Referncing a calculated column in a select?

I am creating some views, that have columns with fairly complex calculations
in them. The I want to do further calculations using the result of this
calculation. Right now, I am just duplicating the first calculation in the
select fro the 2nd calculated column. There must be a batter way to do
this, right?
