WebThe Egyptians produced tables of Egyptian fractions for unit fractions multiplied by two, the numbers that in modern notation would be written 2 n, such as the Rhind Mathematical Papyrus table; in these tables, most of these expansions use either two or three terms. [1] WebFeb 8, 2024 · Operations on fractions were reduced in Ancient Egypt to operations on aliquot fractions. More complicated fraction operations were decomposed with the aid of tables as the sums of aliquot fractions. In 1862 the first Egyptian text, the Berlin Papyrus, was published.
