"No, he actually gave the answer. Lin Siyu's mouth opened wide in surprise.

Tan Xiaoxiao pursed her lips and said nonchalantly: "What's so surprising about this? It must be an answer that is said casually, it can't be correct!"

"No, it's not. Lin Siyu shook his head and handed his exercise book to Tan Xiaoxiao.

On top of that, there are mathematical formulas and problem-solving processes.

"Look. ”

"What are you looking at?" Tan Xiaoxiao asked with a frown.

Unlike a student like Lin Siyu, Tan Xiaoxiao has no interest in mathematics at all. These boring formulas, she felt big just by looking at them.

"When Mr. Gao was writing a question on the blackboard just now, I copied it down and did it...... Well, look here, this answer. Lin Siyu also knew her best friend's situation, and stretched out her finger and tapped twice on the final answer to the math problem.

“x=1\/5？”

Seeing this answer, Tan Xiaoxiao was stunned for a moment, and then exclaimed in a low voice: "This liar, he actually calculated the answer to this question?"

Lin Siyu nodded.

Gao Zi's math problem is not difficult. As long as you don't desert in this class and listen carefully, you will be able to use formulas to calculate the answer. But the problem is that Li Sichen did not check the calculation on the blackboard or manuscript paper, but just glanced at the question and gave the answer directly......

This is a bit astonishing! This shows that he not only has a strong mental arithmetic ability and memory, but also knows a lot about mathematical formulas, at least the ones explained in today's class! Otherwise, it would be absolutely impossible for him to do this.

"I didn't expect this liar to know math...... Now the threshold for deception is inevitably too high, right?" Lin Siyu muttered quietly, looking at Li Sichen's gaze, there was less hostility and more curiosity.

Gao Zixi was also stunned by Li Sichen's mental arithmetic ability, and after a while, he asked, "Have you reviewed what I am going to talk about today?"

"Sort of. Li Sichen nodded.

"This kid must have reviewed the textbook in advance, and he is also very good at self-study. When I was lecturing, he felt that all the problems had been mastered, and there was no need to listen to the lecture again, so he slipped on the table and slept ......" Gao Zixi pondered in his heart.

The more she thought about it, the more she felt that this was the case.

"It's a good thing to study, but it's a big mistake to be complacent and think that there's no need to listen to the lecture anymore! No, I have to kill this kid's arrogance and let him know that his level is still far behind. Otherwise, if this goes on like this, a good seedling will be destroyed!"

In Gao Zixi's eyes, Li Sichen has become a good seedling in mathematics.

By just revising, I learned the formula and was able to use it accurately, and I also relied on mental arithmetic to solve the problem and give the correct answer...... What is such a student who is not a good seedling in mathematics?

Since it is a good seedling, it should be even more strict!

Turning around, Gao Zixi picked up the chalk and wrote a question on the blackboard: "Li Sichen, you can solve this problem." As long as you can unravel it, my classes in the future, whether you are sleeping or reading idle books, will be fine. But if you can't solve it, you will have to be careful and serious in the future. If I let you get distracted, the punishment will be several times greater than that of the other students!"

Seeing the math problem on the blackboard, Lin Siyu couldn't help but gasp: "Teacher Gao actually took out this problem, the big liar is really difficult this time." ”

"What, is this question difficult?" Tan Xiaoxiao asked curiously.

For a math idiot like her, this question is just as incomprehensible as the previous one. As a result, she couldn't tell which question was more difficult.

Lin Siyu glanced at her, and said angrily: "This problem appeared in last year's Mathematics Olympiad, and few people in the country did it right, do you say it's difficult?

Tan Xiaoxiao replied nonchalantly: "What's not to do? I'll just go to liberal arts in the future." Anyway, I'm not interested in math. You say, when I grow up, I don't want to be a mathematician, what do I do with so many formulas? I can't, these things can still be used after I leave school. ”

Immediately afterwards, she became excited again: "You say that this question is a difficult problem in the Olympiad competition?

Lin Siyu shook his head and didn't give a clear answer: "At least I can't answer." ”

Tan Xiaoxiao said: "Siyu, you are the top student in our class. If you can't even answer a question, the big liar will definitely not be able to answer it! Hmph, let him pretend to be forced, this time he will always make a fool of himself, right?"

"Not necessarily......" Lin Siyu whispered in his heart.

At the same time, Li Sichen also stepped onto the podium. However, after writing a 'solution' at the bottom of the question, he stopped and did not answer the question in one go.

"I don't know how to do this, do you?" Gao Zixi smiled, this is what she wanted.

Turning around and picking up the water cup on the lectern, after taking a sip of tea, she said slowly: "Therefore, whether it is being a person or studying, you can't be complacent." Don't think you know everything, when in fact you do, it's just a drop in the ocean...... Huh?"

When she put down the water cup and turned around, she was surprised to find that Li Sichen had begun to solve the problem. And the degree of writing is very fast, and the thinking never seems to stop. One mathematical symbol after another, formulas, flowed out of the chalk he held in his hand like flowing water, swaying freely.

Gao Zixi was stunned.

Not only her, but all the students in the third class of the first year of high school were also stunned.

It's just that the students were stunned because they couldn't understand what Li Sichen wrote at all.

"Siyu, didn't you say that this math problem is difficult? How can he know how to solve it? Hey...... No, what do these symbols and formulas he wrote mean? Why don't you seem to have never seen them? Don't you make them up yourself?" Tan Xiaoxiao said suspiciously.

Lin Siyu was also confused: "I haven't seen these symbols and formulas either......"

The rest of the students were also whispering, discussing whether Li Sichen was scribbling.

"It's just scribbled, I've never seen these formulas before!"

"I don't think it's scribbled, these formulas and symbols are unfamiliar, but they have a sense of incomprehension. ”

At this time, Li Sichen also finished the question, and gently threw the remaining small half of the chalk into the chalk box.

After clapping his hands, he said with a smile: "It's over, Mr. Gao, you see this answer, right?"

"Yes......" Gao Zixi nodded subconsciously, then turned around and asked in disbelief: "How can you still know linear algebra?"

The students couldn't see it, but she, a top student in the Department of Mathematics of a famous normal university, recognized at a glance the formulas that Li Sichen used to solve the problem, all of which were in linear algebra!

It's a math course in college! And even college students are so busy studying. How can a fifteen or sixteen-year-old high school student understand and still be able to use it freely?

"Linear algebra? Damn, buddy, dare you still be a scholar? It's awesome! In the future, it's up to you!" Zeng Yi, who was at the same table, was shocked, and accidentally shouted out what was in his heart.

No one laughed at him.

Because everyone is still in a state of shock and has not come to their senses.

Lin Siyu was also dumbfounded.

She has always been regarded as a top student by her teachers and classmates, and she thinks so herself. But today, after reading Li Sichen's watch, she suddenly felt that her title of 'Xueba' was a bit undeserved......

"That's not great, is it? I just did a little more research on math because of my profession. Li Sichen scratched his head and said a little embarrassed.

"What does this mean? Aren't you a student? Why do you still have a career? Is it a part-time job in your spare time? But what kind of part-time job does you need to use linear algebra?" asked Gao Zixi curiously.

Li Sichen smiled, didn't answer, and changed the topic: "Teacher Gao, do you count?"
