[tex]y^{-2}[/tex] gives $\displaystyle y^{-2}$

Of course you can put any number of symbols in there: $\displaystyle y^{-\frac{x^2}{2}}$ - Mar 19th 2011, 12:43 PMTheChaz
For subscripts, exponents, and the like that have

**more than one character**(as in "-2", which is two characters), you need to employ the method that "-1" suggested above: put them in { } - Mar 20th 2011, 09:57 AMTurlock
