* Roman numerals could be considered a combination of base 5 and base 10. With unique symbols for 1 (I), 5 (V), 10 (X), 50 (L), 100 (C), 500 (D), and 1,000 (M). All other numbers being an additive or subtractive combination of the unique signs.

** Some languages are weirder: Arabic stays little-endian until ''100''. So "16" is ''sitta-`ashar'' (six-ten) and "36" is ''sitta-wa-thalaathuun'' (six-and-thirty), but "136" is ''mi'ah wa sitta wa thalaathuun'' (a-hundred-and-six-and-thirty). This, however, is a relatively modern construction. Like the language itself, the numbers were read from right to left; "sitta wa thalaathuun wa mi'ah" (six-and-thirty-and-hundred)

* Up until the 1970s, British currency was a mix of base 12 (12 pence to the shilling), and base 20 (20 shillings to the pound). They were the last first world nation to switch to a decimal based currency.

** When Arabic positional decimal notation (i.e. today's numbers) were first introduced in Europe, some regions passed laws against the use of "deceptive ciphers" and mandated continuing the use of "real quantities" (i.e. Roman numerals).

* In Leo Frankowski's ''The Cross Time Engineer'' series, the new civilization Conrad Stargard starts up in Medieval Europe uses base 12 mathematics, because Stargard believes it's more useful than decimal.

* The ''SchoolhouseRock'' music video for [[https://www.youtube.com/watch?v=_uJsoZheTR4 "Little Twelvetoes"]] briefly touches on the idea of what counting with a base-twelve system would be like, and demonstrates with the titular twelve-fingered alien character.
* In TheSimpsons Principal Skinner wishes he had enough funding for his school to buy, amongst other things, "math books that don't have that base 6 crap in them". This is almost certainly a reference to New Math, a way of teaching mathematics that was briefly popular in TheSixties but very rapidly fell out of favour.
