In logic, constantsare often used to denote definite objects in a logical system. The following table features the most notable of these — along with their respective example and meaning.
Similar to other fields in mathematics, variablesare used as placeholder symbols for varying entities in logic. The following table documents the most notable of these — along with their respective example and meaning.
Operators are symbols used to denote mathematical operations, which serve to take one or multiple inputs to a similar output. In logic, these operators include logical connectives from propositional/modal logic, quantifiers from predicate logic, as well as other operators related to syntactic substitution and semantic valuation.
In logic, relational symbols play a key role in turning one or multiple mathematical entities into formulas and propositions, and can occur both within a logical system or outside of it (as metalogical symbols). The following table documents the most notable of these symbols — along with their respective meaning and example. For the master list of ...
Nov 6, 2024 · The study of mathematical logic in mathematics is called mathematical logic. The basic mathematical logic used are the conjunction (∧), disjunction (∨), and negation (¬). Some other mathematical logics are implication and double implication.
Basic Mathematical logics are a negation, conjunction, and disjunction. The symbolic form of mathematical logic is, ‘~’ for negation ‘^’ for conjunction and ‘ v ‘ for disjunction. In this article, we will discuss the basic Mathematical logic with the truth table and examples. Mathematical logic is classified into four subfields. They are:

Propositions are commonly denoted by p and q, and we will use these symbols consistently throughout this page. Conjunction: The proposition 'p and q' denoted by 'p ∧ q' is true when both p and q are true and is false otherwise. The proposition p ∧ q is called the conjunction of p and q.
