The Danish number system has some traits in common with the French one,. I once commented on it in my log as follows:

"The etymology of the Danish words for 50 (halvtreds), 60 (tres), 70 (halvfjerds), 80 (firs) and 90 (halvfems) shows that we once had a numbersystem based on the number 20 (presumably invented by barefoot people). But those who learn the language now should just learn the words without doing the mathematics inherent in them. "

I believe the Ancient Sumerian and Babylonians used a sexagesimal number system, i.e a base 60 system. We still use a base 60 when we tell time,as in 60 seconds = one minute, 60 minutes=one hour.

Latin doesn't use base 10, as it can't represent zero.

I,II,III,IV,V,VI,VII,VIII,IX,X,XI,XII


That's just the written system. The spoken system is definitely base ten (with the oddity that they say e.g. "two from thirty" and "one from thirty" instead of "twenty-eight" and "twenty-nine", but the system still repeats every ten numbers).

I have found something very interesting:

多くの言語が膠着語的で、能格言語であるこ とが知られている。また、2進数ないし3進数 数詞を持つ言語が多く、このため「アボリ ニは3より多い数を数えられない」と言われ ることがあるが、これは誤りである。

It's about Australian Aboriginal languages (from Wikipedia).
I could not find the equivalent text in English.

However, They mean that Australian Aborigine people use binary or "trinary" counting system!!!

Also here in English:

Australia's aboriginal peoples counted by two, and many tribes of the African bush sent complex messages using drum signals at high and low pitches. Morse code, as well, uses two digits (dots and dashes) to represent the alphabet.

Does the fact that Japanese uses "ichi man" for 10,000 count? The numbers in that sequence are "one ten-thousand, two ten-thousand, three ten-thousand" (10,000; 20,000; 30,000), and so on.

I was wondering this as well (for Korean though, where 10,000 is also said like man/만, though the one in one ten-thousand isn't said in Korean). I think it's still considered base ten, but after 9,999 it goes up in different intervals than in English. There isn't a new word (eok/억) until 100,000,000. I have trouble counting past 99,999 (구만구천구백구십구) because I'm still not quite used to this way of counting.. but I'm pretty sure it's base ten.

Base 10 means 10 digits, 0-9, so Japanese is base 10. Computers usually use base 2, so it only has 0 and 1 as digits.

According to Wikipedia.
The Decimal system is the most common - people have 10 fingers.
There re some languages that use 5 number systems.
Khmer or Wolof.
And French uses 12.
Check Wikipedia for decimal.
