However, the problem and its variants have appeared in the medieval mathematical literature of India, Europe and the Arab world.
[2] The name "Hundred Fowls Problem" is due to the Belgian historian Louis van Hee.
[3] However, no general method for solving such problems has been indicated, leading to a suspicion of whether the solutions have been obtained by trial and error.
[3] Some variants of the Hundred Fowls Problem have appeared in the mathematical literature of several cultures.
Here is a typical problem: Abu Kamil (850 - 930 CE) considered non-negative integer solutions of the following equations:
