My Identity As A Schoolmaster Has Been Exposed

Chapter 199

Chapter 199 Do you understand?

In each class, there will always be two kinds of people, academic masters and scumbags, and there is no other distinction.

The reality is like this, and no one is allowed to question it.

Among the schoolmasters, there will be three, six, nine, and Yang Kaixuan is considered to be the best among the schoolmasters of the same grade!

But even so, the gap between him and Xu Cong is bigger than the gap between the last one in the school and him!

Yang Kaixuan looked at Xu Cong, and Xu Cong looked at the problem.

Yang Kaixuan looked at him Xu Cong and said to him, “I feel a little headache when I read the answer, Xu Cong, would you like to try?”

Xu Cong looked down at the question and asked, “Where did you find these old antique questions?”

He kept looking down at the test paper without looking at Yang Kaixuan.

Old antique?

Old antique topic?

When Yang Kaixuan saw him looking at the topic so intently, he threw out such a sentence, and suddenly he was speechless, and he didn’t know what to say for a while.

“I have finished all the college entrance examination questions in recent years. I think the difficulty is almost meaningless, so I found some of the more difficult ones.”

It’s harder!

Attention everyone, what he said is more difficult!

This is the truth of Yang Kaixuan, this question is just a bit difficult for a former first grader.

But the other people in the dormitory felt even more pressured. When Yang Kaixuan showed them this question, all of them got big heads.

“If Yang Kaixuan doesn’t look at the answer, he won’t be able to answer this question.”

“Hey! He sees that the answer can understand is already very good, okay! I think the answer is in the cloud!”

“You said, would Xu Cong?”

“Yang Kaixuan, don’t stump Xu Cong with this question!”

Yang Kaixuan shrugged and said helplessly: “I think too, but looking at Xu Cong’s attitude just now, this question is like Zhang Fei eating bean sprouts, a piece of cake for him.”

The other four roommates expressed doubts about this, so they all looked at Xu Cong.

Xu Cong raised his head for a while, looked at Yang Kaixuan, and said with a smile: “Although this question is difficult, there are four or five solutions.”

“You can understand the first question interval by looking at the answer!”

Yang Kaixuan was stunned by his words just now, and he didn’t respond at all. When his brain realized what dog Xu Cong was talking about, he asked afterwards, “Wha! What…Wait, what did you just say? “”???”

Xu Cong calmly said to him: “Your first question, do you understand?”

Yang Kaixuan nodded, but immediately he shook his head again, came back to his senses again, and continued to ask: “It’s not this sentence, it’s the last sentence!”

Xu Cong looked at him speechlessly, can you listen to me seriously!

He said again with some impatient tone: “I said four or five solutions?”

Yang Kaixuan’s eyes were about to stare out, and he said to himself: “Four or five kinds?! Four or five kinds of solutions? This, this, this?”

When the other four roommates heard Xu Cong say this, they were also stunned on the spot. They looked at each other, and the room became very silent for a while.

“Four or five kinds? Four or five kinds! How could it be possible! Did you get it wrong?”

“Xu Cong, are you sure?”

Xu Cong waved his hand and said faintly, “How come you look so rare and weird!”

Fuss?

This question, 300,000 candidates, only one scored 9 points!

Two got 8 points!

The average score is 0.31!

This is the finale!

Why is it in your mouth, it’s really as simple as one plus one equals two!!!!

Everyone’s scalp numb, and the whole person is trembling.

Xu Cong looked at these five people and asked them: “Which one do you want to listen to?”

But just after speaking, Xu Cong looked at their eyes, sighed, and said, “Let’s talk about it!”

A few people wished to hear more solutions, so they immediately echoed him: “Good, good!”

Xu Cong spoke directly to the proof of the second question.

“Let b=x, c=8ax, then question (2) is equivalent to…”

…

“The inequality drawn is somewhat similar to the last question of the Olympiad in earlier years.”

Mathematical Olympiad?

Yang Kaixuan was dumbfounded, how big is Xu Cong’s question bank?!

“In addition, there are similar problems in CMO.” Xu Cong said again.

Puff…

Is there something similar?

Are we ignorant?

Speaking, Xu Cong wrote down the relevant inequalities, and then went on to say: “In this case, it can be proved!”

The first method was said by Xu Cong, and it ended hastily.

Yang Kaixuan’s mouths were open and several people were speechless. Xu Cong patted the table, raised his voice, and asked, “Hey! Wake up, hey? Understand?”

Yang Kaixuan looked at him, and several people collectively shook their heads.

“Forehead…”

Xu Cong really separated them from Lin Mengjiao. Xu Cong thinks they should be much stronger than Lin Mengjiao.

They should belong to the type that can get through at one point, but Xu Cong still overestimates them!

At this time, even Yang Kaixuan said, “Xu Cong, are you too overestimating us? I think this method is more difficult than the topic!”

Others echoed: “I don’t understand the title, and we don’t even understand your answer!”

Xu Cong looked at them and whispered: “Uh~~ I thought you could do it!

But Yang Kaixuan and a few people shook their heads collectively, no, no, we can’t! Please let it go!

We are just ordinary students!

Please don’t treat it specially!

For the first time, Yang Kaixuan and the others felt the disadvantages of being a schoolmaster.

“Hey… Xu Cong, you might as well find a simpler talk—let’s talk!” Yang Kaixuan said with furrowed brows.

Seeing them like this, Xu Cong couldn’t help but said, “Okay, give me Zhang Yan’s paper and pen.”

A roommate hurriedly used it to play the papyrus, Xu Cong started his own thinking to answer, and explained:

For any given a∉0, x∉0, because…

…

First prove that f(x)≥1, because…

The inequalities in the process are listed as if building a building-in the same way, Xu Cong’s writing is like a waterfall, and he writes about the process!

But Yang Kaixuan’s five people were even more dumbfounded, because Xu Cong wrote so fast that they couldn’t keep up!

“Let me go! What is this and what? This step requires six or seven inequalities?”

“Damn! There’s more!”

“I’m going! I’m a scumbag, I’m definitely a scumbag!”

These are all in the top ten and twenty in the grade! The math scores are even among the top!

But looking at the proof process written by Xu Cong, I was willing to be a scumbag.

No way, people are better than people, so angry!

“too difficult!”

Xu Cong continued to write his answer: “At this time, f(x)=1(√1+x)+1(√1+a)+1(√1+b)-2…

Inequalities like the one mentioned by Xu Cong just now can be seen everywhere, not only inequalities, but also various squares are used, and there are so many of them.

When the final answer was written, this scribble was almost not enough!

After reluctantly writing the last long inequality, Xu Cong stopped writing.

Get the final result: “To sum up, the original inequality holds.”

Yang Kaixuan’s five people looked at the answers filled with sheets of paper, and they were all dumbfounded.

Especially the last inequality, like skewers of lamb, there are 4 or 5 skewers on a common stick!

And this, it’s like having five leg of lamb skewered! It’s too complicated!

It makes people take a breath when they look at it!

“hiss…”

The five Yang Kaixuan had scalp numb, and the answer was in front of them, but they couldn’t understand it!

This kind of thing is extremely tormenting for Xueba!

They could only stare at Xu Cong blankly, giving up understanding, and saying with emotion: “Xu Cong! Are you still a human?”

Xu Cong looked at them, frowned slightly, and asked, “Don’t understand?”
