both. Then this must mean that AB , in fact, is zero i.e., 1 · 0 = 0 .
Not exactly, since A is or''d with A AND B, it reduces to simply A. Draw out a truth diagram and look at it.
let X = A and B let V = A or X A B X V 0 0 0 0 1 0 0 1 0 1 0 0 1 1 1 1Can you see that V = A or A and B is equal to A?
I assume + means or here, I am unfamiliar with using the + symbol in boolean algebra.
