This follows from the fact that a conditional with a contradictory antecedent that does not share any propositional or predicate letters with the consequent cannot be true ( or derivable ).

In propositional logic, material implication is a valid rule of replacement that allows for a conditional statement to be replaced by a disjunction if and only if the antecedent is negated.

In propositional logic, transposition is a valid rule of replacement that permits one to switch the antecedent with the consequent of a conditional statement in a logical proof if they are also both negated.

While it is one of the most commonly used concepts in logic it must not be mistaken for a logical law ; rather, it is one of the accepted mechanisms for the construction of deductive proofs that includes the " rule of definition " and the " rule of substitution " Modus ponens allows one to eliminate a conditional statement from a logical proof or argument ( the antecedents ) and thereby not carry these antecedents forward in an ever-lengthening string of symbols ; for this reason modus ponens is sometimes called the rule of detachment.

There are three main classes of instruction: arithmetic, logical, and move ; conditional jump ; conditional skip ( which may have side effects ).

In particular, note that if the domain of discourse is restricted to consist only of those objects that satisfy a certain predicate, then for universal quantification this requires a logical conditional.

Here the " if ... then " construction indicates the logical conditional.

For example, substituting propositions in natural language for logical variables, the inverse of the conditional proposition, " If it's raining, then Sam will meet Jack at the movies " is " If it's not raining, then Sam will not meet Jack at the movies.

Since a double negation has no logical effect, the inverse of the inverse is logically equivalent to the original conditional.

In natural languages, an indicative conditional is the logical operation given by statements of the form " If A then B ".

In most logical systems, negation, material conditional and false are related as:

The instruction set was minimal, but supported the basic set of arithmetic and logical operations, as well as conditional and relative jumps ( making it possible to write a library of subroutines ).

The material conditional, ( also known as material implication ) is a logical binary compound using a logical connective often symbolized by a forward arrow "→", and often simply called a conditional.

The truth table associated with the material conditional not p or q ( symbolized as p → q ) and the logical implication p implies q ( symbolized as p → q, or Cpq ) is as follows:

Others have noted that the strict conditional cannot adequately express counterfactual conditionals, and that it does not satisfy certain logical properties.

Modern logical constructs, however, allow for conditional logic (" If Martians existed ...").

The first version of FORTRAN ( 1957 ) and its successor FORTRAN II ( 1958 ) did not have logical values or operations ; even the conditional statement took an arithmetic expression and branched to one of three locations according to its sign.

Instead, conditional constructs like assume that the logical value " false " is represented by the empty list, which is defined to be the same as the special atom or ; whereas any other s-expression is interpreted as " true ".

By definition, all comparisons, logical operations, and conditional statements applied to and / or yielded values.

Besides studying logical puzzles and paradoxes, the Dialecticians made two important logical innovations, by re-examining modal logic, and by starting an important debate on the nature of conditional statements.
