The system of ancient Egyptian numerals was used in Ancient Egypt from around 3000 BC [1] until the early first millennium AD. It was a system of numeration based on multiples of ten, often rounded off to the higher power, written in hieroglyphs. The Egyptians had no concept of a positional notation such as the decimal system. [2]
[29] [30] [31] A decimal version of the sexagesimal number system, today called Assyro-Babylonian Common, developed in the second millennium BCE, reflecting the increased influence of Semitic peoples like the Akkadians and Eblaites; while today it is less well known than its sexagesimal counterpart, it would eventually become the dominant ...
Ancient Egyptian mathematics is the mathematics that was developed and used in Ancient Egypt c. 3000 to c. 300 BCE, from the Old Kingdom of Egypt until roughly the beginning of Hellenistic Egypt. The ancient Egyptians utilized a numeral system for counting and solving written mathematical problems, often involving multiplication and fractions .
c. 20,000 BC — Nile Valley, Ishango Bone: suggested, though disputed, as the earliest reference to prime numbers as also a common number. [1] c. 3400 BC — the Sumerians invent the first so-known numeral system, [dubious – discuss] and a system of weights and measures.

The audience for this book, according to reviewer Kevin Davis, is "mid-way between a specialised and a general readership". [8] Alex Criddle echoes this opinion, suggesting that "those without a special interest in mathematics may find it very dry and hard to understand" but that it should be read by "anyone interested in the history of mathematics, egyptology, or Egyptian culture".
