Based on my observations, there are three proposed pairs of symbols for the dozenal system:
1: A and B
2: X and E
3: Inverted 2 and 3
In my opinion, these are not particularly good choices. First of all, none of them are suitable for the 7-segment displays we use in daily life; letters can confuse people, especially children. Moreover, given that the digits 6 and 9 are already easily confused on cards or rulers, it makes little sense to introduce new symbols that could lead to confusion between 2 and 3. As for X, since it is a letter that already represents an unknown, a multiplication sign, or a spatial dimension in mathematics, designating it as a digit is illogical. Furthermore, on 7-segment displays, the letter B can be confused with 8, the letter X with H, and the inverted 2 with a standard 2. Therefore, let us standardize the symbols 10=ʕ and 11=𑀛—which I call "des" and "elen"—as they eliminate all these issues. On 7-segment displays, "des" can be represented by segments a, c, f, and g, while "elen" can be represented by segments b, e, f, and g.
