Chapter 540

Gao Lan couldn't help taking a breath when she saw the question on the test paper.

Dare not spit out.

She was curious to see how Qin Chen would solve the problem.

"For a highway, team a needs 24 days to repair it alone, and team B needs 30 days to repair it alone. After several days of cooperation between Party A and Party B, team B stopped to rest, and team a continued to repair it for six days."

After reading the title, and then looking at what Qin Chen didn't want, he wrote directly.

Qin Chen used the method of setting the unknown X.

Shea and B repaired for X days.

It is known that it takes 24 days for a to build this road alone, so the efficiency of a is 124.

It takes 30 days for B to repair alone, so the efficiency of B is 130

Add up these two numbers and multiply by X.

Then add the distance repaired in the next six days, which is six times 124.

Because of this problem, Qin Chen assumes that the total distance is unit 1.

Then this equation is listed "(124 + 130) x + 6x124 = 1."

If you follow this equation, you can get that x equals nine days.

Seeing the process written by Qin Chen, Gao Lan was stupid.

She never thought that Qin Chen, a sophomore Chinese undergraduate, could make such a rare test question.

You know, graduate students can't do this kind of problem.

At least Gao Lan will not think of this solution for a moment and a half.

Although she has also studied mathematics as a graduate student, compared with Qin Chen.

It's too far.

Now, Gao Lan believes what Zhao Dabao, a former math teacher, said.

Zhao Dabao said that Qin Chen was a mathematical genius. At that time, he also brought the test papers for Qin Chen at the graduate stage.

Qin Chen finished all the thick papers in less than ten minutes.

At that time, Gao Lan thought Qin Chen had seen this topic before.

In other words, Qin Chen has some talent in mathematics, but she didn't find it before.

But now it seems that Qin Chen has more than a little mathematical talent. He is simply an outstanding demon player.

If Qin Chen has only a little talent in mathematics.

Then those so-called mathematics professors and doctoral students majoring in mathematics are rubbish.

When Gao Lan was shocked here, she found that Qin Chen moved again.

This time Qin Chen didn't do the next problem, but wrote the second solution under this problem.

At first, Gao Lan didn't think so, but after reading the problem-solving process written by Qin Chen.

Gao Lan was shocked and almost didn't come up at one breath.

Qin Chen wrote "(1-6x124) (124 + 130) = 10" in the second method

Qin Chen simply wrote such a formula and came to the conclusion that the answer was nine.

At first, Gao Lan still couldn't understand the test question.

After being stunned for a while, Gao Lan found that stepping on a horse was not a checking calculation?

If someone had told Gao Lan that there are mathematical geniuses in the world, you can learn without a teacher without learning.

Gao Lan will certainly scold this man as crazy and crazy.

Although mathematics is only a basic subject, it is the basis of all knowledge.

For example, if you leave the mathematical calculation method, you can't go on at all.

There are also liberal arts, such as what geography and biology, which also has a lot of calculation content.

For example, what is the equatorial regression line, or biological DNA.

These things need to be applied to mathematics.

Therefore, although mathematics is only a basic subject, it is difficult to master it.

Ordinary people devote themselves to learning for decades, and it is impossible to achieve mastery.

Even a mathematical genius can spend a lot of hard work before he can stand out in mathematics.

But now, Qin Chen has completely broken this natural law.

Because according to Gao Lan, Qin Chen never listens in class.

Either sleep and play games, or skip classes and go to Internet cafes.

A while ago, before the joint examination, Gao Lan also saw Qin Chen go to the Internet cafe to sleep.

But he is such a careless student who doesn't study hard.

How can Gao Lan not be shocked that he has solved a math problem that graduate students can't solve now?

After checking the calculation, Qin Chen also noticed Gao Lan standing next to him.

So Qin Chen stopped writing.

Now there is still an hour before the exam. Qin Chen plans to sleep and then hand in his paper for dinner in advance.

Seeing Qin Chen stop his action, Gao Lan can't help reminding Qin Chen.

You have just finished the second answer. Why don't you do it?

"Can't you do the following questions?"

But it's impossible to think about it.

Like the first two difficult math problems, Qin chenmei frowned and solved them.

Even if the following questions are difficult, I'm afraid they can't beat Qin Chen.

"Qin Chen, you......" Gao Lan swallowed his words.

Because she saw Qin Chen turn over the test paper and put back the test paper she had taken from the corner of the table.

Then he revealed his test paper lying below.

Gao Lan can see clearly that Qin Chen has two test papers of his own.

That is, the joint examination papers at the undergraduate stage and the joint examination papers at the graduate stage are densely written at this time. They are all finished!

Seeing this scene, Gao Lan was encircled again.

Qin Chen didn't do his own thing just now.

But idle and bored, taking the examinee's test paper abandoned by others to do it?

Even other people's papers can make this wonderful check.

Gao Lan can't think of what kind of wonderful solutions Qin Chen can write in his own test paper.

But since Qin Chen can do it, why not let him do all the blank papers?

The city's College Students' joint examination, the examination papers of all subjects are unprecedented difficult.

Even other subjects.

Like what language, English, this kind of pure Mongolian words can still get a little score.

But in the subject of mathematics, candidates can't get it at all.

This method is useless for mathematics, because there are most objective mathematical problems.

Unlike subjective questions, objective questions are what they should be.

Even if there is a difference between a number and a decimal point, it is wrong!

Therefore, mathematics in the previous joint examination was a score pulling subject.

If some students can get more marks in math.

So maybe it can improve the results of the joint examination at the undergraduate stage of Jinling University as a whole?

Gao Lan thought, "I am also a member of Jinling University. If Jinling university is banned because it is at the bottom, where should I go?"

Gao Lan was trained by Jinling University.

University, graduate student and Gao Lan all spent their time in Jinling University.

After graduating from Jinling University, Gao Lan resolutely chose to stay as a teacher.

If Jinling University was banned by the education department at that time, wouldn't it also lose her job?

If so

Gao Lan is thoughtful. Her civic life is constantly flowing and thinking about something.

Just a few seconds
