Where does algebra derive from?

Answer 1

The word "algebra" derives from the work of Muhammad ibn Mūsā al-Khwārizmī, a Persian mathematician. In 830 he wrote a book entitled Kitāb al-muḫtaṣar fī ḥisāb al-ğabr wa-l-muqābala, in which he brought together various algebraic procedures the methods. The term "al-gabr" is believed to mean something like "restoration" or "completion" and refers to the translation of subtracted items to the other side of the equation.
