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 name King Sekhemib, "Per-en-ma'at" (meaning "he who achieves Ma'at"), is the clearest early expression of this. As already mentioned, most Egyptian kings favored Horus as their dynastic name patron.
