In Boolean logic, a product term is a conjunction of literals, where each literal is either a variable or its negation.
Examples of product terms include: The terminology comes from the similarity of AND to multiplication as in the ring structure of Boolean rings.
, a product term in which each of the
variables appears once (in either its complemented or uncomplemented form) is called a minterm.
Thus, a minterm is a logical expression of n variables that employs only the complement operator and the conjunction operator.
