In mathematics and mathematical logic, Boolean algebra is the branch of algebra in which the values of the variables are the truth valuestrue and false, usually denoted 1 and 0 respectively. Instead of elementary algebra where the values of the variables are numbers, and the main operations are addition and multiplication, the main operations of Boolean algebra are the conjunctionand, denoted ∧, the disjunctionor, denoted ∨, and the negationnot, denoted ¬. It is thus a formalism for describing logical relations in the same way that ordinary algebra describes numeric relations.
She then feeds the list into a complex keyword-searching strategy called a Boolean search string ... the proximity to anything of note to draw people in," and be optimized for Google searches, he said.
