Intresting facts: 1. Fibonacci didn't invent the series named after him. He was merely copying it from the Indians he came in contact. He himself admitted this

Intresting facts: 1. Fibonacci didn't invent the series named after him. He was merely copying it from the Indians he came in contact. He himself admitted this 2. Hindu arabic numerals are just Hindu numerals. Arabs didn't add anything. Roman numerals reached the world due to Beitish but they aren't called British-Roman numerals.

Not doubting these points, but you should always cite peer-reviewed or otherwise verified sources. It makes all the difference between a fact and an opinion. This is especially true when contradicting a widely held belief. Without a verifiable source, these are just "interesting hypotheses".

  I am glad you asked, here are the references. 1. Please read "Liber Abaci". It is right there in the prologue section. Hard to find a free copy of this link hence posting a link to tweet[1] with screenshot of the relevent page. You can also cross verify with Italian version on archive.org[2] 2. Same story repeat itself with Indian numbers and algorithms.[3][4] [1] https://twitter.com/TIinExile/status/1198526477026807809 https://twitter.com/TIinExile/status/1198526477026807809 [2] https://archive.org/details/LiberAbaci/page/n5/mode/2up https://archive.org/details/LiberAbaci/page/n5/mode/2up [3] https://twitter.com/TIinExile/status/1180777105778307072 https://twitter.com/TIinExile/status/1180777105778307072 [4] http://kutubltd.com/book-details.aspx?CID=11&ID=30591 http://kutubltd.com/book-details.aspx?CID=11&ID=30591

Yeah, many hindu digits are ostensibly by inspection the origin of the Latin digits we use today in the west, while the Persians and Arabs adapted the system to their own writing (which you can also tell by looking at the actual arabic digit system which has different glyphs but orders the numbers the same way the Hindus did — so numbers are written little endian in Arabic but spoken big endian like everyone else). They are quite reasonably referred to as hindu-arabic simply because the Islamic scholars introduced them to Europe. Likewise we ought to refer to most of Greek philosophy, poetry, and literature as “Greek-Arabic” as without the Islamic scholars who preserved it very little would have survived.
