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.
