== Unnecessary qualifier in History section == 

 The 1st sentence of the 1st paragraph of section "Possible Chinese origin of Hindu–Arabic numeral system" starts with the statement "It has been suggested that ...". 

 The rule of Wikipaedia is that if you cannot provide a source for a claim, you should not state the claim.  Given that is the case, either the entire 1st sentence should be removed or if it is accepted, then the qualifier statement "It has been suggested" should not be necessary.  

 If no-one objects, I will remove that qualifier statement from the sentence.
