I'm a Ph.D. student, working on limit theorems of probability theory.
When I edit a post, I suggest the owner to check whether I didn't change the meaning.
The less detailed is the OP (attempts, etc...), the less my answer will be.
My activity on math.stackexchange consists in:
- trying to answer questions which didn't receive answers;
- upvote/downvote questions/answers;
- edits, retags of questions;
- review tasks;
- flag obsolete comments, answers which should be comments.
