I don't know how to read this notation.
But if you're supposed to prove it, and no conditions are given, that means that you're supposed to prove it for all A, B in... whatever set A and B are from.
I guess "." is meant to represent some form of multiplication that is not usually commutative?
Or maybe not usually associative?
