See Mendelson's example: the two mathematical statements "x is prime" and "x is odd" are represented in propositional logic with two statement letters: A and B.Tue, 14 Apr 2026 08:23:00 GMThttps://math.stackexchange.com/questions/320437/how-to-demystify-the-axioms-of-propositional-logicThe most misunderstood element of standard propositional logic is the $\to$ symbol. It is often read as "implies," but that has human meaning that one statement follows from the other in some direct way.Fri, 17 Apr 2026 17:09:00 GMThttps://math.stackexchange.com/questions/4777259/what-is-the-difference-between-propositional-constants-propositional-variablesIt is common to represent propositional constants by A, B, and C, propositional variables by P, Q, and R, and schematic letters are often Greek letters, most often φ, ψ, and χ. I understand the gist of it, I am just stuck on this difference between mainly the (constants and the variables) and the schematic letters.Thu, 16 Apr 2026 07:38:00 GMThttps://math.stackexchange.com/questions/tagged/propositional-calculus?tab=NewestAppropriate for questions about truth tables, conjunctive and disjunctive normal forms, negation, and implication of unquantified propositions. Also for general questions about the propositional calculus itself, including its semantics and proof theory. Questions about other kinds of logic should use a different tag, such as (logic), (predicate-logic), or (first-order-logic).Tue, 07 Apr 2026 08:46:00 GMThttps://math.stackexchange.com/questions/9554/whats-the-difference-between-predicate-and-propositional-logicPropositional logic (also called sentential logic) is logic that includes sentence letters (A,B,C) and logical connectives, but not quantifiers. The semantics of propositional logic uses truth assignments to the letters to determine whether a compound propositional sentence is true. Predicate logic is usually used as a synonym for first-order logic, but sometimes it is used to refer to other ...Sat, 11 Apr 2026 20:23:00 GMThttps://math.stackexchange.com/questions/4849250/propositional-logic-resolutionFor details and proof of soundness/completeness, see e.g. Mordechai Ben-Ari, Mathematical Logic for Computer Science (Springer, 3rd ed 2012), Chapter 4 Propositional Logic: Resolution, page 82.Mon, 13 Apr 2026 19:16:00 GMThttps://math.stackexchange.com/questions/4507560/is-a-propositional-variable-a-proposition1 Firstly, calling a propositional variable a proposition is prone to induce complications, at least, conceptually, if not operationally, for there is a clear difference between stating that (a variable) p and stating that $2$ is the smallest prime number; hence, better to avoid it.Sat, 18 Apr 2026 09:59:00 GMThttps://math.stackexchange.com/questions/258602/what-is-validity-and-satisfiability-in-a-propositional-statementA propositional logic is said to be satisfiable if its either a tautology or contingency. Hence if a logic is a contradiction then it is said to be unsatisfiable.Sat, 18 Apr 2026 12:07:00 GMThttps://math.stackexchange.com/questions/491856/translating-sentences-into-propositional-logic-formulasPropositional logic is unable to express moral judgements or desirability. It is possible that the point of the exercise is to let you discover for yourself some problems that modal logics attempt to address (especially if there's modal logic later in your course).Wed, 08 Apr 2026 17:06:00 GMThttps://math.stackexchange.com/questions/768757/propositional-logic-proof-using-i-p-or-c-p-or-rules-of-inferenceI'm attempting to solve a proof my professor asked. We are able to use any of the rules of inference, Indirect Proof or Conditional Proof. Every time I think am making progress I run into a brick w...Sun, 19 Apr 2026 22:36:00 GMT
