Mathematica  has a powerful array of functions that solve equations symbolically and ways to simplify expressions.  Many people use Mathematica because it removes the tedium of doing algebra with pencil and paper---and perhaps more importantly it doesn't make errors!  However, one frustrating aspect is getting Mathematica to represent an expression in exactly the form you desire.  Sometimes it is possible with patience, practice, and skill---and sometimes you have to give up and accept that the form of the expression will not be ``neat and compact.''
