# How Unicode can save math: part 2

It’s widely known that decimal – or “numbers” to most of us – is an inferior system. Decimal doesn’t work well for computers, which prefer base two and it doesn’t work well for humans either, at least not when compared to dozenal.

Dozenal is also called “duodecimal,” or “base 10” (when writing in dozenal) and it is a much more natural system for humans than decimal. The usual example of why is a clock. Look how neat it is with the number 10 right at the top:

Dozenal has a big problem though, as we can see from the clock. What number does 10 represent, when you see it out of context? You just don’t know.

For decades, we’ve solved this problem in computer programming with funny prefixes. To a programmer, dozenal and decimal might be “base 0xA” and “base 0xC”. Likewise, in a dozenal world, we might write “hexadecimal” as “base 0z14” or something. If we need to start writing all our numbers with warts to indicate the base, however, dozenal seems doomed.

But wait, there’s hope. Unicode already contains the digits for “dek” and “el.” (That’s ten and eleven, if you’re not a cool dozenal kid.) If your browser doesn’t have a suitable font, refer to the clock above. If it does, they look like this:

↊ ↋

Now all we need is nine more Unicode symbols for the rest of the digits. Zero is special: for zero, there need be only one.
