Logic

Definition: a logical variable is a variable that is either true or false (boolean).

Logical Operators

• $\wedge$ - AND - P is True AND Q is True
• $\vee$ - OR - P is True Or Q is True
• $\neg$ - NOT - P is NOT True

Definition: a logical statement is a True or False statement made up of logical operators and variables.

Definition: conditional $ p \rightarrow q $; “if P is True, we can deduce that Q is True.” So if P if False, the statement doesn’t owe use shit and no longer applies.
