DESCRIPTION:Notation in medieval Arabic algebra\n\nAbstract\n\nArabic algeb
 ra had been practiced for over three centuries before a notation specific 
 to the art emerged in the twelfth century in the Maghreb. To properly unde
 rstand how the notation functioned it is necessary to situate it in its cu
 ltural and mathematical context. From the perspective of culture this incl
 udes the relationship between books\, memorization\, and recitation\, as w
 ell as the ways people performed calculations in medieval Arabic societies
 . Mathematically one must take into account that premodern algebraists con
 ceived of polynomials differently than we do today. Where our 3x2 + 4 enta
 ils the operations of addition\, multiplication\, and exponentiation\, the
  medieval equivalent “three māls and four dirhams”\, whether rhetorical or
  in notation\, was conceived as an aggregation of seven objects of two dif
 ferent kinds with no operations present. The Arabic algebraic notation was
  created with this “aggregations” interpretation in mind\, and was practic
 ed according to their relationship with books and writing. \n
