English
[edit]
Etymology
[edit]Blend of NOT + AND, by analogy with NOR reinterpreted as NOT + OR or negation + OR
Noun
[edit]NAND (plural NANDs)
- (logic) A binary operator composite of NOT AND; negation of AND function.
- 2022 August 4, William Bahn, “Boolean Algebra Laws—Delving Into Boolean Identities”, in All About Circuits[1]:
- The associativity of OR and AND is not at all obvious. It is tempting to assume that because OR and AND are commutative that they must be associative also. This is not the case, however, and some commutative Boolean operators are not associative. Examples include NAND and NOR.
