The Rhind Papyrus: a scribe's handbook of problems
The Rhind Papyrus contains 84 mathematical problems. The date of the surviving roll may differ from the age of the problems it records.
What the Rhind Papyrus record says
The British Museum's object record for EA10057 describes the Rhind Mathematical Papyrus as a mathematics textbook containing 84 problems and gives a production date of 1550 BCE. British Museum ↗
A named scribe
The museum's second section, EA10058, names Ahmose as the scribe. Having a scribe's name attached to a copy is unusual, and it anchors the object firmly; it does not by itself tell us when the problems were first composed. British Museum ↗
Object date versus source tradition
The research record notes that the text may derive from earlier material, and it models the object date separately from any possible earlier composition. When a handbook copies older work, the copy's date and the tradition's age need their own evidence.
How old is the problem, not just the papyrus?
Pick one problem from the papyrus and ask what practical task it would serve. Then ask how you would know whether that method was new in 1550 BCE or already centuries old.
