Proposition system

A proposition system is a structured framework used in logic and mathematics to analyze and evaluate statements or claims. It involves breaking down complex sentences into basic units called propositions—declarative statements that are either true or false. These propositions can be combined using logical operators like “and,” “or,” “not,” and “if-then” to form more complex expressions. The system provides rules to determine the truth value of these combined statements, helping us reason clearly and systematically about the validity of arguments, decision-making, and problem-solving in various fields such as computer science, philosophy, and mathematics.
