Chief’s Tip Pet: Sweet Wife, New Online

Qi Anran writes very fast, and it took less than five minutes from the time she started writing on the blackboard to when she wrote the last number.

But at this time, there was almost no space on the blackboard. From this side of the blackboard, the whole blackboard was roughly divided into four sections, and the upper and lower parts were written on the other side of the blackboard.

Fortunately, her handwriting is delicate and beautiful, and every row and every column are as if they were measured with a ruler in advance, very neat.

Even if they don't understand the large number of problem-solving steps at all, they feel extremely comfortable and not bored.

After finishing all the steps, Qi Anran put the chalk back in place, then turned to look at the completely stupid math teacher, pointed to the last two answers, and said with a smile, "Teacher, is my answer correct? ?"

Song Baoqing woke up like a dream, and hurriedly lowered his head to look at the test paper with the correct answer in his hand, and started to stutter in amazement: "Yes, that's right, how is this possible?"

The students underneath looked at each other, their eyes dimmed because of the heavy studies and the teacher's insulting words, and they looked at Qi Anran in surprise and surprise.

Qi Anran looked at Song Baoqing with an extremely hard expression on his face. The corners of his lips were slightly hooked, and he said in a deep voice, "Since it is correct, please ask the teacher to use these problem-solving steps written on my blackboard to explain this topic."

Song Baoqing's already ugly face grew a little gloomy. He raised his head and glanced at the problem-solving steps on the blackboard, and then came down with cold sweat: "You...your steps are wrong."

"Wrong?" Qi Anran sneered slightly with her eyes, "Teacher, don't forget that you told me that the answer is right. A wrong step ended up with the correct result, can the teacher tell Where did I go wrong with these steps? Which step was wrong?"

"This..." Song Baoqing choked, glanced at the students who were staring at the podium, and said with a black face in anger and anger, "I have taught math for so many years, and I have never seen any math problem solved in this way! …This must be wrong! Have you searched for the answer to this question before? I don’t know where to find these crooked ways to solve the problem, just fill up the numbers, should I be fooled by you?"

Compared to him, Qi Anran was obviously calmer, with an ironic smile from the corner of his mouth, and said lightly: "The teacher hasn't read it, it doesn't mean it doesn't exist. German mathematician Georg Kantor once said After a sentence, "The essence of mathematics lies in its freedom." In many cases, the same math problem may have a lot of solutions. The same is the correct answer, and the teacher can't tell me where I am wrong. Can I be sure that these problem-solving steps are wrong? With just a word of yours, you have to decide whether a problem is right or wrong. Doesn't the teacher think that I am too overbearing?"

Qi Anran's writing on the blackboard is of course correct, but she is not using the well-prepared method of solving problems in high school, but the knowledge points of advanced mathematics.

The original intention was for this teacher to restrain him a little bit. Unexpectedly, he didn't even understand it. The level is obvious.

"you…"

"Just now the teacher took a bite of a little bastard, pig brain, we are inferior, we are not qualified to let you be a superior person to teach." Qi Anran interrupted Song Baoqing, pressing step by step, "but now the teacher But you can't even understand the problem solved by my inferior people, let alone explain it. I think the teacher, your teaching level is not enough, you don't have the ability and the qualification to teach us, what do you think?"
