For use of the minus sign, I don't have one at hand, but a quick Google seach comes up with: http://www.csee.umbc.edu/~artola/fall02/BooleanAlgebra.ppt It is more common to use a superscript `c`, but that's just a notational issue. For multiplication, addition, and dot, you can see Ki Hang Kim's Boolean matrix Theory and Applications. Applications are endless and include graph theory and (then naturally) circuit design.
