ab: This article presents divisibility tests, along the line of “casting out
nines”, in various numeration systems: base-10, -12, and -20, as well
as the modified base-20 scheme used in the Mayan Long Count calendar.
Since the latter incorporates factors of 3, besides 2 and 5, it often
allows simpler tests than base-10. The author gives such qualitative
comparisons a spurious precision by assigning to each numeration system
a score, given to four (decimal) significant figures.
