This afternoon, I had nothing to do at home, so I picked up a math extracurricular reading and read it. I saw a topic like this:

Xiaohong wrote a seven-digit number, three eights and four zeros. When Xiaohong read this number, her grandmother only heard Xiaohong read two zeros. Ask Xiaohong what this number might be.

I thought hard, thought over and over again, and finally came up with four different answers in order. The four different answers are: 8080800, 8080080, 8080008, 8000808.

From this topic, I understand that no matter what topic you do, you can't just be satisfied with coming up with an answer. Only by considering problems comprehensively and orderly and developing good thinking habits can we really learn mathematics well.
