Symbolic logic is the area of mathematics which studies the purely formal properties of strings of symbols. Mathematics is the body of Knowledge and Academic discipline that studies such concepts as Quantity, Structure, Space and The interest in this area springs from two sources. First, the symbols used in symbolic logic can be seen as representing the words used in philosophical logic. Logic is the study of the principles of valid demonstration and Inference. Second, the rules for manipulating symbols found in symbolic logic can be implemented on a computing machine. A computer is a Machine that manipulates data according to a list of instructions.
Symbolic logic is usually divided into two subfields, propositional logic and predicate logic. This is a technical mathematical article about the area of mathematical logic variously known as "propositional calculus" or "propositional logic" In Mathematical logic, predicate logic is the generic term for symbolic Formal systems like First-order logic, Second-order logic, Many-sorted
Modern mathematical areas arising out of formal logic are grouped under the heading mathematical logic. Mathematical logic is a subfield of Logic and Mathematics with close connections to Computer science and Philosophical logic. Mathematical logic is a subfield of Logic and Mathematics with close connections to Computer science and Philosophical logic.
Propositional logic
The area of symbolic logic called propositional logic, originally called propositional calculus but not to be confused with the school subject calculus, studies the properties of sentences formed from constants, usually designated A, B, C, . This is a technical mathematical article about the area of mathematical logic variously known as "propositional calculus" or "propositional logic" Calculus ( Latin, calculus, a small stone used for counting is a branch of Mathematics that includes the study of limits, Derivatives . . and five logical operators, AND, OR, IMPLIES, EQUALS and NOT. Table of logic symbolsIn Logic, two sentences (either in a formal language or a natural language may be joined by means of a logical connective to form a compound sentence The corresponding logical operations are known, respectively, as conjunction, disjunction, material conditional, biconditional, and negation. In Logic and/or Mathematics, logical conjunction or and is a two-place Logical operation that results in a value of true if both of The material conditional, also known as the material implication or truth functional conditional, expresses a property of certain Conditionals in Logic In Logic and Mathematics, logical biconditional (sometimes also known as the material biconditional) is a Logical operator connecting two statements In Logic and Mathematics, negation or not is an operation on Logical values for example the logical value of a Proposition These five operators are sometimes denoted as keywords, especially in computer languages, and sometimes by special symbols (see Table of logic symbols). In Computer programming, a keyword is a Word or Identifier that has a particular meaning to the Programming language. Logical connectiveIn Logic, a set of symbols is commonly used to express logical representation All except NOT are binary operators; NOT is a unary operator which precedes its operand. The values of these operators are given by truth tables. A truth table is a Mathematical table used in Logic — specifically in connection with Boolean algebra, Boolean functions and Propositional
Predicate logic
Predicate logic, originally called predicate calculus, expands on propositional logic by the introduction of variables, usually denoted by x, y, z, or other lowercase letters, and also by the introduction of sentences containing variables, called predicates, usually denoted by an uppercase letter followed by a list of variables, such as P(x) or Q(y,z). In Mathematical logic, predicate logic is the generic term for symbolic Formal systems like First-order logic, Second-order logic, Many-sorted In addition, predicate logic allows so-called quantifiers, representing ALL and EXISTS. Quantification has two distinct meanings In Mathematics and Empirical science, it refers to human acts known as Counting and Measuring
