What is the history of natural numbers? - Answers
Set-theoretical definitions of natural numbers were initiated by Frege. He initially defined a natural number as the class of all sets that are in one-to-one correspondence with a particular set. However, this definition turned out to lead to paradoxes, including Russell's paradox. Ver más In mathematics, the natural numbers are the numbers 1, 2, 3, etc., possibly including 0 as well. Some definitions, including the standard ISO 80000-2, begin the natural numbers with 0, corresponding to the non-negative integers 0, … Ver más The set of all natural numbers is standardly denoted N or $${\displaystyle \mathbb {N} .}$$ Older texts have occasionally employed J as the symbol for this set.
