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 first row has been interpreted as the prime numbers between 10 and 20 (i.e., 19, 17, 13, and 11), while a second row appears to add and subtract 1 from 10 and 20 (i.e., 9, 19, 21, and 11); the third row contains amounts that might be halves and doubles, though these are inconsistent. [14]
The first true written positional numeral system is considered to be the Hindu–Arabic numeral system. This system was established by the 7th century in India, [1] but was not yet in its modern form because the use of the digit zero had not yet been widely accepted.

The first examples of the Greek system date back to the 6th century BC, written with the letters of the archaic Greek script used in Ionia.

Written in Cuneiform script, tablets were inscribed whilst the clay was moist, and baked hard in an oven or by the heat of the sun. Some of these appear to be graded homework. [22] The earliest evidence of written mathematics dates back to the ancient Sumerians, who built the earliest civilization in
For example, the number 88,888,888 would be written as M,ηωπη*ηωπη. [ 23 ] Milesian numeration, though far less convenient than modern numerals, was formed on a perfectly regular and scientific plan, [ 24 ] and could be used with tolerable effect as an instrument of calculation, to which purpose the Roman system was totally inapplicable.
