Through my world travels, I have noticed that in most countries, they use the same characters for numbers as we do in the western world. I know that some of these countries have their own language and in that language are their own characters for numbers, but they still use ours most of the time (i.e. Thai).
My friends and I have conjectured that this might have somehting to do with the spreading of technology, similar to the internet forcing all countries to use these letters in web addresses.
Does anyone have a better idea, or even a way to find out for sure?
