Book of Birds

Subject Matter

  • Systematic procedures for finding integral solutions for indeterminate equations


Historical Note

Possibly the first work that investigates the number of solutions to a general indeterminate equation.

The title is derived from a type of problems known in the east: the One Hundred Fowls problems, which involve the purchase of different species of birds.

The book arose as an offshoot of his Kitāb al-ṭarā'if fi'l-ḥisāb.
