Finally, the math teacher's eyes fell, his lips moved, and he said, "Sixteen! ”

The classmates secretly breathed a sigh of relief, fortunately they didn't call themselves, it was really a crisis.

Mathematics is Gu Nianxi's worst subject, and it takes her a long time to solve the answer to each problem, and it may not be right.

Nervous! Particularly nervous.

Gu Nianxi slowly swallowed and stood up, his palms were full of sweat, and his palms would usually sweat, let alone when he was nervous.

The math teacher continued, "Gu, then you can solve it. ”

"Yes...... Yes" She stuttered a little when she was nervous, seeing her like this, the math teacher frowned unhappily, Gu Nianxi panicked, and immediately said very fluently: "If you have an+1/an=n/n+1, then an/an-1=n-1/n...... a2/a1=1/2, so an+1/a1=1/n+1, then an+1=a1/n+1, an=1/n. ”

After speaking, Gu Nianxi secretly took a deep breath and stared at the teacher on the stage with her eyes, but the math teacher's expression made her a little depressed.

Did she get it right? Why is the teacher's face a little strange...... Is it a mistake?

The math teacher slowly came back to his senses, and said with a smile of relief: "The solution is good, the answer is correct, Nian Xi, this time it is very progressive, not bad, I hope to make persistent efforts." ”

Gu Nianxi smiled and nodded, and was about to sit down, only to hear the math teacher say in a serious tone: "And!" Gu Nianxi, do you know how much you influence the image of students?! ”

Gu Nianxi was stunned when she heard this, her little face wrinkled slightly, and she looked at the teacher with puzzled eyes.

What's wrong with her, affecting the image of students? Isn't it right, it's because I usually answer it incorrectly......

Faced with the confusion on her face, the math teacher wrinkled her eyebrows helplessly and continued: "Don't be stunned, I said your hair." ”

The students laughed out loud, and the math teacher looked serious and swept his eyes coldly, as if to warn, and the students consciously shut up when they saw this.

"That...... Teacher, my hair is natural, not ......" She just wanted to explain that hair is not dyed, it is natural.

The math teacher didn't wait for her to finish, and immediately interrupted and said, "Not by nature!" Hopefully I'll see a normal black next week, sit down! ”

Being said by the teacher, Gu Nianxi suddenly felt very innocent, she secretly bit her lip and sat down.

The teacher said this as if she was not a good girl. Well, it's her fault that her hair grows like this!

In fact, it was not one or two teachers who asked Gu Nianxi to dye black. Although Gu Nianxi is a mixed-race child, not exactly like a foreigner, but she has a dark green soft hair, and the school rules do not allow her to dye her hair color, although she is natural, but the teacher feels afraid that it will affect other students, and the school rules or something.

Gu Nianxi also dyed her normal black hair for fear of affecting the school rules or something, but after a long time, her hair slowly grew. Cut and cut, and the dark green hair was seen again.

Gu Nianxi had no choice but to dye it again, the growth of her hair is like the season, and the spring breeze blows and grows!

changed back to dark green, what can she do, besides, dyeing hair costs money, and Gu Nianxi can't have money to dye it every time.

During the end of class, Gu Nianxi was carrying a small face, her eyes were blank, and she was lying on her side on the table.

Oops~ Why is her hair color dark green, and she is so depressed that she is different from others......

At this time, there was a commotion outside, and the noise was faintly heard.
