The Dozenal Societies of America and Great Britain (organisations promoting the use of duodecimal) use turned digits in their published material: 2 (a turned 2) for ten (dek, pronounced dɛk) and 3 (a turned 3) for eleven (el, pronounced ɛl).

Dek and El are the transdecimal digits. They were orringinally when the Dozenalism started, they were debicted as: 𝛘 Ɛ They are sometimes currently depicted like this: ↊ ↋

Dek: Lost the ten border and is fully pink with pentagon eyes. El: Eyes are the same size, face moved upwards, and he's all pink except for the shoes. Do: Removed center border, she's fully white, has the same eyelashes from Six below her eyes, and her pants are red.

In dozenal, the number ten (also known as dek) may be written as "A", "X", "T" or a rotated "2" (introduced by Sir Isaac Pitman); the number eleven (also known as el, elv, lev, or ven) may be written as "B", "E", or a rotated "3" (also introduced by Sir Isaac Pitman).

Oct 8, 2017 · For El, you could enter unicode character U+0190. The character for dec looks less... correct. Not sure about that one. U/numerist may to have written papers using those …

Oct 8, 2019 · They pronounce the numbers 10, 11, and 12 in Base 12 as “dek,” “el,” and “doh.” Instead of placing a decimal after the units, such as in “13.25” in the decimal system, society members distinguish their numbers with a semicolon, such as “13;25.”

Oct 19, 2023 · Why Are There '24' Hours In A Day? The twelve symbols in the dozenal system are listed as 0-1-2-3-4-5-6-7-8-9-χ (pronounced ‘dek’) and ε (pronounced ‘el’). The number 10 in the system becomes 12 and is pronounced ‘doh’.

E = el (e) If the unit digit of the atomic number is 2, 3 or 9, then use “bium”, “trium” or “nonium” instead of “biium”, “triium” or “nonaium”. e.g. for tin ( Z = 42), you can call tin "quadbiium" (element symbol Db), and for gold ( Z = 67), you can call gold "sexseptium" (element symbol Sp)

Jan 18, 2015 · As mentioned in the comments, It works fine if you use a's and b's, but they tried to use names for "ten" and "eleven" which suggest their meaning. "dek" from "decem", coming from the latin word for 10, and "el" from "eleven", coming from the english word eleven.

Jun 16, 2016 · To fix this problem, ten is a rotated 2 (or X) and 11 is a reversed 3 (or E). Our counting would look like 1, 2, 3, 4, 5, 6, 7, 8, 9, X, E, 10. These last three numbers are pronounced “dek,” “el,” and “doh.” For example, if we wanted to pronounce 15 in duodecimal, we would say “doh-five.”
