Discrete math, convert expression to NOT, AND, OR. I'm confused about what the question is asking. I wont be able to get help from my professor until tomorrow so maybe someone can help me. I will give a simpler example below.

Question

anonymous · Answer

(P & Q) is it possible to do the operations above on this statement?

anonymous · Answer

$P\land Q$ is already an "and" expression

anonymous · Answer

Ya that's what I didn't understand about the question. I just think it's worded incorrectly. I have a larger compound statement q -> ( p v r ). He says to convert it to NOT, AND, OR. Any idea now? Thanks!

anonymous · Answer

yeah in general $P\to Q \equiv \lnot Q \lor P$

anonymous · Answer

Ahh maybe the question is just asking to use the general identities to somehow have NOT AND OR instead of the implication.

anonymous · Answer

whoa whoa i got that backwards sorry
damn

anonymous · Answer

it should have been 
$$P\to Q \equiv \lnot P \lor Q$$

anonymous · Answer

it's ok :).

anonymous · Answer

so the first step in what you wrote above, (lets see if i can not screw this up) is 
$$q\to (p\lor v)\equiv \lnot q \lor (p\lor v)$$

anonymous · Answer

for "or" statements the parenthese are not necessary, so you can simply write 
$$\lnot q \lor p \lor v$$
