The point that should be emphasized is the Ancient Egyptians were far more advanced then we have thus far been willing to give them credit. They, being intelligent beings knew written language translations are fraught with perpetual problems and chose the one language that cannot be corrupted and because two plus two will always equal four they chose the language of mathematics, the only logical choice to convey any message.
It is my personal opinion that instead of imposing our mathematical concepts, principles and elements on their structures we should make an effort to understand their methods and more than a few questions will be answered. Work we do requiring trigonometric calculations to accomplish the did with simple ratios. It is all a matter of understanding their methods.
I will give you an example of what I mean using the mathematics of geometry, the slope or incline the Grand Gallery is simply 360/(9^3) or 360/729 which gives our angle of 26º 16' 53.08" a figure within 13.08 arc seconds of Petrie's estimate.
The slope of the Ascending passageway is 360 / 1000 digits of the Royal Egyptian cubit 81/110*1000. 360 / 736 4/11 = 22/45 equals our angle of 26º 3' 12.58" within 43 arc seconds of Petrie's estimate.
Their methods really are too simple for our civilizations complex mathematical brains to understand, I believe that much the same might be said to the translations of the PT and other writings, we quite simply do not grasp the context.
