Daniel is very dissatisfied with his new job, he is also a Harvard graduate, but he has had to work for eight years as an "inferior" because his father lost all his money in the stock market crash nearly eight years ago, and he hopes to return to the university laboratory one day to continue his mathematical research. But the reality is that he now has to stand in the very poorly furnished classrooms of a public high school, facing students from the slums.

It was already the best job Daniel could find, and the New York State Welfare Department told him that if he didn't come here to teach, he would have to work as a construction worker in the Public Works Department, and because he had no construction training, he would only be able to become a lowliest porter.

Damn the economic crisis, it's been so many years, and the result is still ghostly.

Daniel cursed the economic crisis, but that didn't make him feel better. He stared at the teenage half-boys in the room, and he felt that he could see the future of these people: the mafia thugs, the street girls, the dock workers—and so on. No one is likely to use what they have learned here in the future.

The more Daniel thought about it, the more angry he became, these people didn't understand the value of knowledge at all, and they shouldn't have taught them these precious crystals of human wisdom at all, what was the difference between this and tyrannical things?

With a lot of resentment, Daniel turned around and wrote on the blackboard what he was going to tell for the day.

At this time, he heard someone in the classroom say, "Teacher, I think you made a mistake in writing the equation, and a negative sign was missing on the third line." ”

"Oh yes?" Daniel was about to be angry, but he still habitually looked down at his textbook, only to realize that there was indeed a negative sign missing, "Yes, clever, I have read the textbook beforehand." ”

Daniel endured his annoyance and complimented him, he hadn't looked back at the student until now, anyway, he was just a guy who had flipped through his textbook in advance and wanted to pretend to be smart......

But the voice continued: "My parents only scraped together enough money to enroll me in school yesterday, and I don't have textbooks. ”

Daniel finally turned around and found that it was the girl sitting in the corner who was talking, dressed in very modest clothes, and unlike the other girls in the class who tried to dress up in fancy clothes, she had no makeup at all and was facing the sky.

She continued: "If there is no minus, the whole equation doesn't hold, so I think you must have missed it. ”

"Oh yes, you're smart! Then you can come up and solve this problem! ”

Daniel casually chalked up the question he had just copied on the blackboard.

The girl nodded, then stood up and walked through the classroom with a fluttering stride, to the blackboard and picked up the pen, and in a few moments she had completed all the steps to solve the problem.

Daniel glared at the girl, and said to himself that she must have read the textbook beforehand.

Suddenly, Daniel understands that this must be a trap set by these bastards for his new teacher, deliberately making the bullied female students with good grades in the class pretend to be freshmen, in order to give him a disadvantage.

Daniel wasn't going to let them get his way, he was a Harvard graduate, and he had in his head a problem that a public high school student couldn't solve.

It's time to show these slum boys what they're capable of, to let them know that they're fundamentally different from them, and to let them know what the difference is.

So Daniel closed the textbook, wrote an equation on the blackboard, and made a gesture of please to the female student. To solve this problem, you must apply the relevant knowledge of integrals, and if you are only a middle school student, you should not even understand many symbols in equations.

As a result, the female students completed the solution quickly, and took fewer steps than Daniel used back then.

Daniel looked at the simplified steps of the female student in amazement, completely speechless.

"You...... Studied calculus? No, you studied math in college? ”

"I worked in a used bookstore, and a customer sold a lot of used math books. The bookstore owner refused to pay a high price, so I bought the used books with my own wages. ”

"You talk nonsense! How can it be ...... just looking at old books"

"Teacher, don't you know that there is a man named Thomas Edison!" One of the students below started laughing, which immediately caused a burst of laughter.

Daniel became more and more convinced that it was the students who were playing him, and he became angry and yelled at the students, "Thomas? Edison was theoretically a dwarf! He just happened to be in time for the good times when he could make great inventions with rough real yàn! ”

After yelling, Daniel stared at the girl in front of him, and he suddenly had an idea.

He wrote down Fermat's conjecture on the blackboard and said to the girl, "Come on, prove it." ”

Daniel was convinced that the girl could not prove this conjecture, because since the Frenchman Pierre? Morality? After Fermat proposed this conjecture, countless mathematicians tried to prove it or falsify it for two hundred years, but failed.

This is not something that only a sixteen or seventeen-year-old girl can attest.

But the girl thought only for a while, and then began to write the blackboard.

Daniel was disdainful at first, but gradually, the contemptuous smile on his face disappeared, and he closed his mouth tightly. After another ten minutes, Daniel's mouth grew and shock was written all over his face.

In this way, the time of the class passed, and the girl clicked the period in the corner of the blackboard, and the whole blackboard was densely filled with equations.

Daniel suddenly remembered what Fermat had said: "I am sure that I have found an excellent way to prove it, but there are too few gaps in the book to write it down." ”

The girl looked back at Daniel and whispered, "I'm done." ”

"This ...... I ...... "Daniel's mathematical literacy sued him, which proved to be true, but he was not sure."

At this time, there was a heckling whistle in the class.

Daniel turned around and shouted, "Quiet! Do you know what a great time it is? The Fermat conjecture has just been proven! Damn it! Do you know how many geniuses who are a hundred times smarter than you have been stumped by this conjecture over the past two hundred years? Damn it! Give me quiet! ”

Daniel turned his head and looked at the girl with an inexplicable face, and finally managed to stabilize his feelings, and said to the girl, "What's your name?" ”

"Mary? Belle. ”

Daniel swallowed, and he suddenly realized that the time had come for him to return to Harvard's research room.

"Listen, don't tell anyone else that you've proven this conjecture, okay?"

"Not good." Mary? Belle said to Daniel dryly, "I already know that I have done something that countless geniuses have not been able to do for two hundred years, and this is a great thing. I can make a splash in the world. ”

"Listen," Daniel swallowed again, "mathematics is not that remarkable, your achievements are recognized in a small circle at best, and the big capitalists don't care about that at all, because all they need about mathematics is to help them make books, you know?" ”

"He wants to monopolize your achievements!" Suddenly, someone in the class shouted, "We all saw it, it was Belle who did the calculations!" ”

"Shut up!" Daniel shouted, "Shut up, y'all!" ”

But instead of shutting up, the students became even more noisy, so Daniel slapped the table hard: "You guys think so well! Who will believe you! Ha? Who would? You're just a bunch of slum kids, living in dirty government housing, or shabby cheap apartments! None of your families are highly educated! Who will believe your words? ”

The classroom finally fell silent.

Daniel laughed a few times in satisfaction, then said, "That's right, that's it, I'm the only one in the room with a higher education, I'm from Harvard!" Only I can solve the conjecture! And you're stupid kids who want to steal my work! Hahaha! ”

At that moment, the girl named Marie Belle turned her head to look at the window next to the classroom, as if she was searching for something. And Daniel was still looking forward to his future life triumphantly, not paying any attention to the strangeness of the girl.

Immediately after, the girl turned her head to look at the side with the door, and her gaze carefully swept over the window.

Finally, her gaze returned to Daniel.

She stepped forward and nudged Daniel.

Daniel fell backwards, staring wide-eyed at the girl's face.

Then the back of his head hit the protruding corner of the lectern.

The moment Daniel fell to the ground, a girl in the classroom let out a slight exclamation.

Mary? Belle immediately found the girl, stared at her and said, "Shut up, you idiot. ”

And then Mary? As the class watched, Belle smeared some chalk ash under Daniel's boots, and when she was done, she put the chalk with her fingerprints back into the pile of chalk in the chalk box.

"Mr. Daniel stepped on the chalk and fell, which was an unfortunate accident." She said to the students in the classroom with a nonchalant face, "All of us are the only witnesses, I have looked out the window, and no one will just see the scene just now." So as long as we say that, no one will bother us. Of course, you can choose to denounce me, but it will only give you a small penny, and then you will still be children from the slums, living in squalid public housing and low-rent housing, and people will not even believe that you can solve the equation. And if you keep it a secret for me, I promise that in the future I will take you out of your present fate. ”

The students in the classroom looked at each other, not used to making such decisions - they were just ordinary teenagers, and although many thought they would be part of the mafia and had blood on their hands, the sudden murder still shocked them.

Finally, just mentioned Thomas? Edison's prickly head said, "Okay,! This is the end this bastard deserves, and I support you! ”

Immediately afterward, the classroom resounded with different levels of harmony.

In this way, there was another unremarkable accident in a public school in the suburbs of New York State, and one of the witnesses to the accident was an inconspicuous girl from the neighboring state of Pennsylvania, and no one knew that this was the beginning of the girl's story.
