I don't think we can do it on this forum. We generally use text (sometimes with special characters like α≠√∞) or post pictures.

x, x^3 x^x, sqrt(5), etc. We use calculator notation a lot.

One could also use TeX notation. e.g.: 5 \over 3 for 5 _ 3 Advantages: less ambiguous than some other notations, some people have TeX viewers, relatively easy to earn basics well enough to read without viewer, open (public) format, virtually any math notation can be represented well Disadvantages: some people do not have TeX viewers, some will find it hard to read,

Yes, I like TeX, but it's a little much to expect people to copy/paste to a reader, methinks.

I'm not good at making graphics files from programs, but I did make a few (like my avatar). :P
