Ancient African Mathematics: The Ishango Bone 26,000+ years old?

Retrieved 12 October Why are you making a hypothesis and not a proof? It has also been suggested that the scratches might have been to create a better grip on the handle or for some other non-mathematical reason. During earlier excavations at the Ishango site inanother bone was also found. They wondered if they could visit all the other numbers on their board, moving the counter using just these two operations: The location of Ishango.
