Egyptian mathematics and Egyptian fractions

J. Sesiano

Abstract: Egyptian mathematics cannot be compare with contemporary Sumerian results. The problems solved as elementary, while multiplication and division do not exist as such: they are reduced to a succession of doubling and halving, Furthermore, fractions are not found, except for unit fractions, Therefore, a general fraction has to be expressed as a sum of unit fractions, This peculiarity gave rise at that time to tables of decomposition, and in modern times to the general question of expressing any fraction as a sum of unit fractions.
