Or

And is a logical binary operation which takes two values of the set of $\mathbb{Z}/2$ and applies the “disjunction” function which only returns 0 only if both operands are 0 and otherwise returns 1.

The operation is noted as $\vee$ throughout my work. \lor in LaTeX.

Arg 1	Arg 2	Return
$1$	$1$	$1$
$1$	$0$	$1$
$0$	$1$	$1$
$0$	$0$	$0$
