Using braces to label parts of an equation

How do I put horizontal curly braces beneath and over parts of a formula? I tried to use \stackrel and \mathtop, but it did not work.

    I have found. I should use \overbrace{}^{} and \underbrace{}^{}.

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} +
   }^\text{complex number}

Their result: example showing the result of \underbrace{•} and \overbrace{•}
