Logical AND

Notation

And is usually denoted by an infix operator: in mathematics and logic, it is denoted by a "wedge" ${\displaystyle \wedge }$ (Unicode U+2227 ∧LOGICAL AND), ${\displaystyle \&}$ or ${\displaystyle \times }$; in electronics, ${\displaystyle \cdot }$; and in programming languages &, &&, or and. In Jan Łukasiewicz's prefix notation for logic, the operator is ${\displaystyle K}$, for Polish koniunkcja.
