I'm looking at some class examples on basic postulates and I can't figure out how the 2nd part is reduced (see below). Could someone explain it to me?
eq:
X='a'c+ac+'ac+a'c
this is the part I do not understand, and could use some explanation using the formulas below.
= 'a('c+c) + a('c+c)
The example uses theses formulas:
[p6a] x*y = y*x [p8a] x(y+z) = x*y + x*z
and to finish it all off: (which I understand)
= 'a*1 + a*1 = 'a+a = 1
