Synopsis

The author is the first Spanish Arab so far known whose arithmetic has come down to us in full. This is probably he wrote it in Damascus. It represent Arabic arithmetic when ways have been found to obviate the Indian dust-board, but the board itself has not yet disappeared. Furthermore, the Marasim includes topics not found in such detail in other Arabic work.
