My World is All Experience

Chapter [-] How to Make Yourself Rely on Differences (Part [-]) Third Update

It wasn't that he couldn't write it, and it wasn't that the questions in front of him stopped him. In fact, he already knew all the answers to these questions the moment he stared at them.

However, as he said, he couldn't go on, and he couldn't go on.

He is a scumbag now, a real scumbag. If he gets a perfect score in the exam, it will be a big joke, although this will undoubtedly give him a lot of sense of accomplishment.

But apart from this, I can't get anything, but it is very likely that I will make myself a mess.

And this is definitely not his idea or imagination, but the reality that is likely to happen.

For example, as a scumbag, how did he get full marks on the exam? This is inexplicable. It is impossible to say that he suddenly became enlightened, or that he has been hiding his strength, such a liar.

Explanation, there is no explanation at all, and the teacher does not have the interest to listen to his explanation. The only outcome is to find him cheating, and once he thinks cheating, the trouble is also not small.

Obviously he didn't need to get himself into that kind of troublesome situation, especially since he was kicked out of No. [-] Middle School and was not a student of No. [-] Middle School at all, even more so.

Thinking of this, Jiang Chen looked at the ten questions he had already done. After hesitating for a while, he directly applied the pen on most of the questions. That's right.

The second answer was also filled in again, but this time he filled in almost all wrong answers. Of the ten questions, he only kept two correct. After all, the multiple-choice question is completely correct for both. Cats can also run into dead mice, and they can always get a few right, ten to two. This is not a big surprise.

It's just that multiple-choice questions can do this, and fill-in-the-blank questions cannot.

However, Jiang Chen naturally wouldn't be a problem with this. He directly selected a few and filled in the correct answers during the circulation of the answers.

Anyway, he basically did this in the past, but in the past, it would not be done, and at this time, it was just to avoid writing the correct answer by himself.

So much so that Jiang Chen's expression couldn't help but show a slightly strange color when he was writing with a fountain pen. He really never thought that he would have such a day, that he would despise himself for being too good at answering questions.

However, this strange look didn't last long, because even if I had to estimate my level to answer the questions, the test paper came to an end very quickly, and at this time, even the third class had not been lost. .

This situation was a little embarrassing, and Jiang Chen didn't even know what to do for a while.

This is not only the time left for the third class, but also the closing time, plus the fourth class. During this period, he cannot turn the book, otherwise the result will be unpredictable.

Under such circumstances, he seemed to have nothing to do at this time.

With a slightly speechless expression, Jiang Chen looked at it and tried to find something to pass the time, but it was obvious that he had nothing to use. Now that he has obtained the system, he has no interest in listening to music, and because of his physique, even if he is sleeping, he is unlikely to fall asleep at the moment.

As his eyes wandered, in the end, his eyes were fixed on the test paper and the few pieces of white paper next to him.

He accidentally brought these blank papers from home, and they were caught in the test papers. He didn't see them at the time, so he came all the way in the morning. After finding them, he found that they were basically blank, and Jiang Chen didn't throw them away. Yes, it is placed directly on the table.

At this time, he looked at these white papers, his eyes couldn't help but flicker, his heart suddenly moved, and his right hand also pulled out an idiot and placed it on the test paper.

And the eyes are once again looking at the questions on the test paper.

He really has no way to pass the time now, but he also seems to have a way that is not the way, that is to do these questions again, it is really not good to do it on the test paper, but if it is done on white paper, it will not be What's the problem, and Jiang Chen reckoned that if he was full, he might be able to increase his experience points a little bit, although it couldn't be too much, that is, one or two points, but it could be considered to be a waste of time, and there was still more than one class left. time, if you don't find something to do, it won't be that simple.

And thinking of this, he quickly started to act, and while waving the water pen in his right hand, one by one formulas appeared at this moment, and at the same time, his eyes were fixed on the topic.

Countless information flows, and the answers to the final questions are also reflected on the white paper, but compared to the regular answers, Jiang Chen at this time is in order to pass the time, no, it should be said to delay the time, his this time The answer is different from the normal situation. Almost every kick he answers is answered in more than one way, but in every way he can think of, which is absolutely terrifying.

Chapter [-] How to make yourself rely on the difference (continued) (fourth more)

已知集合A=R，B={(x、y)︱x、y∈R},f是从A到B的映射fx：→（x+1、x2）,（1）求2在B中的对应元素；（2）（2、1）在A中的对应元素?

解析：（1）将x=2代入对应关系，可得其在B中的对应元素为（2?+1、1）；（2）由题意得：x+1=2,x2=1?得出x=1，?即（2、1）在A中的对应元素为1

.

Prove: ab is divisible by a^nb^n

Let ab=k, then a=b+k

a^n=(b+k)^n=b^n+,1)*b^(n-1)*k+,2)*b^(n-2)*k^2...+k^n

所以a^n-b^n=,1)*b^(n-1)*k+,2)*b^(n-2)*k^2...+k^n是k的倍数

That is, there is ab that can divide a^nb^n

.....

Jiang Chen's movements were extremely fast. While waving the tip of his pen, several blank sheets of paper had already been filled on his test paper, and countless problem-solving methods appeared on the blank sheet.

And he also occasionally thought of a series of system prompts.

"Ding, congratulations on completing the exercises and getting math experience +1!"

"Ding, congratulations on completing the exercises and getting math experience +3!"

"Ding, congratulations on completing the exercises and getting math experience +1!"

...

Among the mixed voices, what surprised Jiang Chen was that he didn't have one experience point per page, and a question had at least one experience point. If he was lucky, he even had three, or even five experience points.

It's just that he only has experience points if he has complete problem-solving steps. There is no way to write the answer directly. More importantly, a problem is not only a chance to gain experience, as long as he can make a variety of different The way of solving the problem can get one point, there is almost no upper limit, as long as he can solve it.

Under such circumstances, for Jiang Chen, it was definitely a surprise. After all, he just didn't have time to kill. Under such circumstances, he had more fun in his time.

And time passed slowly inadvertently, and the bell rang again, and soon it was the third time, which also announced that this exam was gradually coming to an end.

Jiang Chen also stopped to write, instead of paying attention to his achievements, he looked at his attributes.
