        AB(1 + BC)
        1 + anything is 1.
        Answer should be AB.

        I'm pretty sure that's correct although it's been ages since I did Karnaugh maps.

        Use the boolean algebra page on wiki as a reference tool and consider:

        x V y = x + y
        x ∧ y = xy

        As per sajak you should be getting AB since.

        AB + AB(BC)

        By the law of distributivity you can also get

        AB (1 + 1(BC)) = AB(1) + AB(BC) = AB + AB(BC)

        So if you take AB(1 + 1(BC)) which is really AB(1 + (BC)) since -> x(1) is always x

        And anything + 1 is always 1 -> x + 1 = 1

        So 1 + BC = 1

        AB (1) = AB

        Hoped that helped

            Bender is on fucking crack.

            It's simple. If I gave you:
            25 + 25(x)

            You can take out the 25 and simplify it like:
            25 ( 1 + x ).

            In bolean algebra, whenever you add ANYTHING with 1, it becomes one. SAJAK + 1 = 1. BEN + 1 = 1. BENDER + 1 = 1. Get it?

            So now look at your problem:

            AB + AB(BC)

            You have two terms that are the same: AB, take out the AB and simplify:

            AB ( 1 + BC ).

            Now remember, 1 plus ANYTHING will always be 1. So 1 + BC = 1.

            AB ( 1 ) = AB
