2. "Success = your teaching+our efforts", you gave us the formula, and we will show you the other half. Wish you a happy Spring Festival!

3. We are like scalars, with only size and no direction. You have let us find the direction, let us become vectors, and let us find our dreams. I wish you health and peace in the new year and all the best!

4. 1 year is about to begin. I wish the teacher good luck and success. I feel that the seasons are like spring, and my life is colorful and colorful. Occasionally, I will make a fortune at 8 o'clock, and all my troubles will be forgotten. Please accept our best wishes from 10.

5, inch by inch of chalk, dyed your hair white, addition, subtraction, multiplication and division is not enough for your care, I sincerely wish you happiness!

6. The trajectory I respect will always be centered on you and will always be an increasing function. This is an absolute value. Although I want to continue my studies, I will leave a parabola to represent my blessing to you. I wish you a happy New Year!
