There are two collections of problems in al-Khwārizmī’s Algebra. The first is part of what I call the “algebra proper”, and consists of the thirty-nine worked out arithmetic problems in the first half of the book. This set of problems is the object of my study. It is not to be confused with the collection of inheritance problems that make up the second half of the book, after the chapters on business arithmetic and mensuration.
I have written much more than I expected, so I will summarize my arguments here and give links to my longer study and to my translation of the whole corpus. First, the links:
“The series of problems in al-Khwārizmī’s Algebra”. 13 pages, plus bibliography. here
