There are the mathematician/logicians who do boolean algebra (usually as part of lattice theory). They usually use ∧ ∨ ¬ The guys who (ab)use the add/multiply notations of school algebra are the electronics books — Karnaugh maps, minimization all that stuff. One or two pages of truth tables, some of this add/mul notation and then on its all the standard logic-circuit diagrams for combinational and sequential circuits. -- https://mail.python.org/mailman/listinfo/python-list
