Chapter 127: Three algorithms

Chapter 127 Three Algorithms
Su Mian's total grades are counted down in the class, and her physical and chemical grades are not bad. The worst thing is mathematics. She has passed the test with 9 points.
Everyone stared at Su Mian, some were hot, some were simply looking for fun, and some were helplessly shaking their heads.
"Then classmate Su Mian, please answer!" The algebra teacher was silent for a while and finally said, his eyes were a little dazed and out of focus, he didn't know Su Mian.
The high school of this era allows teachers to remember names, and unless you study well, nothing else will be discussed.
Su Mian's grades were so bad that the algebra teacher didn't even notice that there was such a person in the class.
In full view, Su Mian stood up, before speaking, the classmates below burst into laughter again.
If Su Mian can answer, unless the sun comes out to the west.
Ignoring the ridiculous laughter, in his previous life, Su Mian would cry aggrievedly when encountering this situation.
In this life, she will no longer let herself shed tears easily, and will no longer give people a chance to laugh.
Su Mian didn't say the answer immediately, but calmly walked onto the stage from the last breath. Under the surprised gaze of the algebra teacher, he took out the chalk and began to check the calculation in the black and white blank.
Each step is clearly written, with a total of three lines, and even the mathematical formulas used are listed aside. After finishing this, Su Mian listed two other algorithms, and finally gave the number 1.
The three methods add up to less than five minutes!
This question is not very difficult. The key is to solve it cleverly. If you follow the habit of thinking, you can’t solve it within ten minutes!
In the audience, more than 60 classmates including Sun Ying were stunned, each with their mouths open enough to swallow an egg. Su Mian used to be able to test 9 points is fake! Do you just want to test 9 points!
In particular, Sun Ying's eyes were almost smashed on the table, Zhang Yanjie said that Su Mian was poor in mathematics, and any question she asked could embarrass her!
This is so embarrassing for her, it clearly made her show the limelight?
On the stage, the algebra teacher looked dazed, and his easygoing smile was a little distorted. In just a few minutes, this classmate actually thought of three different algorithms. Obviously this was to understand the intention of the questioner, and she finally chose the simplest one!
Her name is Su Mian? Why hadn't he noticed that Su Mian in the class was so quick thinking!
Li Yajun was the most shocked. He knew how Su Mian's math was. He knew better than anyone else. Starting from the winter vacation study group, he found that Su Mian was improving. The questions he asked these days were even tougher, even he couldn't handle it.
But he obviously didn't expect her to make progress so quickly, it has only been two months since the winter vacation!
"Yes, let's learn about Su Mian's problem-solving ideas!" The algebra teacher nodded, still keeping his right hand behind his back, looking at Su Mian more amiably.
Sun Ying rolled her eyes in her seat, "Maybe the blind cat hit the dead mouse!" Sun Ying said in a very loud voice, and she never cared about which teacher, her father was the principal, who was she afraid of?
The algebra teacher's expression sank, but he didn't say anything.
The students below have quit!
"Sun Ying, what you said is a bit too much! You just asked Su Mian to get up and answer the question, didn't you just want to make a fool of yourself? Now that someone has answered it, and answered three algorithms, why are you not convinced? "
"That is, if you are not convinced, you should do a question too!"
Sun Ying stopped talking immediately. Mathematics was also her weakness. She had never passed the exam.
