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 predicate-logic.
