History of Islamic Mathematics (Numerical System)
History:— The modern numerical system of 1,2,3,4,5,6,7,8, and 9; were a unique set of numbers invented by Spanish Muslims.[1] and were based on the angles they made.[2] The Indian numerical system, it's inspiration, underwent several drastic changes before this new system was created over the course of a few centuries (969—c. 1300s). This was because the Indian numerical system was primitive and problematic to use; requiring the use of physical equipment, not pen and paper, which was a major disadvantage when it came to it's practicality; Hassan al-Uqlidisi for instance wrote, that the "[o]ficial scribes nevertheless avoid using [the Indian system] because it requires equipment [like a dust board] and they consider that a system that requires nothing but the members of the body [ie their own body parts] is more secure and more fitting to the dignity of a leader.".[3] As a result he invented new methods,[n. 1] as a way to solve for problems using only pen-and-paper-algorithms he himself developed,[4] and thus became the first person in history to thus do so.[n. 2] The Indian numerical system was mainly used by astrologer mystics, and was similarly like the Chinese system based on 10s.[5] By the 1300's, the Eastern Arabic numerals underwent another revolutionary change in the Western Arabic territories to what they look like today; the Ghubar/Western Arabic numericals.[6] Even according to the "National Institute of Sciences of India" (1962), "The[se] Ghubar numerals resemble modern European numerals much more closely than do the Hindu numerals".[7] Therefore it is incorrect to call modern numerals "Hindu numerals".[n. 3] |

- The Indian numerical system never used pen-and-paper style algorithmic arithmetic:
- Historians note that "[f]rom their origins in the late eighth and early ninth centuries, the numerals spread throughout the Islamic world, though not without resistance or confusion. Many conservative scribes and bookkeepers resisted the new numerals in favour of older calculation on the fingers and with numerical words.
- Historians say "[t]he Arabs borrowed not only the Indian numerals, but also a host of computational techniques and devices, including the dust-board, a flat tablet strewn with sand into which figures could be written for undertaking computations...Other techniques available included complex Greek-derived system of finger reckoning and the use of shells; accordingly, the use of written pen-and-paper-arithmetic was apparently not part of the initial practice of Indian derived numeration."
- After the work of al-Uqlidisi, only then did pen-and-paper-arithmetic began to be widely used, the same time; well after his algorithms on pen-and-paper arithmetic been published and disseminated across the world; "[y]et once the [treatise] had been established by the eleventh and twelfth centuries, Arabic mathematical texts began to advocate doing computations with paper and ink instead of the dust-board".
