Chapter 1856: Simple, dislocation and subtraction

Among the four subjects, for most people, mathematics is the most time-consuming subject. After all, it needs to be calculated back and forth on draft paper. The amount of writing is more than that of Chinese composition. Some candidates even two draft papers are not enough. , You can imagine how hard it is.
No wonder some people say that after a math exam, brain cells will die.
Li Yun strolled out of the teaching building. Many candidates saw his confident and handsome figure walking out of the school gate from the window. They were also shocked, and they couldn't help cursing "I'm Cao"!
Out of the school gate, Li Yun saw a group of people in silence.
"What?"
When the reporters saw Li Yun coming out, they were all shocked. They were still sitting in the car blowing on the air conditioner. Why did they run out?
As for the parents who were waiting for the students to come out, they were all speechless after seeing that Brother Li, the of learning, handed in their papers and walked out within an hour.
Compare their children, the gap is too big! ! !
"Student Li Yun," a parent gave a stiff smile, "is this year's math problem simple?"
Many parents of children with poor maths also look forward to it.
"I think it's okay, quite simple."
With Li Yun's "honest" answer, a group of parents breathed a sigh of relief.
"Isn't the last math problem the hardest? Li Yun, did you do it?" Another parent asked in confusion. His son's math is good, so he wants to rely on math to keep the distance. The topics are simple and meaningless.
"Yes, yes! Let's talk about it, classmate Li Yun!"
The reporters also arrived carrying cameras and microphones, insisting on Li Yun to explain the solution to the last math problem.
"It's very simple." Li Yun replied with a confident smile: "I know that formula at first glance. Take the logarithm first, then reverse the numerator and denominator. After splitting the terms, subtract the first N terms. And Sn."
If it’s love, it’s as simple as that. jpg
After a little play, Li Yun hurriedly flashed people, leaving behind a dumb-faced reporter and dumb-faced parents-they had forgotten high school mathematics a long time ago, and they didn't know what it was.
However, when Li Xueshen simply said the solution to the last question, the parents were still a little relaxed. The reporters even started posting Weibo to promote Li Yun’s very simple remarks on the last question, which attracted a group of people to wait. Netizens watching the melon for college entrance examination.
"This year's math is simple? It's great. Three years ago, the math for the college entrance examination made me hard to cry. I still remember it!"
"Senior sister, I am envious of my real name."
"666, won't there be many people with perfect scores in math this year?"
At five o'clock in the afternoon, the candidates handed in their papers and left the examination room.
At the end of the exam on the first day, the parents waiting at the school gate wanted to greet their children happily, but as the students walked out with heavy steps, they found something wrong.
Why these students wrinkled a bitter face one by one, thinking hard, as if they were still immersed in the exam!
Isn't it simple?
"Student, how did you do on the test?" An impatient parent couldn't wait to hold a classmate and asked, "I heard that this year's math is very simple?"
"simple?"
The dull-eyed classmate repeated these two words once.
"Yes, a classmate came out earlier and said that the last math problem is very simple this time."
"Simple... The last question is very simple..."
With a wow, the classmate cried and ran away in tears.
Leave a group of parents at a loss.
