I was doing the following question. Using the following rules of boolean algebra:
_ law 1: X+X=1 law 2: X.1=X law 3:X.Y+X.Z = X.(Y+Z)
simplify:
__ _ __ ABC+ABC+ABC+ABC
I have tried to simplify starting off with law 1, but I get stuck because the complements somewhat confuse me.
The bar meaning complement or 'not'
Could someone explain?
