• Resumen

  • When asked, a number of students answer zero factorial to be zero as a continuation to the answer of one factorial to be one. Any instructor would then seek a justification of zero factorial to be one from computing nCnvia the well- known combination formula. This article conveys a simple presentation of zero factorial to be one based on lower and upper bounds of nfactorial. We have not seen this explanation covered in any algebra textbook.
