Using braces to label parts of an equation

I have formula and I need to make horizontal curly brace underlying part of it. Also I need curly braces on top of the formula. How to do it? I tried to use \stackrel and \mathtop but it does not work.

I have found. I should use \overbrace{}^{} and \underbrace{}^{}. –  msh Feb 29 '12 at 17:52

You can try the following commands:

\overbrace{your-formula}^\text{your comment} 
\underbrace{your-formula}_\text{your comment} 

An example that I took from Wikibooks:

\[
  z = \overbrace{
    \underbrace{x}_\text{real} +
    \underbrace{iy}_\text{imaginary}
   }^\text{complex number}
 \]

Their result: enter image description here
