Egyptians used a base 10 system with symbols for 10 multiples. Symbols allowed flexible reading directions. Hieratic symbols evolved for numbers 1-10.
Zero in Egypt had no numerical value but influenced numbers when added. It was also used in architecture.
Egyptians represented fractions, mainly with a numerator of one (1/x). Special hieroglyphs existed for 1/2, 2/3, and 3/4.
The Sacred Triangle of Egypt, with side lengths 3, 4, and 5 units, adhered to the Pythagorean Theorem and aided pyramid construction.
Formulas like c=2(a-b) and a=2c-b calculated the Sacred Triangle. Practical use included creating right angles for pyramids.
Notable pyramids, like Khafre, were constructed using Sacred Triangle principles with an inclination angle of 53° 07′ 48″.
