    AvB = A AND B?
    ¬(AvB) = NOT (A AND B)?
    A^B = A OR B?
    ¬(AvB) v (A^B) = NOT(A AND B) AND (A OR B)

    Is this right?

    Not quite: ∧ is logical conjunction (AND) whilst ∨ is logical disjunction (OR). You're right, though, that ¬ is logical negation (NOT), alternatively denoted as a bar above.

    AND and OR are the wrong way round but besides that you're good to go.

    I learned it as a line above, myself.

    Then again, I've written more logic in C than I have on paper, so I'm probably more used to !, && and ||.

    Me too, actually; I've always preferred that as a more compact grouping. Luckily assessments don't seem to care, considering the 'preferred' notation changes between fields :rolleyes:

    Yep. I learned boolean algebra when studying electronics, so the notation I know natively is (IIRC) a cross for OR and a circle for AND. I prefer diagrams though; there's less arguing about thouse :lol:
