   1 dzień temu · The first part of the Rhind papyrus consists of reference tables and a collection of 21 arithmetic and 20 algebraic problems. The problems start out with simple fractional expressions, followed by completion (sekem) problems and more involved linear equations (aha problems).The first part of the papyrus is taken up by the 2/n table.The fractions 2/n for odd n ranging from 3 to 101 are ...
