    Clarification

    Just to be clear - you're trying to prove the last line given the first two lines as premises?

    I don't understand your notation.

    What does > mean? greater than, contains?

    What does ● mean? dot product?

    What does / mean? not?

    My guess:

    You want to show the following:

    A\to(R\to S)
    (A\vee B)\to\{[R\to(R\land S)]\to T\}
    -----
    \therefore A\to T

    Is that correct?
