What was one big flaw in the Egyptian number system?
Due to numeric length and character limitations, it was difficult to perform mathematical computations even as simple today as adding fractions in the Egyptian numeric system. To overcome this problem, ancient Egyptians would compose calculation tables to save time and lower the incidence of mathematical error.
How many symbols did the Egyptians have?
The Egyptians had a bases 10 system of hieroglyphs for numerals. By this we mean that they has separate symbols for one unit, one ten, one hundred, one thousand, one ten thousand, one hundred thousand, and one million. Here are the numeral hieroglyphs.

What is the Egyptian writing system?
The Egyptians had a writing system based on hieroglyphs from around 3000 BC. Hieroglyphs are little pictures representing words.

The way round this problem adopted by the ...

Fractions to the ancient Egyptians were limited to unit fractions (with the exception of the frequently used. ). A unit fraction is of the form. n n is an integer and these were represented in numeral hieroglyphs by placing the symbol representing a "mouth", which meant "part", above the number.
How many hieratic symbols are there in 9999?
The number 9999 had just 4 hieratic symbols instead of 36 hieroglyphs. One major difference between the hieratic numerals and our own number system was the hieratic numerals did not form a positional system so the particular numerals could be written in any order.
How many symbols are needed to make up the number 276?
Here are the numeral hieroglyphs. To make up the number 276, for example, fifteen symbols were required: two "hundred" symbols, seven "ten" symbols, and six "unit" symbols. The numbers appeared thus: 276 in hieroglyphs. Here is another example: 4622 in hieroglyphs.

A Short definition
Reliable Historians we know that in any ancient civilization mainly developed writing, and numeric values always stood in second place. For this reason, in mathematics of the past millennia many inaccuracies, and modern experts sometimes wrestle with such conundrums.
What were the signs?
To write the numerals the Egyptians used hieroglyphics, and they were not so much. Duplicating them according to a certain rule, it was possible to obtain a number of any size, however, this would require a large number of papyrus.
Transcript numbers
As a result of the above example, we see that in the first place we have designated 6 hundred, followed by two dozen and at the end of the two units. Similarly is written any other number which may be used thousands or tens of thousands.
Fractions are also important
The Egyptians earlier than most math. For this reason, in some point of mere numbers, they became a little, and gradually was introduced fractions. As the ancient Egyptian number system is considered of the hieroglyphic, to record the numerators and denominators were also used symbols.
Mathematical operation
If there are numbers, they add and subtract, multiply and divide. The Egyptian number system coped with this task perfectly, although there was a specificity. The easiest way produced the folding and subtraction. For this the characters of the two numbers recorded in the row between them was taken into account change of level.
Why formed the Egyptian number system?
The history of the characters, substitute the number, as vague as the appearance of the entire Egyptian civilization. Her birth dates from the second half of the third Millennium BC. It is generally believed that similar accuracy in those days was a necessary measure. Egypt was already a full-fledged state and each year became stronger and larger.
Egyptian number system: advantages and disadvantages
The Main achievement of the ancient Egyptians in mathematics – simplicity and accuracy. Looking at the character, it was always possible to determine how many tens, hundreds or thousands written on papyrus. Dignity was also considered as a system of addition and multiplication of numbers.

Egyptian Numbers. The system of Ancient Egyptian numerals was used in Ancient Egypt until the early first millennium AD. Egyptian Numbers and calculations were important to the Egyptians especially in the construction of Pyramids and monuments.
What did the Egyptians know about addition?
Egyptians knew addition, subtraction, some division and multiplication. They only multiplied and divided by two, so if they wanted to find ex 5, they would use ex 2 + ex 2 + e. 13 / 4 was done as 4 x 2 + 4 = 12, 13 – 12 = 1, and so the answer was 3 ¼.

What fractions did the Egyptians use?
The Egyptians almost exclusively used fractions of the form 1/n. One notable exception is the fraction 2/3 which is frequently found in the mathematical texts. Very rarely a special glyph was used to denote 3/4. The fraction 1/2 was represented by a glyph that may have depicted a piece of linen folded in two.
When was the first papyrus discovered?
There are two major sources: the Moscow Papyrus - which dates to ca. 1800 BCE - and the Rhind or Ahmes papyrus - which dates to ca 1900 BCE, but is likely a copy from an original dating to ca 1800 BCE. These papyri are discussed in more detail in The Mathematical Papyri.
What technique did the Egyptians use to compute their products?
The Egyptians used a technique called "repeated doubling" to compute their products. The technique is most easily explained through an example. Suppose we wish to compute 11 X 15. We first find several easy multiples of 15:
