# Math Help - Negative indices

1. ## Negative indices

Hi, I'm having problems trying to write a negative index. Whenever I do e.g y^2 it's fine, but y^-2 and the 2 goes back to a normal size number.

2. $$y^{-2}$$ gives $y^{-2}$

Of course you can put any number of symbols in there: $y^{-\frac{x^2}{2}}$

3. 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 { }

4. Thanks guys.
