This calculator displays a number in the form of ancient Egyptian hieroglyphs. The ancient Egyptian numeral system was used since around 3000 B.C.E. for three to four thousand years. The numeral system description can be found just below the calculator.
The ancient Egyptian numbering system 1
The ancient Egyptians developed the numbering system based on 10, no doubt because a human has ten fingers. They had the symbols to represent units, tens, hundreds, thousands, tens of thousands, and millions:
|10||hobble for cattle|
|100||coil of rope|
|1 000||lotus plant|
|100 000||tadpole (polliwog)|
|1 000 000||god Heh|
|Many millions (infinity)||lizard with three strokes|
The corresponding symbol is repeated to represent a number from 2 to 9, several tens, several hundred, etc.
The ancient Egyptians carved or painted most of their hieroglyphs from right to left, but sometimes the scribing order was reversed. Our calculator produces the numerical hieroglyphs sequence in reverse order with higher degree symbols on the left and lower degree ones on the right. You may recognize the reading order by the figures with face - start reading toward the front of its head.
The ancient Egyptians scribed a fractional number by a sum of unit fractions. For example, number 0.89 (89/100) can be expanded to the sum of unit fractions: 1/2+1/3+1/18+1/900. Read Egyptian fractions for more details.
A special symbol represented 1/2, and the other unit fraction denominators were scribed under the mouth symbol.
|1/2 - half|
|the mouth symbol was placed over a unit fraction denominator|
