    calculated column =
table1[X] - RELATED ( table2[Y] )

    If 1:many, the following formula should work.

    calculated column =

You are asking very general questions, so it is hard to know what you are trying to do, or why.  My experience is that most calculated columns that new users try to build are completetly un-necessary and probably worse still - it normally is the wrong approach.  Read my article here, then see if you can do what you want with measures.
