Play with this app and build some proofs in natural deduction style. Clicking on a formula automatically expands it with possible rules. Assumptions are printed in blue. Selected one of them generates a new subtree. Attaching two trees is done by dragging the root of the first one to the leaf of the second one. If there only one possibility, this attachment is performed automatically. The ...

I'm going to define a function S of n and I'm going to define it as the sum of all positive integers including N. And so the domain of this function is really all positive integers - N has to be a positive integer.

Natural Deduction for Logics of Ground ( ) if σi is not the conclusion of Π then σi is a premiss to an introduction rule or σi is ⊥ ( ) for all j > i, if j , n, then σj is a premiss of an introduction-rule and if the introduction rule is a full ground introduction rule, then σj is a subformula of σj+ .

The set of the implemented operations allows for inference of formulas using the laws of natural deduction. The system can also detect whether a certain proposition acan be deduced from the basic facts and given rules. The whole protocol is fully autonomous; that is, after introducing the initial set of molecules, no human assistance is needed.

"The Daemon Proof Checker checks [logic] proofs and can provide hints for students attempting to construct proofs in a natural deduction system for sentential (propositional) and first-order predicate (quantifier) logic.
