**Reiny**, Saturday, February 26, 2011 at 2:40pmIt probably says simplify, not "solve"

If you post expressions involving mathematical symbols, it is best to switch the encoding to Western ISO-8859-1 which is available under "view/character encoding (on Firefox) or "view/Encoding" under Internet Explorer (Western European).

This way, you can take advantage of all the math symbols available.
