1. The problem statement, all variables and given/known data I'm sure you all know deMorgans law on simplifying boolean expressions, I just can't seem to get it. It doesn't make sense to me, like ([not]x.[not]y) = [not]x + [not]y]. 2. The attempt at a solution I tried it and I don't know why it doesn't work for me ie. ([not]1.[not]0) = [not]1 + [not]0 = (0.1) = 0 + 1 = 0 = 1 See my problem.
