The Roman numerals, in particular, are directly derived from the Etruscan number symbols: π , π‘ , π’ , π£ , and π for 1, 5, 10, 50, and 100 (they had more symbols for larger numbers, but it is unknown which symbol represents which number).

Roman numerals, the Brahmi and Chinese numerals for one through three (δΈ δΊ δΈ), and rod numerals were derived from tally marks, as possibly was the ogham script. [7] Base 1 arithmetic notation system is a unary positional system similar to tally marks. It is rarely used as a practical base for counting due to its difficult readability.
A return to an open palm signals the number 10. However to indicate numerals to others, the hand is used in the same manner as an English speaker. The index finger becomes number 1; the thumb now represents number 5. For numbers above five, the appropriate number of fingers from the other hand are placed against the palm.
Number systems have progressed from the use of fingers and tally marks, perhaps more than 40,000 years ago, to the use of sets of glyphs able to represent any conceivable number efficiently. The earliest known unambiguous notations for numbers emerged in Mesopotamia about 5000 or 6000 years ago.
This is the minimum number of characters needed to encode a 32 bit number into 5 printable characters in a process similar to MIME-64 encoding, since 85 5 is only slightly bigger than 2 32. Such method is 6.7% more efficient than MIME-64 which encodes a 24 bit number into 4 printable characters. 89
Ancient Aramaic alphabets had enough letters to reach up to 9000. In mathematical and astronomical manuscripts, other methods were used to represent larger numbers. Roman numerals and Attic numerals, both of which were also alphabetic numeral systems, became more concise over time, but required their users to be familiar with many more signs.

In modern scores, the fingers are numbered from 1 to 5 on each hand: the thumb is 1, the index finger is 2, the middle finger is 3, the ring finger is 4 and the little finger is 5.
