new to mathematica, looked at the help, but did not get the help i needed..

I want to write a function that does multiple calculations in its body, then 
it returns a value.
I am talking about functions similar to functions that you can declare in 
C++.
can anyone give me an example?


in C++, a function would be like, (note int means integer)

int zzz(int s, int y)
{
   int  Q;
   Q = s*y;
   return Q;
}


well thats just a simple example, the body of my function is going to be 
complicated...
I know in mathematica, I can solve the same zzz by
zzz[s_,y_] := s*y;

However, what if i want the body more complicated and do more than one 
thing??
