After a few pleasantries, Xiao Yang hung up the phone.

I have to say that Xie Lin is still very good at being a person, and after discovering his mistake, he called to apologize as soon as possible, although Xiao Yang may not care about this little thing, but I have to say that he did it, which really made people feel a lot more comfortable.

Even with it, Xiao Yang even had a lot of thoughts about reading.

After continuing to gnaw on the book for a while, the phone rang again, and it was Coach Wang from the driving school calling.

Seeing this call, Xiao Yang suddenly smiled.

From today, let's resist driving without a license!

It doesn't matter if it's a temptation of interests, but Coach Wang's efficiency is really not covered.

Xiao Yang's driver's license was successfully obtained, and he also came with a set of well-preserved second-hand college textbooks.

It is said that it is extremely well preserved, and it is for Xiao Yang.

The textbook is clean, and there are occasional notes, and the whole book seems to have been turned many times, which is naturally not good for others, but for Xiao Yang, this is exactly what he needs the most.

I returned to the dormitory, put the textbook on the table, picked up the high math textbook and read it for a while.

A familiar feeling suddenly emerged.

When he failed the college entrance examination and suffered a blow, Xiao Yang was depressed, and he was even more confused when he went to college, but the death of his parents made him wake up, and he began to be angry, and finally got a considerable scholarship every year, and then embarked on the road of entrepreneurship with a series of opportunities.

During that time, the high school and a series of university knowledge were almost imprinted in his soul.

High school knowledge, maybe he will forget, but there is still a lot of college knowledge that is still clear, at this time, holding the high number and looking at it for a while, Xiao Yang only felt very familiar, even if some of the memories that had been blurred, between the flips, they gradually became clearer and clearer.

In the past week, Xiao Yang has been making up for his high school knowledge.

Although a lot of knowledge points have been memorized back, to be honest, although it doesn't seem like learning it all over again, Xiao Yang's head swelled for a while. But now, the situation has changed, and the more complex knowledge of the university has become easier to absorb in front of Xiao Yang.

Relish, really relish.

Even...

"You're really looking at advanced math?"

Hearing this voice, Xiao Yang was taken aback, only to find that he didn't know when, his math teacher was already standing in front of the dormitory table, looking at the advanced math in his hand with interest, and it seemed that the other party should have been standing for a long time.

Xiao Yang's math teacher is named Zhang Shuhan, and Xiao Yang has just transferred to the second class classroom he took Xiao Yang to.

In fact, Zhang Shuhan has always been a little sympathetic to Xiao Yang before, he knows some of the inside story of Xiao Yang's transfer of schools, and understands that Xiao Yang, an honest child, was bullied into Bauhinia High School, so he has actually been very concerned about Xiao Yang, and he has communicated with Su Qing about Xiao Yang more than once in private.

It is precisely because of this that when Su Qing suggested that the teachers tutor Xiao Yang, Zhang Shuhan was the first to agree.

However, when he came to Xiao Yang's dormitory, Zhang Shuhan was actually a little angry, because he saw that Xiao Yang was actually reading a textbook!

The college entrance examination is about to start, and what should be done at this time is to brush the questions frantically, even if you can't write, you should also look at the questions, and look at the questions more to find your own problems. At this time, I was still reading the textbook, either I couldn't keep up with the basics until now, or I heard my footsteps and grabbed it to deal with the teacher.

And a top student who has been transferred from a middle school, will the foundation be even worse?

The answer is obvious.

Immediately afterwards, Zhang Shuhan found that Xiao Yang was not reading high school textbooks, but college textbooks such as advanced mathematics, Zhang Shuhan was not pleased, let alone amazed.

Instead... Getting angrier!

What a senior high school student should do now is to seize the time to sprint for the college entrance examination and prepare for the college entrance examination, instead of reading the university's textbooks while counting the days and waiting for the college entrance examination.

To put it nicely, this is called love of learning.

To put it mildly, it's called putting the cart before the horse.

But just when Zhang Shuhan wanted to question loudly, he was surprised to find that Xiao Yang didn't seem to be pretending, because he saw the kind of abandonment of distracting thoughts and concentrating on studying from Xiao Yang's body, and he didn't even notice that Xiao Yang walked in by himself.

Could he really understand it?

Are you kidding!

Zhang Shuhan was surprised, advanced mathematics and high school mathematics seem to be just a word difference, but they are very different, and the difficulty is definitely not something that a high school student can understand by looking at the textbook of advanced mathematics by himself, but Xiao Yang's expression is completely like understanding the knowledge points inside.

Although it was incredulous, Xiao Yang's expression was not unusual.

couldn't help it, Zhang Shuhan let out such an exclamation.

"Teacher Zhang!"

Seeing Teacher Zhang, Xiao Yang hurriedly got up, a little glad that he didn't pick up a pen and write just now, otherwise the fact that his right hand was fine would not have been exposed.

Facing Xiao Yang, Teacher Zhang's eyes were a little complicated, and he pointed to the advanced math textbook on the table: "Can you really understand this book?"

"Uh... I guess I can understand it. Xiao Yang said modestly.

But his modesty was a little exaggerated in the eyes of Mr. Zhang, and he couldn't help but frown: "You can understand advanced mathematics by self-study?

Xiao Yang scratched his head, shy.

Zhang Shuhan raised his eyebrows and pointed casually: "What are the similarities between maps and functions?"

Whether what he said is true or not, as long as you try it, you will know, Zhang Shuhan did not dwell on these questions, but asked questions directly, and stared at Xiao Yang with his eyes, wanting to see if Xiao Yang could answer.

"Are they the same?" I saw Xiao Yang think for a moment, and then said:

"First of all, mappings and functions are the correspondence of elements in two non-empty sets. ”

Second, the correspondence between functions and mappings is directional. ”

"Finally, the elements in A are arbitrary, and the elements in B are unique: that is, any element in A has a unique element in B. ”

At this moment, Zhang Shuhan was shocked.

This answer is perfect!

And his answer is very clear, after all, this question is not simply asking for some definitions, if you want to answer, you need to really understand the content in order to make such an answer, not something written in a textbook that can be memorized by rote.

Xiao Yang can answer, which means that he really understands!

Talented?

Zhang Shuhan swallowed his saliva, and happened to see the test paper of the last test on the table, and the few questions in front of the paper were all empty, but only the last one was rough, which was full of crooked handwriting.

This question was rated as the most difficult in this math test.

Because this question involves knowledge related to high mathematics, it is very complicated to solve it with high school thinking, so it will make candidates feel difficult. But at this time, Xiao Yang's above solution was extremely concise and powerful, and he directly used the ideas of advanced mathematics to solve it, which was clear and complete!
