"Zhang Beining, if you want to say something, just stand up and do it. Why do you need me to answer?" Chen Haoxuan said discontentedly to Zhang Beining.
"Haoxuan, did you forget that I'm not in your class? If I stand up to answer and she sees me, even if I get it right, she might not give me the pen," Zhang Beining explained.
After hearing Zhang Beining's explanation, Chen Haoxuan remembered that she and her friends had skipped class to come here. With no other choice, Chen Haoxuan stood up and answered the question: "The answer is 2 to the power of 6 minus 63 equals 1."
Clap, clap, clap... Yan Mei clapped happily and said, "Good, good! I really didn't expect that none of the students in the class could answer it, but the usually low-key Chen Haoxuan got it right. I truly admire your intelligence. You know? I thought about this for several days before figuring out the answer, yet you came up with it in just ten minutes. I'm impressed! Can you tell me how you thought of it?"
"Wow—so this math problem is that difficult," the students in the class exclaimed.
Chen Haoxuan shrugged and said lightly, "I don't know why; I just knew it as soon as I saw it."
"I know! It's because you're a genius," Yang Lin joked.
"Exactly! I see you as a genius. This isn't an answer that just anyone can come up with, especially not in such a short time," Yan Mei said excitedly. She felt honored that her student had surpassed her; it was something to be proud of.
While others wanted compliments, Chen Haoxuan was different. He directly spoke up, "Teacher, didn't you say that whoever answers correctly would get the pen? I got it right now; can you give it to me?"
"Right, right! Look at me; I almost forgot. Come up and get it!" Yan Mei said with a kind smile.
Chen Haoxuan was not polite; he walked up to the podium, took the pen, thanked her, and turned back to his seat.
He didn't even look at what the pen looked like. As soon as he returned to his seat, he handed the pen to Zhang Beining and said, "Here, this is the pen you like."
"Thank you," Zhang Beining said happily as she accepted the pen that Chen Haoxuan handed her.
"Wow, what a beautiful pen! The color is so dark it shines, and the elegant body has a golden clip," Zhang Beining exclaimed. After admiring it for a while, she turned to Ma Yichen and said, "Look at Haoxuan, he’s so manly! I said I liked it, and he just got it for me. And you! Hmph, still calling yourself a genius young master, what nonsense."
"Don't say that about Ma Yichen. It's not that he can't answer; it's just that he didn't have enough time. If you give him about a day, I can guarantee he will come up with an answer," Chen Haoxuan defended Ma Yichen.
"Buddy, true buddy, you are really my good friend," Ma Yichen said to Chen Haoxuan, giving him a thumbs up in gratitude.
Chen Haoxuan wanted to continue chatting online, but Yan Mei wouldn't let him off the hook. She wanted to test Chen Haoxuan further to see just how capable he was.
Chen Haoxuan didn't want to answer Yan Mei's questions, but she insisted that he stand up and respond. As a student in school, teachers are like parents; he had to listen to them. To keep the conversation going, Chen Haoxuan answered quickly, basically responding immediately whenever Yan Mei posed a question.
Yan Mei completely forgot she was in class; she became increasingly interested in Chen Haoxuan. She asked him all the math problems she had previously found difficult, and Chen Haoxuan did not disappoint her—he got them all right.
Twenty minutes later, Chen Haoxuan grew impatient. He felt that Yan Mei was determined not to let him go and was bound to ask him a math problem he couldn't solve.
If Yan Mei asked Chen Haoxuan to explain his calculations step by step, he might struggle because he wasn't very familiar with 21st-century knowledge. However, he could discuss knowledge from the Future Century; the question was whether Yan Mei and the others would understand it.
Chen Haoxuan spoke up to Yan Mei, saying, "Teacher, you've asked me so many questions; I should have the right to ask you one too!"
"Of course! Go ahead!" Yan Mei replied excitedly. She had a blind passion for mathematics; the harder the problem, the more she enjoyed it. So she was eager to see what kind of math problem Chen Haoxuan would come up with.
"There are three people who go to stay overnight; it costs 30 yuan for one night. Each person contributed 10 yuan to make up the total of 30 yuan paid to the Boss. Later, the Boss said there was a discount today and only 25 yuan was needed. He took out 5 yuan and ordered the waiter to return it to them. The waiter secretly kept 2 yuan and then distributed the remaining 3 yuan among the three people, giving each person 1 yuan back. Initially, each person paid 10 yuan; now they got back 1 yuan each, which means they effectively paid 10 - 1 = 9 yuan each. So for three people paying 9 yuan each: 3 x 9 = 27 yuan. Adding the 2 yuan kept by the waiter makes it 29 yuan. Where did the extra 1 yuan go? Please answer!" Chen Haoxuan said with a mischievous smile.
This math problem had caused a huge stir in modern society in Chen Haoxuan's previous life; he had come across it while reading history books and remembered it.
"There are three people who go to stay overnight; it costs 30 yuan for one night..." Yan Mei began to ponder.
The students in the class were also thinking about Chen Haoxuan's math problem.
Just a minute or two had passed when Yan Mei spoke up. Chen Haoxuan thought she had come up with an answer so quickly! To his surprise, Yan Mei hadn't figured it out; she had forgotten the math problem.
"Chen Haoxuan, could you repeat the question?" Yan Mei asked awkwardly. She had just posed the question verbally, and Chen Haoxuan had answered all of it. Yet now, when he posed the question, she had completely forgotten it, which made her feel quite embarrassed; she was almost too shy to call herself a teacher.
"There are three people who go to stay overnight, and it costs 30 yuan for one night. Each person contributed 10 yuan to make up the 30 yuan..." Chen Haoxuan repeated.
To avoid forgetting, Yan Mei wrote down the math problem that Chen Haoxuan had posed on the blackboard. The students in Class Eight also began to copy the problem down to calculate it.
As Yan Mei read aloud, she wrote on the blackboard: "They took out thirty yuan and gave it to the Boss. The Boss gave five yuan to the waiter, who hid two yuan and returned the remaining three yuan to the guests. Each of the three guests received nine yuan back, totaling twenty-seven. Adding the two yuan hidden by the waiter makes twenty-nine. So... where is that extra one yuan?"
"Yeah! Where did that extra one yuan go?" The students in the class became confused; they all felt that this math problem was strange. They could calculate it easily, but the answer they arrived at was clearly wrong. They started with thirty yuan, but their calculations only added up to twenty-nine, missing one yuan.
"Has anyone figured out the answer?" Yan Mei asked the students in the class.
"No, our calculations all come up short by one yuan, and we don't know why," a female student exclaimed loudly.
