Theorem ndmaovdistr 28067
Description: Any operation is distributive outside its domain. In contrast to ndmovdistr 6009 where it is required that the operation's domain doesn't contain the empty set (
-.  (/)  e.  S), no additional assumption is required. (Contributed by Alexander van der Vekens, 26-May-2017.)
