>>The Royal Cubit was derived from the length of the King's outstretched arms.<<
I've heard about the stretching of the chord ceremony but not of any stretching of the arms ceremony. Was this measure redefined every time there was a new king? What happened to the old rulers were they burnt?

>>Further, they had no such thing as decimal fractions. The fractions they had were numeric: 1/2, 9/15, 3/22, 7/34.<<
You mean I have to use their type of numbering just to get the Egyptian feeling? This because a number is a number whether you write it as decimal or as a sum of fractions. Furthermore as I stated in my original post I do not take it as a given that the AE designed the pyramids.
