The Concise Book of Calculation by Restoration and Balancing, commonly abbreviated Al-Jabr or Algebra, is an Arabic-language mathematical treatise on algebra written in Baghdad around 820 by Al-Khwarizmi. It was a landmark work in the history of mathematics, with its title being the ultimate etymology of the word "algebra" itself, later borrowed into Medieval Latin as algebrāica.
