I'm not sure if this a valid question to ask on meta, but at what point (academically I guess) would one find themselves to start answering questions more frequently than asking them in Math.SE? I was browsing questions and answers of the site and the quality of the the answers provided, for relatively simple questions I could answer, is usually beyond that which I would find myself capable of providing currently.
There isn't a uniform level at which one is "ready" to answer questions. There are high school students posting great stuff, and graduate students posting not-so-great stuff. Not to mention the huge disparity in the level of questions.
If you don't see opportunities for you to answer questions, there are other ways to contribute:
- asking questions (obviously)
- voting on questions and answers
- editing (if you have 2000 points) or suggesting edits (otherwise)
- identifying duplicates and flagging them as such
And here is some further reading:
I think that everyone should try to answer questions, at least from time to time, once they have completed at least a portion of their first elementary algebra or geometry class.
If you look at the questions on the site, you will see that they indeed range from elementary school level up through graduate school level and occasionally beyond. Most likely you are capable of answering some of these questions, so you should give it a try.
If your answer is lousy, someone will probably come up with a better one.
