John Knightley responded to what you wrote.  Nobody asserted that you 
claimed this usage was standard in China.  The part about Chinese math 
notation was informational.

If anyone wants to prove that CJK ideographs get used in superscript 
fashion, all that's needed is one published example.  But it cannot be 
disproved because of a thing called 'negative proof'.  Just because 
something can't be disproved doesn't make it true; it only means your 
hat is safe.
