After speaking for the second time, Xiao Ran found that the uncle in front of him still didn't say a word and didn't react.

It was only then that he suddenly realized a problem.

This uncle shouldn't be a "civil science", right?

There is a passion, but the foundation is not so solid.

Thinking like this, he glanced at the Goldbach conjecture book again, looked at the uncle who was still staring at the Olympiad math problems, and suddenly felt some emotion in his heart.

really live to learn all the time, if in his previous life, when he was young, he could have half of this uncle's spirit of curiosity, how could he ......

Thinking of this, Xiao Ran couldn't help but be full of respect for this uncle.

At the age of gray hair, there are really not many people who can study so diligently.

He wanted to encourage the uncle again, but then he suddenly saw him nodding at himself in a panic.

I also vigorously said that I understood, understood.

Seeing this, Xiao Ran smiled bitterly in his heart, this scene is really too familiar.

Before, he seemed to be like this.

When I ask someone for advice, even if I don't understand it, I will always panic and pretend to understand when I see the other person's "expectant" eyes.

Who hasn't had a time to love face!

What's more, it's still an old man who is asking a middle school student for advice.

Seeing this, Xiao Ran decided to work harder, he must teach this uncle today.

We must not dampen the uncle's enthusiasm for learning in the future!

So, he laughed and deliberately said:

"Understood, uncle, in fact, I just suddenly thought of another easy way, and I don't know if it will work, let's study it together."

Han Shiqi couldn't laugh or cry, he saw that Xiao Ran didn't seem to believe that he understood, and he looked like he was smiling.

He is too familiar with this look, and he used to face students who didn't know how to pretend to understand.

But he never thought that one day he would become the student in the scene, and the roles were reversed, which was really a good reincarnation.

So, he smiled bitterly and hurriedly wanted to explain.

However, at this time, he suddenly heard the other party say that there was another way, and Han Shiqi couldn't help but be curious again.

The method that Xiao Ran explained to him just now was the same as in the textbook, and Han Shiqi was naturally clear about this.

However, Han Shiqi already felt that this method was very simple, and he couldn't think of any other better solution for a while.

But how could this student say there was an easier way?

Seeing this, Han Shiqi was silent again, and he decided to take another look.

Seeing Han Shiqi's appearance, Xiao Ran secretly said that he really guessed his thoughts, he really didn't understand just now.

He was happy in his heart, but on the surface he began to explain the second method that suddenly came to mind in the afternoon.

In fact, this method is indeed more concise, and the steps are about a quarter less than the solution in the book.

It's just that the formulas and theorems used in this method are relatively obscure and are not commonly used.

This is also the reason why Xiao Ran chose to use the book method to explain to the uncle at the beginning, instead of using this.

However, now that the uncle really can't understand the solution in the book, he can only try to use this method.

Dead horses should be treated as live horse doctors!

Because the formula theorem is biased, Xiao Ran spoke very slowly this time.

It is explained in detail almost step by step, and the theorem used will be simply deduced and proved.

Therefore, although he was very familiar with the steps of answering the question, Xiao Ran still spent nearly 20 minutes to finish this solution.

This time, Xiao Ran noticed that the uncle nodded frequently during his lecture, and from time to time he showed an expression of sudden realization.

Seeing this, Xiao Ran couldn't help but breathe a sigh of relief.

It seems to be done!

It really happened, because Han Shiqi was really shocked!

He didn't expect Xiao Ran to really give the second method in one go, and it was really more concise.

Almost as soon as Xiao Ran wrote down those theorems, Han Shiqi felt a little.

Later, under Xiao Ran's constantly changing calculations, Han Shiqi felt that his thinking had also been opened.

He really hadn't thought of this method.

In fact, for this problem, Han Shiqi also knows two solutions.

But at this time, he found that the two solutions he knew were not as simple and effective as Xiao Ran's.

And listening to Xiao Ran, this is what he just thought.

Han Shiqi was naturally shocked in his heart, and he couldn't help asking:

"Classmate, this method is great, can I ask who you learned the Olympiad from?"

At this time, he felt that he had completely misunderstood, this classmate was by no means a newcomer to the Olympiad, and there must be an Olympiad boss behind him.

But in the next second, Han Shiqi was shocked again, because he heard Xiao Ran say such a sentence lightly.

"Hehe, these are all things that I learned by myself recently, and we don't have an Olympiad coach in our school."

Seeing Xiao Ran's simple smile, Han Shiqi's heart instantly turned into a huge wave.

He turned out to be a budding newcomer!

Han Shiqi was secretly frightened, when he saw Xiao Ran suddenly running to the bookshelf and bringing a book.

It is "Pei Yuan Course"!

Then, he saw that Xiao Ran handed him the book with a smile as soon as he sat down:

"Uncle, this question is on page 166 of this book, example question 4.5 of Chapter 4, subsection 4."

"The method of solving the problem is the same as the first one I mentioned, maybe what I just said is not thorough enough, you can read it again against this book when you have time."

Han Shiqi subconsciously took it, and he turned the letter to page 166 suspiciously.

To be honest, he couldn't believe that anyone could remember the number of pages and chapter numbers of a question so clearly.

Even he himself only vaguely remembers in which chapter there was this question.

But when he found page 166, he saw the example question 4.5, which was exactly the same as what Xiao Ran said.

Not only that, Han Shiqi was also surprised to find that every step Xiao Ran wrote just now was exactly the same as in the book.

This......

"How do you remember this book so clearly, did you memorize this book on purpose?" Han Shiqi asked suspiciously.

"Hey, hey."

Xiao Ran smiled, he sincerely wanted to encourage this uncle, so he added a little fuel and vinegar and continued:

"Yes, uncle, don't look at the Tao I am telling you here, it seems to be very powerful, in fact, I am just used to memorizing all the problems I see."

"In my opinion, the subject of mathematics is certainly important, but if you work hard to make up for it, you will never give up, and it will never let yourself down."

"Uncle, you are the same, don't give up your love and interest in mathematics because of a difficult problem!"

Looking at Xiao Ran's bright smile and hearing that he was constantly cheering for himself as an old man, Han Shiqi was a little moved.

When he first met Xiao Ran last week, he still thought that this kid was so ambitious, and a senior high school student who had never been exposed to the Olympiad had a whim to participate in the Olympiad.

At that time, he was not optimistic about Xiao Ran, but based on the passion of the other party, he made a list of books for him.

But that book list doesn't mean to dissuade you from quitting, after all, the questions in it are all difficult.

Even when he saw Xiao Ran again today, Han Shiqi was still not very optimistic about him, and even felt that he was a little too confident for a while.

So, he wanted to hint to Xiao Ran to give up early and take the college entrance examination honestly.

But after this contact just now, he felt that he was really wrong, very wrong.

This student is different, and it's really not easy!

There is no coach, no foundation, nothing is known, and the river is crossed from scratch by feeling the stones.

But such a student gave himself too many surprises today.

Perhaps, as he said, talent is important, but diligence and perseverance are also indispensable, and hard work never deceives.

What's more, this student's talent is also incredibly strong.

Thinking of this, Han Shiqi suddenly felt that his long-lost blood and passion had returned.

He decided.

He wants to do one more vote at the end, maybe this student can help him realize his lifelong wish.

So, he cleared his throat, and then said to Xiao Ran with a smile:

"Classmate, do you want a coach?"
