a new teacher

Teacher Chen:

Hello!

In the past six months, you have given us an N class, and in these classes, I got 2N knowledge, maybe other students got more than I got, 2. 5N, 3N, maybe even more. Because the pay is directly proportional to the harvest, the more you pay, the more you gain. When I paid 90% of the effort, I gained 90 points, and other students gave me 100 points more than I paid. This is math.

You stand in an irregular three-dimensional classroom, and in front of the rectangular blackboard, many figures are drawn with cylinder-like chalk.

We are sitting in the front view:, left view:, top view: on the chair, squatting on the rectangular table, listening to the geometry of a point and a line. Under one lesson, go to the blackboard and look at the chalk. It is now a cone, you can imagine, the teacher is your hard work. On the workbook, the forks and hooks in the test paper will satisfy you! In the past six months, you ran from the first floor to the fifth floor every day, and then from the fifth floor to the first floor. You always see that you are out of breath, and you run red and face. Because of your concern, everyone will also give you condolences, but you said : "Exercise." You work hard for us, we look in the eyes, remember in my heart. If we don't understand things, we will always make you angry and sad. Now think about it!

To be honest, I am a "mathematical low energy child". When it comes to mathematics, my heart is inexplicably nervous and scared. Especially the equations and geometry in mathematics, what 3x, –2y+8z, m∥n, a⊥b... I fainted at first sight. But you, with your own exquisite and beautiful mathematical language, took me into the wonderful mathematics hall, let me know that "mathematics" is not terrible, "mathematics" is an art; you let me in the ocean of mathematics I am enjoying the fun of playing in the math playground, let me appreciate the infinite charm of mathematics. I really appreciate you very much. I will do my best, and I am not satisfied. Teacher Chen, I am proud to be your student, but I hope that you can become a good teacher in my study, a good friend in life, OK?

I wish you

Work well, all the best

your student***
