Question

1. Distributive Property x+yz = (x+y)(x+z) I don't understand how to go from the left-hand-side(LHS) to the (RHS). First, I would expand via FOIL: xx+xz+xy+yz where 'xx' can be simplified to just 'x': x+xz+xy+yz and at this point we can factor out an x: x(1+z+y)+yz I also understand that since there is a 1 being added to the the expression on the inside, it can be simplified to: x(1)+yz and is equivalent to: x+yz. Question 1: How can I go from the LHS to the RHS? I'm told it is very useful to know how to manipulate it into various equivalent forms. Question 2: There are no parentheses in the expression on the LHS which confuses me. Which operation comes first? 2. DeMorgan's Theorem x+x'y = x+y (Where x' denotes "Not x") Question 3: Which operation comes first? Again no bracket.
