The homeroom teacher of the seventh class of Xinghai No. 1 High School, who is also the mathematics teacher of Lin Han's class, is just 55 years old this year and is in menopause.

As a mathematics teacher who has entered menopause for 5 years, Mr. Huang has never been so irritable, restless, and excited as he is now.

Especially, when he heard that the unscrupulous male student dared to let the vice principal ask the question on the spot, this Teacher Huang finally couldn't help but ridicule again.

"Principal Liu, ask the question, see what other tricks he has!" Teacher Huang seemed to have decided that Lin Han was a bad student, and shouted loudly and confidently: "A student like him, he doesn't shed tears when he doesn't see the coffin, and he asks questions!" ”

"Excuse me, Headmaster." Lin Han's expression was still plain, completely unaffected by the menopausal teacher, but let Principal Liu's right hand hold the chalk, a little hesitant.

Looking at Lin Han's calm and reassuring temperament, Principal Liu already had a good impression of Lin Han in his heart, and began to feel that Lin Han was really a mathematical genius who realized it later.

But now both sides are asking themselves to come up with the question, as the vice principal, they also need to press this matter down as calmly as possible, after thinking about it again, the principal Liu nodded slightly, clenched the chalk, and crossed the blank space vigorously.

In order to take care of Mr. Huang's face, the vice principal didn't dare to really hurt the hearts of his subordinates with a simple question, so he simply wrote down a pull question that he planned to use in the final test.

Unlike those teachers who like to fill up the number of questions from the online question bank, Principal Liu prefers to write his own questions, and is very proud of it, this question is the type and question he just came up with this week, and it is intended to be placed in the final semester to open up the gap between students.

Principal Liu once conservatively estimated that it is not easy for 1% of the thousands of students in the entire grade to get this question right.

However, for Lin Han, Principal Liu will not be too harsh, math problems, do not necessarily have to be solved to score, as long as the steps are correct, there can be corresponding step points.

Principal Liu himself had done this question and used five steps, and in his opinion, Lin Han was able to complete the first three steps, which was already good, indicating that he did have the strength to get a full score in this exam.

Although it is extremely difficult to get a perfect score, it is not uncommon for students to get it by luck.

Teacher Huang has been teaching mathematics for decades, and when she saw this problem, she couldn't help but look happy, she could see that this problem was quite difficult, and she thought that Lin Han's barely passing math score was very good.

She looked at Lin Han.

Just at the first glance, she was stunned, she saw that after the vice principal retreated, the hateful Lin Han actually just paused and began to write.

Listening to the familiar sound of chalk brushes on the blackboard, Principal Liu couldn't help nodding slightly, and subconsciously whispered: "Not bad, not bad." ”

This whisper fell on Teacher Huang's ears, but it was like thunder, shaking her bloodshot eyes, and she refused, let alone believed that the student who had bumped into her would really ...... Write out the right steps.

"Shhh

Lin Han ignored it and continued to write, writing quickly.

Soon, the first two steps clearly appeared in Principal Liu's eyes, making him nod slightly, Lin Han was able to find the solution so quickly, and the next few steps could almost be launched, it seems that ...... He's got the real thing.

I just don't know, can he figure out the solution to this problem? In Principal Liu's heart, he began to look forward to Lin Han's performance, if Lin Han solved this problem, there is no doubt that in mathematics, this student is enough to rank among the top students.

The third step was written out by Lin Han.

Principal Liu narrowed his eyes and stretched them slightly, he found that this was a different step from his own answer, but it could indeed be used to solve these knowledge points.

Teacher Huang was always paying attention to Principal Liu's every movement at this time, and when she saw Principal Liu's eyes narrowed, she couldn't help but feel happy in her heart. Yes, it must be a wrong answer.

I have just thought of the second step of this question, where can the other party think of more so quickly?

It must be wrong.

Teacher Huang approached Principal Liu's ear and was about to ask a question, but was gently pushed away by Principal Liu, who was in high spirits.

When Principal Liu saw the fourth step written by Lin Han, he nodded excitedly and said: "Yes, yes, I actually used these basic knowledge points to solve this question, which I really didn't expect at the time. ”

"Huh?" Teacher Huang stayed on the spot, blushing and shouting, "How can this be, he, solved it?" ”

Hearing Teacher Huang's voice, Principal Liu suddenly remembered the current environment, couldn't help but blush, coughed, and nodded: "Yes, it's solved." ”

"It just so happens that he's seen it." Teacher Huang began to speak a little incoherently.

Principal Liu originally wanted to be angry, but after a little thought, he quite understood Teacher Huang's embarrassment, in this way, there were simply no steps to go down, standing in the teacher's position, he was about to open his mouth to ease the atmosphere and give both sides a step, who knows, Lin Han suddenly held the chalk and wrote a math problem on the other half of the blackboard.

"Shhh...... This is! ”

"Calculus?" Teacher Huang couldn't help but widen his eyes and looked at the question that Lin Han gave him.

"This ...... This Lin Han is a self-taught mathematical genius. Principal Liu looked at Lin Han, who was struggling to write, and secretly said to himself that he was surprised.

Calculus is the mathematical content in the university, looking at the difficulty of Lin Han's problem, I am afraid that half of the college students in first-class universities can't solve it, after all, this homework is originally easy to learn and difficult to understand, plus complex and terrible calculations, conversion, President Liu looked at it, and even he felt that Lin Han's problem seemed too difficult......

Lin Han was writing the title, but he kept in touch with Li Junjie.

Just being questioned by the mathematics teacher, while the vice principal was also present, Lin Han made up his mind to take this opportunity to show his self-learning ability, and then make the vice principal agree to his self-study.

Therefore, Lin Han whispered to Li Junjie and found a test question on the Internet that only the university mathematics department would practice, so as to prove his strength to the teachers around him.
