ordinal numbers , rankings make it possible to evaluate complex information according to

ordinal is an
ordinal number which is neither zero nor a successor
ordinal . Another way of defining a limit
ordinal is to say
Kaynak: Limit ordinalIn set theory , the successor of an
ordinal number α is the smallest
ordinal number greater than α. An
ordinal number that is a successor
