The Sexagesimal numeral system gives us our hours, minutes, and seconds.
Yuki octal numbers came about from counting,
instead of the fingers themselves, the spaces between the fingers,
perhaps because the spaces resembled containers better.
There is nothing inherently advantageous about decimal numbers.
Computer systems use binary (because a switch may be only on or off),
and computer programmers use octal and hexadecimal
as logical groupings for binary code,
which work because 8 and 16 are powers of 2.
