 ## Ancient Egyptian Numbers

### Ancient Egyptian Number system

Similarly, the Egyptians did not follow a numbering system like ours, where there are 9 digits 0 to 9 and larger numbers are formed with these figures. They had the system unary numbers, agreement between the ancient civilizations. In this system, a single line means one, two lines means two or three rows of three and so on. When he reached 10, a new symbol of an inverted U was used. A coil of rope was a symbol of a hundred.

The symbol of a thousand is the lotus or water lily. It shows the leaf, stem and rhizome or root. One great human finger symbolized the number ten thousand. The number one lakh was represented by a tadpole to turn around a frog. Heh god or a man with both hands raised was the symbol for a million, sometimes used as infinity.

A symbol that looks like a circle was again used to represent infinity, because a journey through an endless circle. Multiples of these values ​​were expressed by repeating the symbol as many times as necessary. As they had no concept of zero, there was no symbol for it.

The system of ancient Egyptian figures was used in ancient Egypt until the early first millennium AD. The figures and calculations are important for the Egyptians in particular in the construction of pyramids and monuments. They wanted to calculate the amount of work, the number of blocks of stone, the amount of food for workers mathematics etc.

was also important in measuring time, straight lines, the level of the Nile flood, the areas of computing of land, counting money, working on taxes and the kitchen. Egyptians knew addition, subtraction, division and multiplication certain. They multiplied and divided by two, so if they wanted to find ex-5, they used ex 2 + ex 2 + e. 13/4 was carried out in 4 x 2 + 4 = 12, 13 - 12 = 1, so the answer was 3 ¼.

Be able to multiply and divide by two Egyptian mathematics was difficult to handle. For integers as 32, the Egyptians would write: 10 + 10 + 10 + 1 + 1. Although simple, the way the Egyptians wrote their math is long and repetitive. "GS" The Egyptian sign was used for "side" or the word "half" ½. "Hsb the word meant" fraction ". represented and plus and minus signs, respectively. The Egyptians were somewhat familiar with the roots and square roots.

The Great Pyramid of Khufu of the Fourth Dynasty was a mathematical miracle, as it was laid out with geometric precision. The Egyptians also made the 365-day calendar, which once again proves their excellence in math skills. Although the Egyptian number system was difficult, it must be accepted that they were one of the ancient civilizations that created wonders with numbers.
