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.
