    Compendio de cálculo por compleción y comparación
    Es un libro histórico de matemáticas escrito en árabe entre 813 y 833 d. C. por el matemático y astrónomo persa Al-Juarismi, perteneciente a la Casa de la sabiduría de Bagdad, capital del califato abasí en ese tiempo. En esta obra, Al-Juarismi expone los cimientos del álgebra, siendo el primero en estudiar sistemáticamente la resolución de ecuaciones de primer y segundo grado. La palabra álgebra se deriva de una de las operaciones básicas con ecuaciones (al-ğabr) descritas en este libro.
