In Boolean functions and propositional calculus, the Sheffer stroke denotes a logical operation that is equivalent to the negation of the conjunction operation, expressed in ordinary language as "not both". It is also called nand or the alternative denial, since it says in effect that at least one of its operands is false. In digital electronics, it corresponds to the NAND gate. It is named after Henry M. Sheffer and written as ↑ or as |. In Bocheński notation it can be written as Dpq.
In mathematics, a Sheffer sequence or poweroid is a polynomial sequence, i.e., a sequence {pn(x) : n = 0, 1, 2, 3, ... } of polynomials in which the index of each polynomial equals its degree, satisfying conditions related to the umbral calculus in combinatorics. They are named for Isador M. Sheffer.

The NAND Boolean function has the property of functional completeness. This means, any Boolean expression can be re-expressed by an equivalent expression utilizing only NAND operations. For example, the function NOT(x) may be equivalently expressed as NAND(x,x). In the field of digital electronic circuits, this implies that we can implement any Boolean function using just NAND gates.
