Tally marks, also called hash marks, are a form of numeral used for counting. They can be thought of as a unary numeral system. They are most useful in counting or tallying ongoing results, such as the score in a game or sport, as no intermediate results need to be erased or discarded. However, because of the length of large numbers, tallies ...
Numeral systems. 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.

The number of tally marks required in the unary numeral system for describing the weight would have been w. In the positional system, the number of digits required to describe it is only k + 1 = log b w + 1 {\displaystyle k+1=\log _{b}w+1} , for k ≥ 0.
sanchū. Counting rods (筭) are small bars, typically 3–14 cm (1" to 6") long, that were used by mathematicians for calculation in ancient East Asia. They are placed either horizontally or vertically to represent any integer or rational number. The written forms based on them are called rod numerals.
The history of the alphabet goes back to the consonantal writing system used to write Semitic languages in the Levant during the 2nd millennium BCE. Nearly all alphabetic scripts used throughout the world today ultimately go back to this Semitic script. [1] Its first origins can be traced back to a Proto-Sinaitic script developed in Ancient ...
