However, Cai Yong was a world-famous literary scholar. When he encountered a difficult problem in knowledge, he would only ask for advice.
Wu Chulai had also calculated this point. Seeing that time was passing, he was really afraid that Cai Yong would solve it, so he immediately urged him again.
"Lord Cai, can you solve it?"
Liu Fei also frowned at this moment. He felt that this young man was indeed a little too much.
The host had a guest, so if you had any questions to ask, you should wait until the guest had left.
Not only was he not giving face to the host, but he was also not giving face to his guest.
When he heard that this guy's question was only a simple calculation question, Liu Fei immediately raised his head and looked at him.
"Brother, I don't know what kind of math problem you have. I'm not talented, but I know a thing or two about math, so why don't you let me answer it for you?”
Wu Chulai looked at Liu Fei with disdain and ignored him.
He had prepared this question for Cai Yong. What right did a junior who no one knew have to know?
Even if he knew, so what? Could it be that he could calculate it?
Cai Yong's eyes lit up.
Liu Fei actually knew how to count.
Since that was the case, he might as well use this question to test Liu Fei and see if he had really learned from the facts.
Zhang Zhongjing brought Liu Fei to visit him, how could he not know Zhang Zhongjing's intention?
With his recommendation, Liu Fei could rise to the top.
However, if he wanted to get his recommendation, he had to have real knowledge.
He immediately asked the question that Wu Chu had asked before he came.
Student A and Student B went to the shop to buy the same book. Student A used three-fifths of the money he had on him, and Student B used two-thirds of the money he had on him. Student A had five wen more money left than Student B. How much money did Student A and Student B bring with them? How much was the book?
Liu Fei raised his eyebrows. Although he was ignorant and incompetent in his previous life, he still graduated from a pheasant university.
Such a simple math problem was naturally not difficult for him.
Looking at the question, it was a simple linear equation of two variables.
His math wasn't taught by his physical education teacher, so how could he not know it?
Wu Chulai said proudly.
This question was found in the Nine Chapters on Arithmetic.
Not to mention the people who heard this question, even he himself had to calculate for two whole days and two nights before he could solve this question.
Now, even if a young kid could solve this problem, it was really laughable.
Lu Zhi and the others also looked at Liu Fei curiously.
If Cai Yong couldn't calculate it, how could he?
Liu Fei glanced at everyone and smiled.""So Lord Cai is disdainful of this question and deliberately wants to see my ability. Alright, then I will be bold and embarrass myself in front of you.”
Cai Yong was stunned. Could this kid really solve this problem?
However, no matter what, he had a good impression of Liu Fei.
Liu Fei's words just now were obviously to give him a way out and protect his face.
He was not stupid, how could he not know!
Wu Chulai, on the other hand, was laughing non-stop. A little brat actually dared to spout such arrogant words. Hmph, I'd like to see how you're going to clean this up.
"Oh, so this little brother actually calculated it so quickly. I just don't know what the answer is?”
He was afraid that Cai Yong would figure it out if he was given too much time, so he immediately seized the loophole in Liu Fei's words and asked directly.
When the others heard this, they also looked at Liu Fei, waiting for his answer.
Liu Fei shook his head and smiled." Brother, this question is indeed very simple. Alright, listen carefully. Don't forget it after you leave this door. At that time, no one would be willing to explain such a simple question to you for a long time, understand?”
Wu Chulai was stunned, and then he was filled with anger.
He just wanted to push Liu Fei up the ladder, but he didn't expect this guy to be out of breath.
"In that case, I'll listen attentively.”
Liu Fei cleared his throat and said," Listen up. Let's assume that Student A took X wen and Student B took Y wen. Student A, Student B, and Student B bought the same book from the same bookstore, and the price of the certificate is the same. Then we can get three-fifths of X equals two-thirds of Y. If Student A has five wen more money than Student B, then we can get two-fifths of X equals one-third of Y plus five wen.”
"In the end, we came to the conclusion that Student A took fifty wen, Student B took forty-five wen, and the book was thirty wen.”
After saying that, Liu Fei turned to look at Wu Chulai." Brother, am I right?”
In his previous life, any vegetable seller could solve such a difficult question. Why would he use this to test people?
Wu Chulai had racked his brains to come up with this question to buy a book. He had come up with it after imitating the Nine Chapters on Arithmetic. It was to cater to Cai Yong's background as a great writer, so that people would think that he had come up with it on a whim.
This way, people would believe that he could calculate faster than Cai Yong.
He had spent two days and two nights calculating this question, and he had no idea how much paper he had spent before he finally figured out the answer. However, Liu Fei had only listened to it once, and the answer he gave was exactly the same as what he had calculated. How could he not be shocked?
Wu Chulai panicked and shouted,"You, how did you figure it out?"”
Liu Fei looked at Wu Chulai coldly and said,""I told you to listen carefully just now. I'll only say it once. Didn't you listen just now? Or are you sure that I can't calculate it?”
"Eh?"
Lu Zhi and the others looked at each other in disbelief.
Cai Yong's eyes were also wide open, and he hurriedly picked up his pen to calculate again.
With the answer, he calculated quickly and soon came up with the exact same answer. He couldn't help but be shocked."This person's mental arithmetic is actually so amazing, who in this world can compare to him?”
He knew that he definitely could not do it.
"Am I right?" Liu Fei asked again.
Wu Chulai was sweating profusely, no longer as calm as before.
"Yes!"
One word seemed to have drained all his strength, making him feel weak.
He looked at Liu Fei unwillingly." How did you figure it out?”
"This is the mental arithmetic technique taught by Elder Cai. Without Elder Cai's permission, I dare not teach it to anyone else." Liu Fei shook his head. Sigh…It's just that I'm a little slow and didn't learn it well, which is why Elder Cai didn't let me call him 'teacher'. Today, I'm here to ask Elder Zhang Zhongjing to plead for mercy on my behalf. I hope Elder Cai can accept me as a student.”
Zhang Zhongjing, who was at the side, also hurried forward and said,""Elder Cai, for the sake of this young master, please accept my young master. Although he is congenitally deficient, he is exceptionally diligent. He has been locked up all day these days and has only been studying your mental arithmetic method.”
