Typy argumentů
celé číslo PredecessorFn(celé číslo)
Axiomy (6)
"(number+2)" se rovná "(number-)".
(equal
(PredecessorFn ?NUMBER)
(SubtractionFn ?NUMBER 1))
Jestliže int je instancí třídy celé číslo, potom int se rovná "("(int+2)"+1)".
(=>
(instance ?INT Integer)
(equal
?INT
(SuccessorFn
(PredecessorFn ?INT))))
Jestliže int je instancí třídy celé číslo, potom int se rovná "("(int+1)"+2)".
(=>
(instance ?INT Integer)
(equal
?INT
(PredecessorFn
(SuccessorFn ?INT))))
Jestliže "(int1+2)" se rovná "(int2+2)", potom int1 se rovná int2.
(=>
(equal
(PredecessorFn ?INT1)
(PredecessorFn ?INT2))
(equal ?INT1 ?INT2))
Jestliže int je instancí třídy celé číslo, potom int je větší než "(int+2)".
(=>
(instance ?INT Integer)
(greaterThan
?INT
(PredecessorFn ?INT)))
Jestliže int1 je instancí třídy celé číslo a int2 je instancí třídy celé číslo, potom int2 není menší než int1 nebo "(int1+2)" není menší než int2.
(=>
(and
(instance ?INT1 Integer)
(instance ?INT2 Integer))
