Fang Chao's ability to achieve his own level of mathematics allowed him to easily cope with the content explained by the four professors, because most of his knowledge points were still in the teaching scope of high school, and a small part involved the content of the university, but for Fang Chao, it was not a big problem.

The mathematics level of lv3 is already equivalent to the mathematics level ability of a junior university.

But if the professor talks about something more advanced, I'm afraid that Fang Chao won't be able to absorb it.

"It's a little difficult...... In the past seven days, I can only understand about seventy percent, and as for the remaining thirty percent, it is really one or two big ones, and I don't have any clue. ”

"The cuneiform script is given, and I don't know what this thing is, but when the professor talks about it, he gets more and more excited, as if he has reached his point, and he doesn't see if we can understand it."

"Didn't you hear what Senior Brother Shen Lang said, professor's words, only allowed to listen, not to speak, whether you can understand or not is your business, but if you don't understand, shouldn't you just ask questions?"

"Do you understand?"

"I barely understood."

Some of the players spoke.

"I didn't expect the training content of the training camp to be like this, if the knowledge points can't keep up, it will be cool soon."

"Zi Zhan, how are you doing in the past seven days, do you understand the content of the next seven days?"

When Xiao Zizhan heard this, he replied, "It's okay, it's not particularly difficult, but the points mentioned in it are indeed very beneficial, and this trip to the training camp is worth the trip." ”

"Zhang Tiannan, what about you?"

"Me"

Zhang Tiannan said with a smile, "There are only one or two points that I don't understand, I immediately consulted some seniors after I went back, and I understood, there is no problem now, but I see that this time the CMO full score champion Fang Chao came up with a smile on his face for seven days, and he wanted to harvest above us, I really envy such a person, who is naturally sensitive to mathematics and born to learn mathematics." ”

"You're so optimistic about him"

"What is the strength of me and Xiao Zizhan, the second and third places in the national finals, but even we can't get a full score in the national finals, and there is no way to hand in the papers in advance, he Fang Chao did it, so he is really strong."

"In mathematics, there are no more than two people who dare to pretend to be forceful, one is a fool, and the other is a real awesome, do you think the person who gets the perfect score in the CMO event will be a fool?"

……

The eighth day of the training camp.

"The professor's course is over, what are we going to do next?"

"Senior Brother Shen Lang, we can't see Senior Brother Shen Lang, where did he go?"

"We're not going to continue today."

"But you don't need to do any questions?"

"That's right, if you just keep explaining theoretical knowledge, without practice, then the level will definitely not be able to really improve."

“……”

At this time, outside the multimedia, Shen Lang walked in with a stack of rolls in his hand and a smile.

"Good morning, juniors." Shen Lang smiled and greeted the sixty-three top students in the entire class.

Shen Lang's smiling appearance made everyone smell an unusual breath.

When things go wrong, there must be demons.

On weekdays, where would Shen Lang smile like this and he was still holding a pair of scrolls in his hand, it was obvious that Shen Lang's appearance today was definitely with a special meaning.

"Senior Brother Shen Lang, are we starting to do the question today?"

"Senior Brother Shen Lang, where is the scroll in your hand?"

"Are you finally going to start working on the question today?"

“……”

Shen Lang still had a smile on his face, and then said, "The master led the door, and the practice relied on himself, after these seven days, I think everyone has benefited a lot, at least there should be great progress in mathematics, and it is not easy to invite those professors to give lectures, so today is the time to check your results, I have a test paper in my hand, a total of twenty questions, all of which are short-answer questions, you only have half an hour, and I will collect all the papers after half an hour." ”

"Ahh

"No, it won't"

"Half an hour for 20 questions"

"Come on, come on, my big knife has already quenched my thirst!!"

"I feel that these twenty questions are very perverted, maybe they will be over!"

"I used to like Senior Brother Shen Lang's laughter very much, after all, laughing is really infectious, but now I'm a little afraid of him laughing, every time he laughs, I feel ill-intentioned, just like today."

At this time, Shen Lang continued, "Everyone is a mathematical genius from all over the country, and a large part of them have been escorted by prestigious universities, so I believe that you also have your own arrogance, I hope that you will rely on your own real skills to solve these twenty questions, rather than stealing chickens and dogs, of course, if I find out, then I'm sorry, please leave this training camp!" ”

"Okay, now hand out the test papers, remember, you only have half an hour."

Soon, all 63 contestants in the math competition got the test papers.

The moment they got the test papers, many people's expressions changed.

"Damn, I knew it was like that!"

"What a simple question!"

"It's just the devil, it's good to be able to solve ten questions in half an hour with these questions, and if you can exceed ten questions, I'll lose ......"

"What now"

"What else can I do can only do hard, how much can I do."

"I guess this should be the first round of screening, I'm afraid I have to exclude some players in this ranking."

"The national team needs absolute elite, and only six of the 63 people can represent the national team, so many of us may not even be able to stay in the last month and go back to our respective provinces."

“……”

Fang Chao was stunned for a moment when he got this test paper, it was a bit interesting, quick calculation and logical thinking......

Very good!

It's out of the low-level fun!

Fang Chao didn't even think about it, and directly started to do the question.

Question 1:

Let i be an imaginary unit, a and b are positive integers, and 丨(a+1)(2+i)丨=丨(b-i)/(2-i)丨, then a+b=

Just by taking a look, Fang Chao instantly came up with two answers, A and B.

But because the title has already stated, both a and b are positive integers.

So a=1, b=7.

a+b=8。

It only took Fang Chao thirty seconds to write down the answer to the first question.

It's simple, it's stress-free.

no problem！

Question 2:

Let a∈r, if both (x2+ax-5)(ax-1) ≥ hold at x>0, then a=
