I can't find what are you asking so I want to share what I know about Boolean algebra as Boolean logic is a system of symbolic logic which is used in computers.Study of mathematical operations performed on binary variables that can have only two values: true or false. It provides a set of rules called Boolean logic that are indispensable in digital computer-circuit and switching-circuit design.
How to Graph Linear Equations
If you're doing this for a course, then you'll really need to know this. Giving you the answers wouldn't help you. Go to your book and read the definition of a Boolean algebra. The answers here comes right out of that definition. (Hint: There are 2 boxes to check.)
some hints:
what is a+0, by the definition of 0? are + and * commutative? (this should be in your book, somewhere).
