The Compendious Book on Calculation by Completion and Balancing was a treatise written by Muhammed ibn Musa al-Khwarizmi during his time in the House of Wisdom. It was published around 830.[1]

Content Edit

In the book, al-Khwarizmi explained the process of balancing both sides of an equation, and gave a systematic way of solving quadratic equations, which had been described almost 500 years earlier by Greek mathematician Diophantus of Alexandria. Central to his method was the principle of balancing an equation by transposing terms from one side to the other and canceling out terms that appear on both sides.[1]
