I was told of Algebra coming from Al-Jabr meaning "number games". I was surprised I didn't see this mentioned in the article, until I found the book mentioned in Al-Khwarizmi's biography [1]. The book's title is "Hisab al-jabr w'al-muqabala" but no translation is given and Google's translation "Al Jaber account and interview" is not helpful. Can anyone confirm or deny the explanation I was given?
