The word algebra comes from a word, “al-Jabr” used by Muḥammad ibn Mūsā al-Khwārizmī (Around 750-850 AD) in a book he wrote that systematically described the solutions of linear and quadratic problems by reducing them to simpler problems.
He worked in Baghdad as a scholar at the House of Wisdom established by Caliph al-Ma’mūn, where he studied the sciences and mathematics, which included the translation of Greek and Sanskrit scientific manuscripts. Some of his work was based on Persian and Babylonian astronomy, Indian numbers, and Greek mathematics. His writings include the text kitāb al-ḥisāb al-hindī (Book of Indian computation), and perhaps a more elementary text, kitab al-jam’ wa’l-tafriq al-ḥisāb al-hindī (Addition and subtraction in Indian arithmetic)
