HISTORY OF EGYPTIAN MATH
Numeration
Around 3000 B.C. Pharaohs began writing numerals for the first time. Egyptians carved their numerals in stone with a hammer and chisel. They also used the brush tip of a reed to paint them on shards of stone or hardened clay.
Egyptians used a decimal based system, a system with a base of ten. 1 is a vertical line or picture of a staff, 10 is a heel-bone sign, 100 is a coiled rope, 1,000 is a lotus blossom, 10,000 is a bent finger, 100,000 is a tadpole, 1,000,000 is a kneeling genie with raised arms. The numeral notation was brought up by the representation of standard objects or tokens (pebbles, shells, pellets, sticks, discs, rings, etc.).
Fractions
Fractions were mostly expressed by placing the open mouth symbol, representing the number one, over a giving number (n) to imply a fraction (1/n). There were special signs for some fractions like ½, ⅔, and ¾. Measures of volume were represented with the symbol of the painted eye of the falcon-god Horus (See image below). Each characteristic of Horus’s eye represents a fraction.
