Li Yuhang was completely stunned.
Growing up, he was considered a top student and often participated in competitions and so on.
If he hadn't performed abnormally in the high school entrance examination, he would be in an intensive class now.
However, what Lu Fan said had a huge impact on him.
First, you can see the correct answer at a glance, and then apply a few related formulas. Is the question solved?
What kind of cool operation is this?
Li Yuhang has a feeling that although I don't understand what he is talking about, I still feel that it is very powerful.
His mother is not so easy to fool.
"It sounds like it's true. Who do you want to deceive? Who knows if you just took a peek at the correct answer and then pretended to be here!"
It is simply a fantasy that the correct answer can be seen at a glance, and she does not believe it at all!
"Low IQ limits your imagination." Lu Fan glanced at her, then turned to look at Li Yuhang.
"Have you figured it out?"
"I seem to understand a little bit, but I don't seem to understand a little bit." Li Yuhang's expression seemed a little painful.
He vaguely felt that the method Lu Fan mentioned seemed to be really useful.
Anyway, the steps for solving big questions in science are to first list the formulas, and then substitute the numerical values to calculate the correct answer.
Many people don't know how to solve the big questions, so they just write down a few formulas to get some points.
What Lu Fan said is to first find the answer and then write down a few formulas. It is indeed a very simple method that can save a lot of time in solving questions.
However, the prerequisite for using this method is that you must be able to see the answer at a glance!
Who can see the answers to all the big questions at a glance?
Li Yuhang thinks this is a very unrealistic thing. He thinks he is very good in physics, but even for normal questions, he can rarely see the correct answer at a glance, let alone these Olympiad questions. .
"It seems that your IQ is not as high as you think." Lu Fan said with a half-smile.
Li Yuhang's face immediately turned red, all the way to his neck.
The reason why he blushed was because he felt that this method seemed to be really useful, but at his level, it seemed difficult to use this method.
If he thought this method was complete nonsense, he would definitely not blush.
Li Yuhang’s mother quits.
If Lu Fan simply said that her IQ was not very good, she wouldn't be too angry.
But her son is her darling, and she has always been proud of it. She has always felt that her son is one of the smartest people in the world.
Now that her son is being said to have a low IQ, this is absolutely intolerable to her.
"What nonsense are you talking about? Do you think you can deceive us with these little tricks? Let me tell you, it's impossible! This is just a trick! We won't believe it at all!"
Li Yuhang's mother was like an irritated hen, glaring at Lu Fan, with the intention of rushing up and scratching Lu Fan if she disagreed with him.
"I lied to you? What's the benefit?" Lu Fan sighed.
He was originally too lazy to explain to the two women, but when he saw his dumbfounded sister, he thought it would be better for him to explain it again.
At least my sister must accept all this!
"If you don't believe that I didn't read the answers, you can test me by randomly finding questions in this exercise book and see if I can spot the correct answer at a glance. Or you can find other exercises, I don't care."
Lu Ling was indeed confused.
From the bottom of her heart, she felt that she should trust her brother.
That was her brother, the brother she had always trusted since childhood, and she had no reason to doubt him.
However, the method Lu Fan said was too difficult for her to accept.
Can you tell the correct answer at a glance?
So what does it mean that she can't figure out the answer for several hours?
It's just too unbelievable.
Faced with other people's doubts, Lu Fan could ignore them.
Anyway, others can't do anything to him, and they won't let him miss a bowl of rice.
But if his dearest sister also had doubts about him, that was something Lu Fan would never want to see.
Therefore, when he saw the doubtful look on his sister's face, he decided that no matter what, he must prove his ability.
What's more, such a simple thing requires no effort at all and is easy to do.
Lu Fan directly placed the Olympiad question book in front of Li Yuhang, indicating that the boy could find some questions to test him out.
Li Yuhang hesitated for a moment, and then opened the question book. As a top student, even if he wanted to test others, he had to pick out a few decent questions.
He looked at it for a while and found a few questions.
These questions were all questions he had studied and felt that there were many detours in the process of solving them.
You can figure out the correct answer to a straight-forward question at once, but you can't figure out the answer to a winding question at once, right?
Of course, due to limited knowledge, the questions Li Yuhang picked would definitely not be the most difficult ones. These questions were already the most difficult ones among the knowledge he currently had.
Li Yuhang felt that it would be amazing if Lu Fan could easily see the answers to these questions at a glance.
"These questions?" Lu Fan glanced at the questions Li Yuhang found, and then laughed, "These are all knowledge for the first year of high school. Are you sure you want to test me with such simple questions?"
"Are you afraid?" Li Yuhang's mother couldn't stand Lu Fan's contempt for her son, and couldn't help shouting again.
"What's wrong with the questions for the first year of high school? You can't do the questions for the first year of high school, so what questions are there for the second and third years of high school?"
"I currently only have the physics knowledge for the first year of high school. I can only rely on you within the scope of my knowledge." Li Yuhang was quite honest.
"Okay." Lu Fan nodded, and then looked at the question.
Because physics questions have to describe a lot of things, each big question is generally not very short, at least one hundred and eighty words long.
Lu Ling also moved over, wanting to follow his brother and try to see if they could solve the problems together.
Although she also knew that with her level, she would definitely not be able to help, but she still wanted to do her best.
No matter what, she is on her brother's side.
However, the result would always disappoint her.
Lu Ling wanted to do her part, but she found that it was difficult for her to do so.
For a 100-word question, it would take her a minute or more just to read it and understand the question. However, before she finished reading the first line, Lu Fan had already reported the answer and started to read the second question.
