NAND

⊼ is NAND: it rules out the “both true” case. It appears in logic and circuit design. The one-operation idea predates this glyph.

What ⊼ means

NAND means “not both”: false only when both inputs are true.

For A and B, A ⊼ B is false only when both are true, and true for every other pairing. A NAND gate checks whether both inputs are true, then flips that result. NAND gates can implement any Boolean function.

Peirce described a logic built from one operation in an 1880 manuscript; Sheffer published a related Boolean-algebra system in 1913. Boolean algebra is math with true and false values. Sheffer's vertical-bar notation is the Sheffer stroke; the Peirce arrow is related NOR, true only when neither input is true.

Technical notation for Boolean logic and circuit design.

NAND is not NOR: false only for two true inputs.

Questions people ask

Why does ⊼ show as a box?

Font support. A font without this text glyph may show a missing-glyph box or fallback; its logic is unchanged.
