In this way the propositional calculus can be discarded entirely.

This usage is demonstrated in the article on propositional calculus.

In fact the sign comes into the propositional calculus when a formula is to be evaluated.

Using the symbols of propositional calculus, this would become .

But in 1936, the need for the new propositional calculus was demonstrated through several proofs.

Applications include the propositional calculus and the theory of digital circuits.

The propositional calculus then defines an argument as a set of propositions.

It is not that these rules are contentious, when applied in conventional propositional calculus.

Most of these symbols can be found in propositional calculus, a formal system described as .

The propositional calculus gives us a very simple Scott information system as follows:

The following "laws" of the propositional calculus are used to "reduce" complex formulas.

Sheffer's result was, however, restricted to the propositional calculus, and so, of limited significance.

Thus Mentalese is best expressed through predicate and propositional calculus.

Any logical expression of classical propositional calculus can be naturally represented by a tree structure.

Thus, Boolean logic is sometimes used to denote propositional calculus performed in this way.

There are many examples of sound Frege rules on the Propositional calculus page.

Propositional calculus is about the simplest kind of logical calculus in current use.

This is expressed in a propositional calculus as logical equivalence of certain compound statements.

In particular, checking whether entails in this condition can be done using the rules of the propositional calculus.

Fortunately, the lovers did have Boolean algebra and propositional calculus at their disposal.

These logics often require calculational devices quite distinct from propositional calculus.

The following outlines a standard propositional calculus.

A propositional calculus is a formal system , where:

Truth-functional propositional calculus is a formal system whose formulas may be interpreted as either true or false.

The formula is provably true in intuitionist propositional calculus.
