propositional variables

Propositional variables are symbols used in logic to represent statements that can be either true or false. Think of them as placeholders for specific facts or assertions, like "It’s raining" or "The door is open." These variables aren’t about the actual content of the statement but about its truth value. By combining propositional variables with logical connectives (like AND, OR, NOT), we can analyze and determine the truth of complex statements systematically. They provide a structured way to work with and reason about different assertions in logic and mathematics.
