| 1. | In this way the propositional calculus can be discarded entirely.
|
| 2. | The underlying logic is classical propositional calculus and classical predicate calculus with equality.
|
| 3. | This is expressed in a propositional calculus as logical equivalence of certain compound statements.
|
| 4. | Our propositional calculus has ten inference rules.
|
| 5. | Modal logic also offers a variety of inferences that cannot be captured in propositional calculus.
|
| 6. | It is not that these rules are contentious, when applied in conventional propositional calculus.
|
| 7. | In fact the sign comes into the propositional calculus when a formula is to be evaluated.
|
| 8. | RHS ( in propositional calculus ), then LHS = RHS ( in Boolean algebra ).
|
| 9. | Classical propositional calculus as described above is equivalent to intuitionistic propositional calculus is equivalent to Heyting algebra.
|
| 10. | Classical propositional calculus as described above is equivalent to intuitionistic propositional calculus is equivalent to Heyting algebra.
