Facing these two questions in the preliminary round of the Olympiad again, Xiao Ran had mixed feelings.

These two questions have not changed at all.

It may be because of these two questions that Xiao Ran was admitted to the Department of Mathematics by mistake, became a mathematics teacher, and embarked on the road of Olympiad mathematics coach.

It can be said that Xiao Ran will never forget these two questions.

He has already mastered these two questions, and he has mastered at least 3 solutions to each problem.

Although these two questions are the finale of the preliminary round, it is really not difficult to be honest, but I was too good at the beginning.

So much so that he missed the opportunity to participate in the Olympiad and contact Susu, and indirectly missed the girl who was like a white moonlight.

Fortunately, I am back again.

"What, is there a problem?"

Teacher Wang Yongan saw that Xiao Ran was a little distracted and asked.

Hearing Teacher Wang's question, Xiao Ran realized that he seemed to be a little obvious.

His mind was in a hurry, and he hurriedly replied with a look of "grievance":

"Teacher Wang, where are you looking for this question, it seems too difficult."

Seeing Xiao Ran's embarrassed look, Wang Yongan felt as if things were still turning around, and he said with a calm face:

"Hmph, you know it's difficult now, it's better than when you go to the exam room later."

"But let me tell you, I'm not embarrassed for you, these two questions are the real questions of the preliminary round of the past two years."

Seeing that there was nothing unusual about the old class, Xiao Ran was a little settled in his heart, and he nodded:

"Then I'll give it a try and try to answer more."

Teacher Wang Yongan saw that Xiao Ran began to concentrate on answering the questions, so he took him a glass of warm water, and then walked out of the office with the door closed.

In fact, he originally wanted to supervise Xiao Ran's answer on the spot.

It's not that he is afraid of Xiao Ran cheating, but he is putting pressure on him on the side, after all, he really doesn't want Xiao Ran to participate in the Olympiad competition.

Because Xiao Ran is really not suitable, he doesn't want to see this good seedling in front of him ruined.

After all, the past is still in front of us!

But perhaps it was Xiao Ran's youthful and frivolous words that moved him, and Wang Yongan went out unconsciously.

Whose youth is not hot-blooded!

At this moment, he didn't want to disturb Xiao Ran!

Seeing the old class suddenly and quietly leave, Xiao Ran felt a little puzzled.

He vaguely remembered that in his previous life, Lao Ban had been watching him answer questions from the side.

But Xiao Ran didn't think much about it, he was busy thinking about how to deal with the current situation.

Xiao Ran knew that he would definitely win this game, but he didn't want to show any flaws.

Although there are more than 3 solutions to each question, Xiao Ran still carefully considered it and eliminated the simple solutions that involved the derivation of university knowledge.

He is also in no hurry to write the answer, in case the old class suddenly comes back and sees him doing it so quickly, it will inevitably be a little troublesome.

Therefore, Xiao Ran deliberately grinded and wrote and drew on scratch paper, and finally he chose a decent solution.

But even though Xiao Ran deliberately slowed down, he still completed these two questions in half an hour.

No way, as soon as he saw the Olympiad questions, his hands were itchy, and he was really familiar with these two questions.

Seeing that there was still half an hour left, Xiao Ran couldn't help but pat his head.

Wouldn't it be a little too fast?

Just then, footsteps were heard in front of the office door.

Xiao Ran thought that the old class had returned, but when he looked up, he found that two teachers who were not familiar with him walked in.

Although he didn't know him well, Xiao Ran still said hello with a smile, and explained to them that he was doing Teacher Wang's question here.

The two teachers didn't say much, they smiled and nodded, and then began to discuss the problem in a whisper.

Of course, occasionally I can't help but argue loudly.

After a while, a chubby teacher who had just come back passed by to fetch water, and he asked Xiao Ran with a smile:

"Didn't bother you to do the questions, eh, are you done?"

Seeing that the other party had already caught a glimpse, Xiao Ran had to smile and replied, "Well, don't bother, I've just finished it." ”

"Wait a minute, alas, why hasn't this old king come back, you wait a little longer, he may have something to delay."

After the teacher finished speaking, he filled Xiao Ran's cup with water, and seeing this, Xiao Ran naturally thanked him repeatedly.

"Squeak!"

At this point, the office door opened again.

Xiao Ran looked up and saw that this time it was the old class, and he was back.

But before he could speak, he heard the teacher beside him say to the old class:

"Lao Wang, why did you come back, this classmate has been waiting for you for a long time, and the questions have already been completed!"

"Done?" Wang Yongan was a little incredulous when he heard it, he looked at the time, and it was only 40 minutes past.

So he asked Xiao Ran, "Are you done?" ”

Now, Xiao Ran naturally couldn't deny it, he had to force a smile and nodded: "I just finished it." ”

Thank you so much for the fat teacher who helped me speak!

Wang Yongan still couldn't believe his ears.

After the self-study class last night, he didn't go straight back to the office.

He hurried back to his office after struggling outside for a few cigarettes.

Because he suddenly remembered that the teacher would go back to the office after class.

At that time, the office can be a little noisy.

Although he also knew that with Xiao Ran's strength, he might not be able to pass tonight's test.

But he still didn't want someone to affect Xiao Ran's state at this time.

But he didn't expect that as soon as he entered the door, he heard this news that surprised him.

That's it!

Xiao Ran actually finished it ahead of schedule!

However, when he saw that Xiao Ran had already written the answer sheet full of answers, he had to believe this fact.

But how is this possible?

You know, when I showed these two Olympiad questions to other teachers in the morning, everyone unanimously said that it was very difficult.

Even they don't dare to pack the ticket to be completely right in a short time.

What's more, it's Xiao Ran, a student who usually hovers around 125 points in mathematics.

Is it scribbled?

After all, I just said that I only need to do half of the steps correctly.

With this in mind, Chen Yongan began to examine Xiao Ran's answer sheet.

But at this glance, he was shocked in his heart.

Because, the first big question turned out to be all right!

Not only is the result correct, but even every small step in between is exactly right.

Even, the steps are so detailed that there is no reason to deduct points!

This......

Wang Yongan forcibly suppressed the surprise in his heart and looked at the second big question.

This is an inequality synthesis problem, and this one is more difficult.

According to Lao Liu, who accosted him just now, only one person in their key class has completely done it.

But this time, Wang Yong'an was even more stirred up by the stormy waves.

Unexpectedly......

Get it right again!

The steps are so detailed that there is not even a single flaw in the deduction of points!

If you really want to pick a bone in the egg, it is that the method of solving these two problems is too decent, and even a little stupid.

But what does it matter?

You know, how many people can't even think of this stupid method.

Putting down the answer sheet, Wang Yongan's heart couldn't calm down for a long time.

It turned out to be a perfect score!

It's still a perfect score made 20 minutes in advance!

At this moment, Wang Yongan's heart was a little happy, but at the same time, he was a little disappointed.

He didn't know what to say for a while.

He reached into his pocket, trying to pull out a cigarette to calm himself down.

But this time he felt empty, and his pockets were empty.

Only then did he remember that he had just finished smoking the few cigarettes he had.

The cigarette cases were all thrown away.

Realizing this, his hand froze there, motionless.

After a long time, he muttered:

"Xiao Ran, you won!"
