:Hello {{u|Bennv123}} and thanks for doing this review. I added the missing citations. The exact example about the person's height is not in the source but the examples there are very similar so I hope this shouldn't be a problem.

::[[File:Symbol voting keep.svg|16px]] [[User:Bennv123|Bennv123]] ([[User talk:Bennv123|talk]]) 13:54, 21 March 2024 (UTC)
:: @[[User:Phlsph7|Phlsph7]] I think the claim "the decimal system in arithmetic was invented in India" seems a bit problematic. People were doing various kinds of positional decimal "arithmetic" for centuries before the Hindu–Arabic numeral system per se, in multiple other parts of the world. There are various more precise statements that would be accurate but perhaps too wordy for a DYK hook. –[[user:jacobolus|jacobolus]] [[User_talk:jacobolus|(t)]] 19:51, 21 March 2024 (UTC)
:::{{ping|jacobolus}} Thanks for raising this concern. From Burgin 2022, p. 13: "the main contribution of Indian mathematics to the human culture is the decimal positional numeral system ... It is India that gave us the ingenius method of expression all numbers by means of ten symbols ...". Based on the sources that I'm aware of, this claim is common. Strictly speaking, the statement that it was invented in India does not exclude the possibility that it was invented elsewhere as well. But if this is an issue, we could use the hook "... that the [[Hindu–Arabic numeral system|decimal system]] common in '''[[arithmetic]]''' was invented in India?". This would leave even more space for not-so-common decimal systems. [[User:Phlsph7|Phlsph7]] ([[User talk:Phlsph7|talk]]) 08:17, 22 March 2024 (UTC)
::::{{re|Phlsph7}} Alternatively, ALT1 can just be struck through. ALT0 and ALT2 strike me as more interesting hooks anyway. [[User:Bennv123|Bennv123]] ([[User talk:Bennv123|talk]]) 08:41, 22 March 2024 (UTC)
:::::Agreed, ALT0 and ALT2 are the better options so not much is lost by removing ALT1. [[User:Phlsph7|Phlsph7]] ([[User talk:Phlsph7|talk]]) 08:45, 22 March 2024 (UTC)</div><includeonly>|}}</includeonly><!--Please do not write below this line or remove this line. Place comments above this line.-->
