Chapter 11

Qi Enron's writing speed is quite fast. It takes less than five minutes from the time she starts writing on the blackboard to the time when she writes down the last number.

But at this time, there is almost no space on the blackboard. From this side of the blackboard, the whole blackboard is roughly divided into four sections, up and down to the other side of the blackboard.

Fortunately, her handwriting is beautiful, and every row and column seems to have been measured with a ruler in advance, which is very neat.

Even if they can't understand the whole process, they feel very comfortable and not bored.

Qi Enron finished all the steps, put the chalk back to its original position, then turned to the completely stupid math teacher, pointed to the last two answers and said with a smile: "teacher, is my answer right?"

Song Baoqing wakes up like a dream. He looks down at the test paper with the correct answers in his hand. He is so surprised that he stutters: "yes, yes, how can it be?"

The students at the bottom looked at each other, their eyes darkened by the heavy study and the insulting words of the teacher suddenly lit up, and looked at Qi Enron in surprise and surprise.

Qi Enron looked at Song baoqingnan, saw the extreme face, slightly hooked the corner of his lips, and said in a deep voice: "since it's right, please use the steps I wrote on the blackboard to explain the problem."

Song Baoqing's ugly face became more and more gloomy. He looked up at the steps on the blackboard, and then came down: "you... You are wrong in these steps."

"Wrong?" Qi Enron said with a sneer, "teacher, don't forget that you just told me that the answer is right. A wrong step leads to a correct result. Can the teacher tell me what is wrong with these steps? Which step is wrong? "

"This..." Song Baoqing choked, glanced at the students under the platform, and said with a black face, "I've taught mathematics for so many years, but I haven't seen any mathematical problem solved like this! This... This must be wrong! Have you searched the answer to this question before? I don't know where to find these devious ways to solve problems. I just make up for the number. Do you really think I'll be fooled by you? "

Compared with him, Qi Enron was obviously much calmer, with an ironic smile on his lips, and said lightly: "the teacher hasn't seen it, doesn't mean it doesn't exist. German mathematician Georg Cantor once said, "the essence of mathematics lies in its freedom.". In many cases, the same mathematical problem, it may have a lot of solutions. The same is the correct answer, the teacher can not say where I was wrong, how can I be sure that these steps are wrong? Just by your words, you have to decide whether a question is right or wrong. Don't you think you are too overbearing? "

Qi Enron wrote on the blackboard that these were right, but she didn't use the high school method of solving problems, but the knowledge of advanced mathematics.

The original intention is to accept the teacher, let him more or less convergence, unexpectedly he did not understand, the level can be seen.

"You..."

"Just now, the teacher was a little jerk, a pig brain, a pair of us are inferior, not qualified to let you this superior to teach." Qi Enron interrupts song Baoqing's words and says step by step, "but now, teacher, you can't even understand the problem solved by me, let alone explain it. I think your teaching level is not enough. You don't have the ability and qualification to teach us. What do you think?"
