Chapter 34: That Wonderful Feeling!

  "Then teach me how to use these symbols to solve the problems I've thought of." The woman said calmly, her commanding tone seeming to make it a given that Lin Feng would instruct her.

  Lin Feng couldn't help but let out a bitter laugh. "Can't you use a softer tone? You're asking for advice, after all!"

  "A gentle tone?" The woman furrowed her eyebrows again, looking at Lin Feng with some confusion, shook her head and said straightforwardly, "What kind of tone is that? I don't know!"

  When she said that, Lin Feng couldn't help but cover his face in silence. You're kidding me, you don't even know this? I really don't know if you have any feelings left. In response, Lin Feng could only say helplessly, "Then at least tell me your name! I still don't know what it is.

  The scene fell silent for a moment.

  "Shen Leng Xin." A cold and clear voice came from beside Lin Feng's ear.

  It's really cold!

  "Alright, I'll call you Leng Xin then. The symbols I used to solve the problem today are what I call unknown numbers, used to represent things that we don't know yet. Then, based on the meaning of your question, I will solve the problem." Lin Feng took the paper from Shen Leng Xin's hand and pointed at the symbols.

  "Unknown number?" Shen Lengxin heard Lin Feng say this and asked again, "What does this have to do with you answering my questions?"

  "For example, in the first question, Xiaohai said to Xiaobing: 'When my age is your current age, you were only 4 years old.' Xiaobing said to Xiaohai: 'When my age is your current age, you will be 61 years old.' What are Xiaohai and Xiaobing's current ages?"

  "I first assume that Xiaohai and Xiaobing's ages are already known, assuming Xiaohai is x years old and Xiaobing is y years old. We know that the difference in their ages will not change with time, so subtracting x from y gives us the number of years they differ by, which I represent as x - y using a minus sign."

  "Xiaohai said to Xiaobing: 'When my age was your current age, you were 4 years old.' From this, we can infer that Xiaobing's age minus the difference in their ages equals 4. This gives us an equation: y - (x - y) = 4, which I represent with an equal sign."

  "Then, from Xiaobing to Xiaohai said: 'When my age is your current age, you will be 61 years old.' From this question, according to the representation method just now, we can also get another equation, x + (x - y) = 61. Combining these two equations, I calculated that x = 41 and y = 23, so Xiaohai's age is 42 years old, and Xiaobing's age is 23 years old."

  Lin Feng said a lot in one breath, not caring whether Shen Leng understood or not, and just talked to himself. In the end, he even asked, "How about it, did you understand?"

  Lin Feng thought the other person wouldn't understand, and would definitely ask him to repeat himself. But instead, she nodded and said, "I understand, but how did you calculate those two results?"

  This result is beyond Lin Feng's expectations!

  Lin Feng couldn't believe it and stared blankly, asking, "Did you really understand just now?"

  Does he just say it once and the other side already understands?

  Shen Leng nodded slightly and said in a still calm tone, "Mm, I just don't know how you calculated the answer through those two formulas?"

  Lin Feng was speechless for a moment, he didn't expect the other party's understanding ability to be so strong. To think that when he first came into contact with quadratic equations, he spent half a day not understanding them, and only slowly understood them after going to ask his teacher for help.

  He only said it once and not very accurately, but the other party understood it. This strong understanding ability made him, a university undergraduate, feel deeply struck.

  "Alright, since you understand now, I'll explain this algorithm. Lin Feng let out a silent sigh in his heart, pursed his lips and continued to say, "To calculate the answer, it's actually not difficult, mainly it's about eliminating variables."

  "Eliminate?" Shen Lengxin muttered to herself, her eyes filled with confusion as she looked at Lin Feng, her body involuntarily leaning in closer.

  A faint fragrance came from beside Lin Feng, making him unable to help but turn his head to take a look. Who would have thought that the lips of Shen Qingxin, who was separated by a layer of gauze, had just touched his lightly. In this instant, Lin Feng was stunned.

  When he saw Shen Lengxin's eyebrows furrow, he was so scared that he hastily retreated two or three steps, took a few deep breaths, and just as he was about to speak, "I..."

  "Why are you standing so far away from me?" A soft and gentle voice interrupted what he was about to say.

  Lin Feng glanced at Shen Lengxin, only to find that she didn't have the anger and dissatisfaction he had imagined. Instead, her face was filled with confusion and perplexity, as if she had no idea what had just happened.

  Lin Feng finally let out a sigh of relief, secretly thinking that it was good the other person wasn't angry. However, although they were separated by a layer of gauze, the other person's lips had a hint of fragrance and elegance that made him unable to help but linger.

  Just thinking about this, Lin Feng secretly despised himself. Damn it, you hypocrite, your first woman is not even settled yet, and you're already thinking about other women. Are you still considered a person who has received higher education?

  Taking a few more deep breaths, Lin Feng pushed aside his complicated thoughts and looked at Shen Qingxin, saying in a somewhat hesitant tone, "Sorry, just now... I didn't mean to..."

  "Huh? What?"

  Shen Leng's eyes wandered back to Lin Feng, thinking about the places where they had come into contact. She couldn't help but lightly touch her lips with her hand, feeling a bit puzzled and curious in her heart. Why did she feel an unusual sensation when her mouth touched this person's mouth just now? It was a feeling she had never experienced before...

  But for some reason, as soon as the other party came into contact with him, he left so far away that she didn't even have time to feel it.

  Lin Feng saw that the other party did not pursue it, and did not want to get entangled in this aspect, so he quickly explained the term "消元" (xiāo yuán) in an attempt to shift the other party's attention. "What is meant by 消元 is to convert multiple unknowns into a single unknown. Oh, right, before that, let me mention that the word '元' (yuán) actually refers to an unknown number, and those expressions containing unknown numbers I mentioned earlier are called equations. The process of solving these equations is called solving equations..."

  As expected, Shen Lengxin's attention was completely drawn to this aspect after Lin Feng continued to explain the term "Mieyuan", and he listened intently to Lin Feng's explanation.

  The first update is posted, I hope you can give me some votes and support, of course, it's best to collect them and fatten them up before killing them!
