with more studing i think i understand to factor out A from both terms i have to get rid of B and i do this by using A+1=1. so in long term it looks like A+A(1+B)
A+A1
A+A=A
OK still a long way to go.
What? I don't think the op is quite ready for such an advanced mathematical topic. You lost me after "Boolean lattice".A Boolean algebra is also called a Boolean lattice. The connection to lattices (special partially ordered sets) is suggested by the parallel between set inclusion, A ⊆ B, and ordering, a ≤ b. Consider the lattice of all subsets of {x,y,z}, ordered by set inclusion. This Boolean lattice is a partially ordered set in which, say, {x} ≤ {x,y}. Any two lattice elements, say p = {x,y} and q = {y,z}, have a least upper bound, here {x,y,z}, and a greatest lower bound, here {y}.

I think it's called "showing off".
