logical operation

In logic, a logical connective, also called a truth-functional connective, ' logical operator or propositional operator, is a logical constant which represents a syntactic operation on a sentence, or the symbol for such an operation that corresponds to an operation on the logical values of those sentences. A logical connective serves to produce a compound sentence from one or two other sentences. The truth value of the resultant compound sentence is determined by the truth-values(s) of the one or two other sentences. Consequently a logical connective can be seen as a function which when applied to sentences as arguments whose values are True or False returns in turn the value True or False; consequently logical connectives are called truth-functional connectives.
