"Haha! Your question is not difficult. First of all, we still have to replace it with x, which represents rabbit."
"Then we can get another formula, x plus x minus twice five, equals thirty-five."
"From this formula, let's do another conversion, that is, x plus twice x minus ten, equals thirty-five."
"That is, three times x is equal to forty-five. It follows that x is equal to fifteen, and the number of chickens is twenty-five."
Lin Fan once again easily obtained the answer through the equation.
Xing Fengchu was shocked at the time. He carefully calculated in his mind and found that the answer was also correct. Xing Nian'er on the side saw her grandfather being stumped and pouting, and was very angry.
Lin Fan smiled and said: "Senior, are you convinced this time?"
Xing Fengchu said with a smile: "Haha! I'm convinced. I'm really convinced this time. Little brother, your research on mathematics is unmatched by this old man."
After hearing this, Lin Fan said in a deep voice: "Senior, you are joking. It's not that the junior's research in mathematics is higher than yours, but that you don't know how to keep pace with the times."
"Besides, what I just used was an equation for calculation. As long as you master the equation, even a three-year-old child can easily solve problems like a chicken and a rabbit in the same cage."
oh!
Hearing what Lin Fan said, Xing Fengchu was extremely shocked. Could a three-year-old child also solve such a difficult arithmetic problem?
"Little brother, please don't deceive me. I have studied the art of Qimen Dunjia. This arithmetic is the basis. I have been studying it for many years, but I haven't figured out why."
"If there is really such a method that can allow children to master such complex problems, then if the old man masters it, wouldn't he be able to study more things?"
Xing Fengchu said in a deep voice.
His eyes were full of disbelief, but in his heart he was very much looking forward to it. After all, he studied the art of Qi Men Dun Jia, wasn't it just to be able to study stronger Qi Men Dun Jia.
And mathematics was the stepping stone for him to develop a stronger Qi Men Dun Jia.
"Haha! Senior, what I said is not exaggerated at all. You have also seen the substitution formula for x and y. Do you find it difficult?"
Lin Fan asked with a smile.
Xing Fengchu was stunned for a moment and said: "It's not difficult!"
"If it's not difficult, is my logic difficult?"
Lin Fan asked again.
"It's not difficult either!"
Xing Fengchu replied.
"Haha! Since it's not difficult, why can't children master it?
In fact, with the advancement of the times, many things can be solved in simple ways."
"For example, the circumference of a circle does not have to be measured point by point. We only need to find the diameter of the circle, which is the width of the circle, and multiply it by three point one and four to get the circumference of the circle.
long."
"If you want to get the area of a circle, that's half the width of the circle times half the width, and then multiplied by three point fourteen, that's the square of the circle."
Lin Fan said with a smile.
Xing Fengchu immediately calculated it in his mind and found that it was exactly the same as the areas of some circles he had previously calculated. This kid's method was too simple.
"Boy, how do you know this?"
Xing Fengchu asked in shock.
"Haha! I discovered these by accident. For many things, it is not the more complicated the better, but the simpler the better."
Lin Fan said with a smile.
Xing Fengchu was stunned. Zhao Dashan on the side saw that the time was right and said in a deep voice: "Senior Xing, this is none other than the current Crown Prince."
What!
It’s actually His Royal Highness the Crown Prince!
Xing Fengchu immediately stood up and was about to kneel down. Lin Fan hurriedly stopped him and said with a smile: "Senior Xing, you can't give me such a big gift. I'm here to see you this time because I hope you can do me a favor."
Xing Nian'er, who was on the side, heard that Lin Fan was the prince and was so polite to her grandfather. She immediately looked at Lin Fan and her eyes became much gentler.
Xing Fengchu said in a deep voice: "His Royal Highness, whenever necessary, I will be at your disposal."
At this time, Xing Fengchu was filled with admiration for Lin Fan. He was able to conquer and fight well, and he could also have such attainments in Qimen Dunjia.
"Senior Xing is joking, I have no intention of sending you. I want to build a university, and I hope you can be the dean of the university."
Lin Fan said in a deep voice.
"University?"
Xing Fengchu looked confused.
"That's right, it's a university. From now on, anyone who wants to take the imperial examination will have to graduate from a university, and to enter a university, you will also need to pass various examinations."
"What I want to host is not one university, but many. Senior Xing, would you like to serve as the dean of one of the universities?"
Lin Fan said in a deep voice.
hiss!
After hearing this, Xing Fengchu took a breath of air-conditioning. Is His Highness the Crown Prince going to shake things up?
Some time ago, the meritorious service of Literary Scholar was revoked, which caused a big fuss.
What kind of universities are being opened now, and only those who have attended university are eligible to take the imperial examination. Doesn't this mean that the threshold for the imperial examination has been raised!
wrong!
By doing this, His Royal Highness the Crown Prince has fundamentally solved the problem of the symbiosis between officials in the DPRK and China.
You know, in the previous imperial examinations, if a candidate's teacher was an official in the court, it would be much easier for him to pass the imperial examination.
And if a candidate's teacher is unknown, it will be difficult for him to pass the imperial examination.
If His Highness the Crown Prince does this, then the candidates who graduate from the university will have no teachers, and they will naturally have to rely on their own abilities when taking part in the imperial examination.
Thinking of this, Xing Fengchu said in a deep voice: "Your Highness, this university must be very important. Is this old man capable of serving as the dean?"
After hearing what Xing Fengchu said, Lin Fan smiled instead and said: "Senior Xing, if nothing else, your research on Qimen Dunjia alone is enough to serve as the dean."
"This... Your Highness, you are joking. Qimen Dunjia is just a trail."
Xing Fengchu looked ashamed.
"Senior Xing, have you seen the big truck of Shunlu Express Company?"
Lin Fan asked.
Xing Fengchu nodded and said: "I dare not hide it from His Highness the Crown Prince. I have indeed seen that big car and was very surprised by it!"
"Moreover, I bribed the employees of Shunlu Express Company and secretly looked at the structure of the big truck. I found that the structure is surprising. There are many places that I could not have imagined."
kindness!
Lin Fan was slightly shocked when he heard what Xing Fengchu said. He just couldn't understand some of what Xing Fengchu meant, but he could understand most of it.
correct!
He has mastered the art of Dunjia, and he must know more about machinery and gear transmission than anyone else. If he can't understand it, then no one can.
