In one case I went to write "about [dollar sign]20 to [dollar sign]25 an hour" and got weird text in my answer (as you can see below). Apparently having two dollar signs creates some kind of special formatting. This is what it looks like:

about $20 to $25 an hour

That happens because mathJax is enabled on this site, It uses the dollar sign by default.

To avoid getting bitten by this you can escape the \$ using \$:

\$20 to \$25
