False position method ibn Luqa (10th century), an Arab mathematician from Baalbek, Lebanon. He justified the technique by a formal, Euclidean-style geometric proof. Within the tradition of medieval 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 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, all three being mathematicians of
Midfielder look to provide deliveries into the box for teammates. On occasion, the false-10 can also function in a different manner alongside a false-9, usually in a 4–6–0 formation, disguised as either a 4–3–3 or 4–2–3–1 formation. When other forwards or false-9s drop deep and draw defenders away from the false-10s, creating space in the middle of the pitch, the false-10 will then also surprise defenders by exploiting this space and moving out of position once again, often undertaking offensive dribbling runs forward towards goal, or running on to passes from false-9s, which in turn enables them to create goalscoring opportunities
