A direct successor in the development of algebra to al-Khwarizmi, his texts on algebraic theory helped to form the groundwork for later mathematicians, including al-Karaji. Fibonacci would later adopt his mathematical techniques.
Abu Kamil worked to perfect many of al Khwarizmi s algebraic methods including work with the multiplication and division of algebraic objects and the addition ...
