Product term

In Boolean logic, a product term is a conjunction of literals, where each literal is
either a variable or its negation.

Examples

Examples of product terms include:

Origin

The terminology comes from the similarity of AND
to multiplication as in the ring structure of Boolean rings.

Minterms

For a boolean function of variables, a product term in which each of the variables appears once is called a minterm. Thus, a minterm is a logical expression of n variables that employs only the complement operator and the conjunction operator.
