Thus instead of , one would write + .

Studies from the 1970s to this day in Egyptian mathematics have clearly shown this theory was fallacious and Jim Ritter definitely showed it

Khasekhemwy went even further and placed both divine figures of Horus and Seth above his serekh, in an attempt to accentuate the dualism of a serekh name.
