Eye of Horus fractions were written as the sum of two or more unit fractions (a fraction with 1 as the numerator), with scribes possessing tables of answers (see Rhind Mathematical Papyrus 2/n table). Thus instead of , one would write + . Different parts of the Eye of Horus were thought to be used by the ancient Egyptians to represent one divided by the first six powers of two: The Rhind Mathematical Papyrus contains tables of "Horus Eye Fractions". Studies from the 1970s to this day in Egyptian mathematics have clearly shown this theory was fallacious and Jim Ritter definitely showed it

Horus is recorded in Egyptian hieroglyphs as "ḥr.w" "Falcon"; the pronunciation has been reconstructed as . Additional meanings are thought to have been "the distant one" or "one who is above, over".
