    Simplifying Boolean Expressions using the Laws of Boolean Algebra

    Awesome, thank you again so much, you were a great help to me :)

    Simplifying Boolean Expressions using the Laws of Boolean Algebra

    I`m thinking it would be applicable in the case of Z=(P+Q).(R+S)+P.(R+~R)

    Simplifying Boolean Expressions using the Laws of Boolean Algebra

    Ahh ok, thank you so much for clearing that up! It`s been driving me batty. One more quick question, if y`all don't mind. Does factoring always come before simplifications, or are there cases in which the best course of action would be to apply an identify first, and do factoring after? I`m...

    Simplifying Boolean Expressions using the Laws of Boolean Algebra

    Oh yea, I wouldn`t take the long way like that for my assignment, was just listing out the steps i was taking, so that if I made any mistakes it could be pointed out. I`m thinking the relevant identity in this case would be 1+A=1. Using that I can turn Z=PR(Q+1) into Z=PR(1) then I can...

    Simplifying Boolean Expressions using the Laws of Boolean Algebra

    Ok, I think I understand now. What I`m doing is, taking the common expression (in the above example it would be 2y) and dividing it out. So I get 2xy / 2y = x 2y / 2y = 1 Which leaves me with 2y(x+1). Similarly with the problem I originally posted PQR+PR, I divide PR out of both...

    Simplifying Boolean Expressions using the Laws of Boolean Algebra

    Aww crud, I`m sorry. I took the common terms PR, and tried applying the FOIL method (First, Outer, Inner, Last) to it. I thought that`s what factoring was D:. I suppose what I need to understand, is what needs to be done, to factor Z=PQR+PR.

    Simplifying Boolean Expressions using the Laws of Boolean Algebra

    Ahh yes, I am looking to simplify Z = PQR + PR, sorry for not being clear on that! After factoring the right side, this is what I`ve come up with. Z = Q + PP + PR + RP + RR Provided my factoring is correct, I believe I can use the Identity Law AA=A to get - Z = Q + P + PR + RP + R And then...

    Simplifying Boolean Expressions using the Laws of Boolean Algebra

    EDIT: My apologies if I started this thread in the wrong forum! Homework Statement Z = P.Q.R + P.R Where . = AND + = OR ~ = NOTHomework Equations (Commutative Law) A+B = B+A, A.B = B.A (Associate Law) (A+B)+C = A+(B+C), (A.B).C = A.(B.C) (Distributive Law) A(B+C) = AB+AC...

    News Why do countries nationalize their resources?

    The opposition is too strong for any of those things to pass. No point worrying about any of these things under the current government. I for one welcome our new Conservative overlords :-p

    News Why do countries nationalize their resources?

    Mostly I think they'd start gutting programs and cutting taxes, pull us out of Kyoto Accord, re-open the gay marriage debate. They'd probably go joining in on Bush's misadventures.

    News Why do countries nationalize their resources?

    Personally I'm relatively happy with how this turned out. The Liberals have been unseated, which was vital, and the Conservatives have a short leash on them thanks to the minority. I voted NDP but it didn't do much in my riding. Seems I'm living in a Liberal stronghold.

    No worries, it's probably only the Beta version. :D
