Center node: "three datatype defining rewrite systems for datatypes of integers each extending a datatype of naturals"
  Abstract: AbstractInteger arithmetic is speciﬁed according to three views: un ary, binary, and decimal notation. Ineach case we ﬁnd a ground conﬂuent and terminating datatype d eﬁning rewrite system. In each casethe resulting datatype is a canonical term algebra which extends a corresponding canonical termalgebra for natural numbers.Keywords and phrases: Equational speciﬁcation, initial algebra, datatype deﬁni ng rewriting system,abstract data type.
