# Propositional Logic
Propositional logic makes statements saying things like 'if
x, then y'. They are statements that are either **true or
false**, and have binary variables (P, Q, R, X, Y, etc...)
Here's some examples:
*If x, then y.*
$$x\rightarrow y$$
*If x and y, then z.*
$ (x \wedge y) \rightarrow z $
*Either the pump is on or the power is out.*
$ Pump \oplus \neg Power $
The pump is on and water is flowing if and only if the power
is on.
$( Pump \wedge Water) \leftrightarrow Power$
Propositional logic is expanded upon by [[Propositional
Logic]].
