Native American Mathematics

Eventually, the oldest of the three young braves decided that it was time to start a family, so he killed a deer, made a deer hide tent, and brought a bride home. Nine months later the couple had a healthy, joyous baby son.

A few months later, the second brave decided he needed to demonstrate his his adulthood. He went into the woods and brought back an elk hide, with which he made an elk skin tent to which he led his bride. In time, the couple had a healthy, active male child.

The youngest brave was geographically challenged: he did not even know what continent he lived on. He travelled far to acquire a hide for his bride. He eventually came home and made a wedding tent. His wife gave birth, nine months later, to twin boys.

This story goes to prove Pythagoras' Theorem:
'The squaw on the hippopotamus is equal to the sum of the squaws on the other two hides.'
