Only the tally marks for the numbers 1 and 5 are encoded, and tally marks for the numbers 2, 3 and 4 are intended to be composed from sequences of tally mark 1 at the font level. Counting Rod Numerals [1] [2]
Tally marks, Counting. Unary numbering is used as part of some data compression algorithms such as Golomb coding. It also forms the basis for the Peano axioms for formalizing arithmetic within mathematical logic. A form of unary notation called Church encoding is used to represent numbers within lambda calculus.
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.
In the Etruscan system, the symbol 1 was a single vertical mark, the symbol 10 was two perpendicularly crossed tally marks, and the symbol 100 was three crossed tally marks (similar in form to a modern asterisk *); while 5 (an inverted V shape) and 50 (an inverted V split by a single vertical mark) were perhaps derived from the lower halves of ...

The single tally stick was an elongated piece of bone, ivory, wood, or stone which is marked with a system of notches (see: Tally marks). The single tally stick serves predominantly mnemonic purposes. Related to the single tally concept are messenger sticks (used by, e.g., Inuit tribes), the knotted cords, khipus or quipus, as used by the Inca.
The use of tally marks in counting is an application of the unary numeral system. For example, using the tally mark | (𝍷), the number 3 is represented as |||. In East Asian cultures, the number 3 is represented as 三, a character drawn with three strokes. [6] (One and two are represented similarly.)
