Multiple input numbers (even greater than 2) are supported by applying bitwise operations successively on the intermediate results. For example, in an application of conditional elimination with citation "j,k →E", line j must be the conditional, and line k must be its antecedent, even if line k actually precedes line j in the proof. 3. is a contingency. To be precise, using this app, one can determine whether: (1) input is well-formed and, if not, why not, (2) sentences are tautologies, contradictions or contingent, (3) sets of sentences are consistent or inconsistent and (4) arguments are valid or invalid. For example, (a -> b) & a becomes true if and only if both a and b are assigned true. The Conformal EC-GXL configuration provides formal equivalence checking for custom circuits including memories.
