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:


 * $$A \wedge B$$
 * $$A \wedge (\neg B) \wedge (\neg C)$$
 * $$\neg A$$

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 $$n$$ variables $${x_1,\dots,x_n}$$, a product term in which each of the $$n$$ 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.
