Old paper on math differences across countries

I was recently reminded of a 2009 paper that discussed internationalization
(with a focus on ActiveMath): Culturally adapted mathematics education with
ActiveMath
<https://www.researchgate.net/publication/225449328_Culturally_adapted_mathematics_education_with_ActiveMath>.
It focuses more on course generation than on math notation, but it does
have a number of notational examples in the early sections that might be
useful to people trying to understand what is different in different
countries.
