like a "Stone Age Homo sapiens."

"But you used it completely?"

She shook the draft paper in her hand.

"Whether it's the first step of verifying the basic examples after knowing the two-dimensional and three-dimensional Cauchy inequalities and discovering the patterns within them, or the second step of inductively hypothesizing that the k-dimensional Cauchy inequality holds when n=k."

And when n=k+1, perform a partial fractional transformation on the k+1-dimensional Cauchy inequality to make it a combination of a two-dimensional Cauchy inequality and a k-dimensional Cauchy inequality. This third step of the inductive proof... your reasoning and proof steps are impeccable, a perfect application of mathematical induction!

"Well... I just... felt like this might prove it, so I tried doing it, and it actually worked! I didn't even expect that at first."

An Yi herself felt that her explanation was a bit dry.

But what else could he say? He truly derived it entirely based on his mathematical thinking ability at the time! It's just that after listening to his older brother's analysis, he now understands that this is actually called mathematical induction.

That said, the proof steps of mathematical induction that my brother mentioned... seem to be universal and can also be used to prove other formulas and theorems?

At this point, the light screen appeared—

You and Math were still having a lively discussion about that movie, which was perfect in every way. Naturally, you ended up mentioning the most interesting life phenomenon in the movie.

You tell mathematics that you've discovered that the specific everyday phenomenon isn't the most crucial element. The key is the experimental method used to determine the existence of that phenomenon; it can also be used to determine whether many other everyday phenomena truly exist.

[Mathematics is very interested in this!]

[Mathematics' favorability towards you +10]

[Mathematics: Current Affection Level 35/Normal]

Physics is quite dismissive of this. In her view, your discoveries were merely accidental, minor strokes of cleverness. They don't change the fact that you're still mediocre and unworthy of mathematics… Of course, in any case, you are slightly better than the completely useless person she initially expected.

Physics' favorability towards you increases by 1.

[Physics: Current favorability -9/dislike]

Physics is furious! She's trying to find an opportunity to attack and mock you, thereby ruining your image.

Where did this tsundere attitude come from? Don't you know that tsundere is outdated? No one will like someone like you who likes to use tsundere tactics to attack and mock others!

An Yi harbored malicious resentment in his heart, but didn't pay much attention to it.

He believed in mathematics, because a great mathematician wouldn't be prejudiced against himself because of a few words about physics!

"Tsk tsk, you can even refine your 'feeling'?"

At the same time, Xia Qing was amazed.

"Indeed, you should reconsider my previous suggestion. How about Ramanujan Ann as your English name? I think it suits you perfectly!"

"Big brother, you're in charge!"

An Yi said that his elder brother's kindness was like that of his second parents, and that it was just an English name, which was not important anyway, so he would just follow his elder brother's preference.

"Brother, Teacher Qiu wants to see you in his office. He said he has something to discuss, but he didn't say what it is." A classmate came to relay the message.

"Okay... Hey, where's Yinshuang?"

Xia Qing glanced in the direction of her seat but didn't see Zhou Yinshuang. Not wanting to delay any longer, she asked An Yi for help.

"When Yinshuang comes back later, could you please tell her for me that I will definitely be back within 5 minutes after school ends, and then we can go out for dinner together?"

"Okay, sure..." An Yi nodded in agreement.

Xia Qing had barely left the classroom when Zhou Yingshuang returned, almost immediately. She went back to her seat and began packing her things.

An Yi strode over, but before he could even speak, a piece of paper suddenly spilled out from a folder that Zhou Yinshuang had taken out of the desk.

The paper floated twice in the air with the airflow before he caught it with lightning speed.

An Yi glanced at it casually.

It was just a casual glance, but it looked... like some kind of mechanical design blueprint?

Just then, a screen of light suddenly popped up—

Physics finally found the opportunity she was looking for! Such a clumsy concept, such obvious errors—your stupidity is plain to see! She easily pointed out the problems and mocked that even a monkey wouldn't make such a mistake.

You have received information regarding errors in the design drawings and suggestions for correction.

An Yi: "???"

no……

You call this "mocking"?
