Liuye took the pen and paper, sat on the edge of the bed, and quickly entered the problem-solving state.
She hasn't done math problems in so many years, so she needs to take a good look at her memories.
Zhao Jingsong on the side didn't even look at Liu Ye. He just picked up the mathematics textbook Liu Ye put on the bed and flipped through it.
Obviously, he didn't think Liu Ye could solve this problem at all.
His teacher said that in this year's college entrance examination, this was the penultimate math question and it was very difficult.
I heard that none of the seniors and sisters in the school who took the exam could give a complete answer.
At most, it can only answer the simplest first question.
Before the summer vacation, the math teacher specially left this problem to them, but did not explain it to them.
The teacher made this question a summer homework and asked everyone to take it back and do it.
It’s just to exercise everyone’s thinking skills.
As a young math whiz, Zhao Jingsong likes to challenge math problems on weekdays.
Solving a mathematical problem always makes him feel extremely happy.
From the moment he copied this question, he tried to answer it.
However, no matter what he thought, he almost broke his head and couldn't think of a solution to the problem.
It has been a week since summer vacation. During this week, he will take out this question again every day, look at it and think about it.
However, even if he racked his brains, he still had no clue.
Who knew, Liu Ye would see this question today.
He had been working on it for so long and still couldn't figure it out. He didn't think Liu Ye could answer it.
However, soon, reality dealt him a heavy blow.
Just when Zhao Jingsong had flipped through one-third of his math book, Liu Ye's happy voice rang out.
"finished!"
Zhao Jingsong suddenly raised his head and looked at Liu Ye, his eyes full of shock.
Then, he glanced at the alarm clock on his desk. It had been less than ten minutes since Liu Ye started doing the questions.
How is this possible?
I did a math problem that I had not solved for more than a week, and Liuye solved it in less than ten minutes.
Zhao Jingsong didn't believe it at all.
My cousin must have written it randomly!
Zhao Jingsong couldn't find a reasonable explanation, so he had to think this way.
However, when he saw the answer written by Liu Ye at the bottom of the white paper, he was so surprised that he was speechless.
The answer is exactly the same as the teacher’s answer!
Zhao Jingsong's math teacher gave the correct answer when he left the question.
However, the idea of solving the problem is not mentioned at all.
Now the answer calculated by Liu Ye is exactly the same as the answer given by the teacher.
This shows that Liuye has really solved this problem.
"How is this possible?"
Zhao Jingsong stared straight at the delicate handwriting written by Liu Ye and muttered to himself in disbelief.
"Why is it impossible? I told you, I can really do it, tell me, is this answer correct?"
In front of Liu Ye, who has been "tortured" by math problems, such a question is completely trivial.
Isn't it just a geometry question? It's not difficult at all.
"The answer...is right..."
Zhao Jingsong stared at the answer, his words seemed to be squeezed out from between his teeth.
Then, he started from the beginning again and carefully looked at every word written by Liu Ye.
"This...how can you use such a method?"
After seeing the second line, Zhao Jingsong couldn't stand it anymore.
Because Zhao Jingsong had never seen the method used by Liu Ye.
It was obviously a geometry question, but Liuye used the method of algebraic question.
"Why can't I use this method? Didn't I get the correct answer using this method?"
Liuye spread his hands and answered nonchalantly.
I didn't feel the shock in Zhao Jingsong's heart at all.
"Cousin, when doing geometry problems like this, you should draw auxiliary lines and then use geometric knowledge to perform calculations."
Zhao Jingsong frowned and argued.
"You think too narrowly. Who stipulates that geometric methods must be used to make geometric objects? The algebraic method can also be used to solve the problem, and it is simpler. If you go to draw auxiliary lines, you have to draw several lines! It is better to directly mark
Put it into a coordinate system, it’s simple and clear!”
When Liuye was in high school, the methods taught by teachers were much richer than those taught by teachers today.
Which method students choose to use is their own choice.
For Liu Ye, analytic geometry is obviously much simpler, so why bother to draw auxiliary lines for yourself.
Every time Liu Ye said another word, Zhao Jingsong became more shocked.
He took a deep breath, calmed down, and read Liu Ye's problem-solving method carefully.
Only then did I realize that this method is indeed simpler and faster.
It can even be said that there is no need to use your brain at all, just follow the given method and do it step by step.
"Cousin...you are so smart!"
At the end, Zhao Jingsong had nothing to say, only sincere praise for Liu Ye.
"This is nothing, nor is it a problem."
Willow Ye said nonchalantly.
I think back then, she had to answer several real math questions a day!
Questions like this are simply not too easy.
"Cousin... this question... is the second to last question in this year's college entrance examination mathematics! It's worth twenty points..."
Zhao Jingsong, who was shown off by Liu Ye, told the truth with a bitter look on his face.
"What? Can such a question also appear as the penultimate question?"
Liu Ye suddenly felt that mathematics in the 1980s should be very simple.
"Do you have a final question? Show me!"
Liu Ye became interested and wanted to take a look at the last big question of mathematics in this year's college entrance examination.
In Liuye's era, being able to complete the last big question in mathematics was "the god of learning".
Even math teachers may not be able to answer it quickly.
After listening to Zhao Jingsong's words, Liu Ye suddenly gained confidence.
Maybe she can successfully solve the final question.
"Yes! I'll find it for you right now."
As the math representative of the class, Zhao Jingsong had already asked the math teacher for the final question of this year’s math.
Originally, he wanted to solve it with his own intelligence and impress his teachers and classmates.
However, it turned out that this was entirely his overthinking.
He couldn't even understand the question.
Now that Liu Ye was asking, Zhao Jingsong suddenly wanted to know if Liu Ye could answer the last big question.
Zhao Jingsong took out a clean white paper from his schoolbag.
The piece of paper on which the geometry questions were written just now is full of pencil marks that were written on and then erased. One look at it shows that the questions are often done.
There is no trace of writing or drawing on this piece of white paper, which shows that Zhao Jingsong simply does not know how to start solving this problem.
