OriginEdit

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

MintermsEdit

For a boolean function of   variables  , 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.
