Video Orientation to the University of Pennsylvania Library's LJS 481, a commentary on the summary of arithmetical operations by the late 13th- and early 14th-century scholar Ibn al-Bannāʼ. Demonstrates with examples the calculation of sums involving fractional numbers and square roots. Extensive marginal notes on a few leaves (p. 20-35). The first leaf is missing and the text ends abruptly. Several leaves have restored outer margins. Pages 189-194 missing text because of conservation after water damage. Written in northern Africa, probably Morocco, in the 15th or 16th century.
