I have only run into George Boole, Boolean algebra and booleans in engineering textbooks (digital electronics, software programming). IIRC, they *always* used the multiplication and addition symbols. When studying symbolic logic, I never ran into that notation or Boole or Boolean algebra or booleans. For example, ∧ and ∨ are called connectors instead of operations. IOW, they are symbols of a language instead of functions. Marko -- https://mail.python.org/mailman/listinfo/python-list
