"Then you teach me how to use these symbols to answer the questions I came up with. The woman said flatly, this kind of commanding tone seemed to make Lin Feng teach her without doubt.

When Lin Feng heard this, he couldn't help but smile bitterly, "Can't you use a gentle tone?

"Gentle tone?" The woman frowned again, looked at Lin Feng with some confusion, shook her head, and said bluntly, "What kind of tone is that?"

Hearing her say this, Lin Feng couldn't help but hide his face and was speechless, you are a cheat, you don't even know this, I really don't know if you still have feelings. In this regard, Lin Feng could only say helplessly, "Then you should always tell me your name! I still don't know your name? You shouldn't let me teach someone I don't even know the name, right?"

The scene was silent for a while.

"Shen Lengxin. A cold voice came from Lin Feng's ears......

Sure enough, it's cold enough!

"Well, okay, I'll just call you Leng Xin. The symbols that I use today to answer the question, which I call unknowns, are used as metaphors for things that are not yet known. Then answer the question according to the meaning of your question. Lin Feng took the piece of paper in Shen Lengxin's hand and pointed to the symbols and said.

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

"For example, in your first question, Xiaohai said to Xiaobing: 'When my age is your current age, you are only 4 years old. The soldier said to the sea: 'When my age is your current age, you will be 61 years old.' 'Let me ask, how old are Xiaohai and Xiaobing now?'

"I first assume that the age of Xiaohai and Xiaobing is already known, assuming that Xiaohai's age is x years old, and Xiaobing's age is y years old, we know that the age difference between the two will not change with time, so X minus y is the age difference between the two of them, which is represented by X-Y, and I use the - symbol to represent Minus. ”

"Xiaohai said to Xiaobing: 'When my age is your current age, you are only 4 years old. In this question, we can know that the age of the soldier minus the age difference between the two of them is equal to 4, so that we can get a formula, y-(x-y)=4, I use the = symbol to represent the equal. ”

"Then, from the soldier, he said to Xiaohai: 'When my age is your current age, you will be 61 years old. In this question, according to the representation just now, we can get another formula, x+(x-y)=61, combining these two formulas, I calculate x=41, y=23, so Xiaohai's age is 42 years old, and Xiaobing's age is 23 years old. ”

Lin Feng said a lot of words in one breath, and he didn't care if Shen Lengxin understood it or not, he just said to himself, and finally asked, "How is it, do you understand?"

Originally, Lin Feng thought that the other party would not understand and would definitely ask him to say it again, but she nodded and said, "Understood, but how did you calculate those two results?"

This result was beyond Lin Feng's expectations!

Lin Feng was a little incredulous, stunned, and asked, "Did you really understand just now?"

You know, he just said it once, and the other party understands it?

Shen Lengxin nodded lightly, and said lightly, "Well, I just don't know how you calculated the answer through those two formulas?"

Lin Feng was speechless for a while, he didn't expect the other party's comprehension ability to be so strong, you must know that when he first came into contact with binary equations, he didn't understand it for a long time, and finally went to consult the teacher before he slowly understood it.

Now that he only said it once, and it was not very accurate, the other party understood that this strong understanding ability had to make him, an earthling with a bachelor's degree, a double blow.

"Well, now that you understand, I'm going to explain the algorithm. Lin Feng sighed speechlessly in his heart, pursed his lips, and continued, "It's actually not difficult to figure out this answer, it's mainly to eliminate the yuan." ”

"Xiao Yuan?" Shen Lengxin muttered this unfamiliar word in his mouth, looked at Lin Feng with a puzzled expression, and couldn't help but get closer.

A faint fragrance came from Lin Feng's side, and he couldn't help but look back, who knew if he would die or not, just that lip was imprinted with Shen Lengxin's light lips through a veil, and at this moment, Lin Feng was stunned......

When he saw Shen Lengxin's brows furrowed, he was so frightened that he hurriedly took two or three steps back, took a few deep breaths, and just wanted to speak, "I ......"

"Why are you so far away from me?" a quiet voice interrupted what he was about to say.

Lin Feng glanced at Shen Lengxin and found that she didn't have any imaginary anger and dissatisfaction, but only a puzzled and dazed expression, as if she didn't know what had just happened.

Lin Feng breathed a sigh of relief at this time, and sighed secretly in his heart, fortunately, the other party was not angry. However, although there was a veil, the faint fragrance and clear talk of the other party's lips made him can't help but linger.

Thinking of this, Lin Feng secretly despised himself, damn, you hypocrite, your first woman hasn't been dealt with yet, so he thinks about other women, are you still a highly educated person?

Continuing to take a few deep breaths, putting aside his complicated thoughts, Lin Feng looked at Shen Lengxin and said in a somewhat slurred tone, "I'm sorry, just that...I didn't mean to..."

"Huh, what?"

Shen Lengxin looked back at Lin Feng blankly, thinking about the place where she came into contact with Lin Feng, she couldn't help but touch it lightly with her hand, with some doubts and curiosity in her heart, why when her mouth just came into contact with the mouth of the person in front of her, she couldn't help but have a strange feeling in her heart, which was a feeling she had never felt before......

It's just that, for some reason, the other party just made contact with him, and he left so far away, so she didn't have time to experience it.

Lin Feng saw that the other party did not pursue it, and he didn't want to be entangled in this regard, so he hurriedly explained the word "elimination of yuan", trying to use it to divert the attention of the other party, "The so-called elimination of yuan is to turn multiple unknowns into one unknown. Oh, by the way, before I say that this element actually refers to unknowns, and the previous formulas that contain unknowns are called equations, and the process of solving equations is called solving equations......"

Sure enough, after Shen Lengxin heard Lin Feng continue to explain the word "elimination yuan", his mind was completely pulled by Lin Feng in this aspect, and he listened attentively to Lin Feng's explanation.
