First recommendation: You can ask me about high school math.

Free shop is a good communication platform. Go and see more, and discover more advantages by yourself.

The second recommendation: Xiamen middle school students answer questions online

It is to imitate the model that Baidu knows. Not bad, but there is also the problem of integral. You can also solve the problem by thinking more. The process of integrating points is the process of deep understanding of knowledge.

The third suggestion:

People's Education Forum? High school mathematics forum

/forumdisplay.php？ fid=38。 page= 1

The forum of People's Education Publishing House is a good way of communication, and its popularity is not bad. Questions will be answered by moderators and regulars.

Not much recommendation, say the following:

1, I have been to every website, and I have chosen many websites. These three are the best I have found, and it is useless to write other useless ones.

I don't want to expect the teacher to answer questions online for free. Think about it from another angle. If there is such a website, it will not last long. How to maintain and retain people without income? So in fact, the network gives us more of a platform for communication.

3. If there is a problem, no one will go online again. In fact, it is better to discuss it with your classmates and teachers. I hope you can arrange your own online time! !

That's all, I hope my work can really help you! !
