Pervasive SQL addition of fields where one or more may be null

I'd like to write a query that gives me ((Field A + Field B) - (Field C + Field D))

I get a blank, perhaps NULL, if any of the fields are null.  Thus Field A may be 22 but if fields C, D or E are null then the answer appears to be null.

Any Advice.
