=== Matsayin karya sau biyu ===
 
Between the 9th and 10th centuries, the [[Misirawa|Egyptian]] mathematician Abu Kamil wrote a now-lost treatise on the use of double false position, known as the ''Book of the Two Errors'' (''Kitāb al-khaṭāʾayn''). The oldest surviving writing on double false position from the [[Gabas ta Tsakiya|Middle East]] is that of Qusta ibn Luqa (10th century), an [[Larabawa|Arab]] mathematician from Baalbek, [[Lebanon]]. He justified the technique by a formal, Euclidean-style geometric proof. Within the tradition of Golden Age Muslim mathematics, double false position was known as ''hisāb al-khaṭāʾayn'' ("reckoning by two errors"). It was used for centuries to solve practical problems such as commercial and juridical questions (estate partitions according to rules of [[Fiqhun Gadon Musulunci|Quranic inheritance]]), as well as purely recreational problems. The algorithm was often memorized with the aid of mnemonics, such as a verse attributed to Ibn al-Yasamin and balance-scale diagrams explained by al-Hassar and Ibn al-Banna, who were each mathematicians of Moroccan origin.
