- diffhist Natural number 14:05 +84 103.52.135.87 talk (→Generalizations: natural numbers arise from the two uses of counting and ordering: cardinal numbers and ordinal numbers. * A natural number can be used to express the size of a finite set; more precisely, a cardinal number is a measure for the size of a set, which is even suitable for infinite sets. The numbering of cardinals usually begins at zero, to accommodate the empty set <math>\emptyset</math>. This concept of "size" relies on maps between sets, such that two sets have...)
