Duodecimal System: Notation

In order to be able to represent numbers in the duodecimal system conveniently and readably, it is necessary to render the digits $10$ and $11$ using single characters.

The following techniques accomplish this:


$\mathrm T$ and $\mathrm E$
\(\ds 10\) \(:\) \(\ds \mathrm T\)
\(\ds 11\) \(:\) \(\ds \mathrm E\)

that is, the initial letters of ten and eleven.


$\mathrm A$ and $\mathrm B$
\(\ds 10\) \(:\) \(\ds \mathrm A\)
\(\ds 11\) \(:\) \(\ds \mathrm B\)

Hence this is consistent with the common form for hexadecimal notation.


$\mathrm X$ and $\mathrm E$
\(\ds 10\) \(:\) \(\ds \mathrm X\)
\(\ds 11\) \(:\) \(\ds \mathrm E\)

This was the suggestion from the Duodecimal Society in $1944$.
