I know the "~" means not , but I don't really understand it.. @mathmale

OpenStudy (mathmale):

You're speaking of logic. That tilde (~) signifies NOT. This sort of proof is not among my strengths, but I think it safe to say that if p is a statement (such as "mathmale is fat"), then ~p signifies the opposite (which here would be mathmale is NOT fat). Hope this helps. In your shoes I'd look up "mathematical logic" on the 'Net. Best of luck to you.

OpenStudy (aum):

Is the "v" the union symbol ?

OpenStudy (tkhunny):

p = A Midsummer Night's Dream is not a type of ice cream. ~p = A Midsummer Night's Dream is a type of ice cream. q = The Scarlet Letter is a book. ~q = The Scarlet Letter is not a book. Which amongst these four statements have you? "A Midsummer Night's Dream is a type of ice cream, or The Scarlet Letter is a book." ~p ∨ q

OpenStudy (anonymous):

I have, however, I don't understand how the "~" is being used in this statement. @aum The "v" means "or" , however with logic there is also this symbol "^" which means "and" . Honestly, I'm only confused on the "~" part...

@tkhunny Perfect! I understand it now! ~p v q :D Thank you so much, just needed those examples and that clarification! I greatly appreciate it!
