The Egyptians wrote on papyrus scrolls and the Babylonians wrote on clay tablets. The Egyptians wrote many math problems on one scroll, and the Babylonians solved only a single problem on one clay tablet.
The Egyptian Rhind Papyrus contains material from about 1800 BCE. It measures 18 feet long and one foot wide. Eighty-four problems are solved on the Rhind Papyrus. I remarked that they must have pressed the papyrus leaves together to form paper, to be able to get a scroll that's 18 feet long. I was amazed. Austin remarked, "What else would you expect, Mom? These are the Egyptians we're talking about. Can you explain the pyramids?"
