You may need to research the history of mathematics?

"Islamic contributions to mathematics began around ad 825, when the Baghdad mathematician Muḥammad ibn Mūsā al-Khwārizmī wrote his famous treatise al-Kitāb al-mukhtaṣar fī ḥisāb al-jabr wa’l-muqābala (translated into Latin in the 12th century as Algebra et Almucabal, from which the modern term algebra is derived)."

Now you Know - Muhammad ibn .... was responsible for millions of us being tortured learning Algebra!!! Thats a WAR CRIME ++++
