Are there any countries that don't use base 10 mathematics?

Question

Any modern-day civilizations that might use a different base?

The Mayans used the base 20 system (ten fingers and ten toes)

Answer 1

None that I know of currently. In all but the most isolated, primitive societies, the base 10 is used. (Of course computers use base 2, but they hardly qualify as a civilization.)

There is prehistoric evidence that a few tribes used a base 5 system; the Romans had a complex system that was very loosely based on 10, and the ancient Mayan civilization used base 60!

Answer 2

There are dozens and dozens of tribal cultures scattered about the globe that do not use a decimal system, but there are not any actual countries (that I'm aware of) where a non-decimal numeral system is currently both widespread and relatively uniform among the people.

If you're interested, here is a link to a brief description of some of the Pacific Islander cultures' numeral systems:

Of course, the cultures here are just that--small pockets of indigenous culture that have somehow managed to remain free of outside influence; they are not "countries," and these civilizations' cultures are rapidly disappearing along with their highly unique numeral systems.

Answer 3

Countries advanced in computer technology make extensive use of base 2 (binary) and base 16 (hexadecimal) Base 10 mathematics is really awkward in computers which are binary based, or, at least, the conversions are awkward.

Answer 4

If there are, they aren't very advanced. Either that or they don't have 10 fingers. If we had 8 fingers then we'd be using a base 8 system.
