    Re: Implication and Equivalence basics

    I cracked it!!

    I spent some serious hours on it and I finally did the end of section quiz and got 70% - I'm so chuffed.

    There are still many issues in terms of my understanding but I've mastered this one so there you go!

    I am glad that you cracked it whatever it is??

    Despite having been asked repeatedly, you steadfastly refused to tell us exactly what you were trying to do. If we don't know or understand what it is that you are required to do, how can we possibly help you?
    Thanks from topsquark

    I've still no idea how to upload pictures to this site. Like I said I couldn't find a FAQ area to be able to learn how to do it.

    What does that comment have anything to do with your not telling us the exact problem you are working on. You do not need symbols.

    Here are some examples.
    1) How is "If p then q" equivalent to "Not p or q"?
    2) How is the negation of "If p then q" equivalent to "p and not q"?
    3) How is "If p then q" equivalent to "q is necessary for p"?
    4) How is "If p then q" equivalent to "p only if q"?

    There is no excuse for not simply stating the question in easy to read English. Or is there?
