We can see the culture-based differences between tallying in Europe (where
people use vertical lines, something like Roman numerals), and in
Vietnam:
A different Chinese system for tallying relates writing and
counting. There a tally is built by successively adding lines. When all
five are present so is an ideograph for that word.
A more sophisticated mathematical property involving combinations
follows. It appears here in Chinese ideographs for numbers. The
relationships shown in this image were known in China
hundreds of years before "Pascal's triangle" appeared in the west .
The figure is from [1, p. 147, # 107].
Reference [1] gives many other
inventions and mathematical notions that originated
in China.
