Math, when I was in primary school, I thought you were my best friend. You won the glorious title of literacy for me, and you showed me the sacred palace of mathematics, a wonderful science. I think you are sincere and never afraid of authority.

However, with our growth and lower grades, mathematics plays an increasingly important role in the discipline. It's like two friends we haven't seen for a long time, and it's like we've seen you there all the time, and we've been silent. Besides, you should not be so naive as children nowadays. Addition, subtraction, multiplication and division are all your problem-solving routines. Now, you seem to have grown up. I don't know who taught you badly and made you afraid, even afraid. You don't belong to our friends anymore.

Math, I want to treat you well, and I really want you to be the same.
