		Definition of natural numbers in English: natural numbersplural noun The positive integers (whole numbers) 1, 2, 3, etc., and sometimes zero as well.  Example sentencesExamples -  In particular he showed that if any countable set has an arithmetic where the elements have unique decompositions into primes, then it is isomorphic to the arithmetic of the natural numbers.
 -  In 1889 Peano published his famous axioms, called Peano axioms, which defined the natural numbers in terms of sets.
 -  In contrast, Fermat had managed to show that you couldn't find natural numbers with a + b = c, using a method he called steepest descent.
 -  Cantor proves that the algebraic real numbers are in one-one correspondence with the natural numbers in the following way.
 -  This means that the natural numbers, the integers, and the even integers all have the ‘same number’ of elements.
 -  For what they thought they had done was establish a deep result about how the primes are distributed among the natural numbers.
