View Full Version : Truth Table Question
01-25-2006, 07:24 PM
Please could somebody advise me on my query about truth tables?
NOT (NOT A AND B) as shown below
A OR NOT B mean the same thing?
This was part of a question in an assignment that I had to submit by yesterday, which I did, but unfortunately I still don't think I have the gist of this!
Thank you in advance.:confused:
Dpending on which you want to use, then the answer is 'yes' or 'no', but I forget which way round. If you have a textbook for this, then it will probably tell you, as I think this was an example of the difference on our course.
I could, of course, be getting confed, and this might all be wrong.

Thanks for trying to help though.
Will show whether the statement:
is always true (i.e. each side is the same)

:thumbsup: Hi GJay,
Thank you for your coding, I really appreciate your help.
Just use DeMoivre's theorem:
!(!A & B) = !!A | !B = A | !B
Thus, NOT (NOT a AND b) is equivalent to: a OR NOT b
