That's the classic Boolean algebraic notation. In basic algebra, the two interesting operations are "addition" and "multiplication". Boolean math works like elementary arithmetics, with the exception that 1 + 1 = 1 I'm guessing the modern symbols ∨ and ∧ were derived from the set-theoretical analogues, ∪ and ∩, which were also formerly used for the same purpose.
