Boolean algebra

  1. Jan 31, 2013 #1
    Im trying to understand boolean algebra, I have to do the next problem using Boolean algebra and Identities for this one:

    So far this what I got:
    A + /A (A+B) = A + B
    A + /AA + /AB = A+B
    A + A + /AB = A + B
    A + A + B = A + B <-- I think A + A = A so ..
    A + B = A + B <-- Im not sure what to do after this

    hello luigihs! :smile:

    first, you should only be altering the LHS (until it equals the RHS, of course)

    second, /AA is not A … what is it? :wink:
