RE: Operation Precedence questions

I always use the parenthesis. It just makes it easier to read for me.


Thanks,

Mark

Take it from someone who went Ga-Ga in School over Boolean Math -
Parentheses change everything. Try A and B or C and D versus (A and B) or
(C
and D). Stuff in Parenthesis is always evaluated first. I tend to use lots
of them 'cause I'm still confused by AND/OR precidence and get even more
confused when you throw in a NOT. Consider A or B and C or NOT D. <Hair

If it is, I didn't see it in that chapter!  Doesn't that rule apply to
expressions inside
parentheses?
