yes. (A')' = A

therefor, your statement

(A' ^ B')' = (A')' v (B')'

is correct. Same with the second.

DeMorgan: (A v B)' = A' ^ B', (A ^ B)' = A' v B'

(the other thing is A v A' <=> w resp. B ^ B' <=> f)

(all the while assuming with ' you mean "not"..)

That's what I thought, but it seems as if the second method is off. Atleast that's what my friend told me not to do on the mid-term, unable to explain why.

well, if unsure, just make a table.

Start with A and B, then "calculate" A', B'

having that, you go on with calculating (A' ^ B')' and A v B and you see it's the same!

BTW: your two 2. are basically the same because (A')' = A (not not = nothing)

ok now that i understand that, could you explain your signature?:tongue:

:tongue: so in the beginning, there was a bee. :rolleyes:

What else could I explain? I have nothing to do today *g*

10 = 2 in binary

Thus he means that there is 2 type of people in world, one that can read binary, the other that cannot.

oh i thought he was talking about two humans in the begining...
