No you don’t. In a positional base system we use, we need it. Where 10 is larger than 1, which the 0 denotes.
 
But there are other number system, like bijective. In bijective base 9, you have the 9 digits from 1 to 9 (values 1 to 9). After 9 comes 11 (value 10), 12 (value 11), to 19 (value 18), then 21 (value 19), up to 99 (value 90), then 111 (value 91). A 0 is never used.
 
You also got the Roman system: I, II, III, IV, V, VI … IX X XI (9, 10, 11) … CMXCIX, M, MI (999, 1000, 1001). A 0 is never used here either.
 
To express zero of something, you can say that there’s none of it, or there’s nothing.

@Surprise22  
But you need a symbol to represent 0 in any numerical system. I mean we have one, and I just used it in the last sentence

This is relatively simple. But interesting

You could probably argue that Pegasi generally have five primary feathers on each wing, and they’re responsible for base 10 numbering.
 
I might be pulling stuff right out of my ass but who cares.

no wait you got it right

0 is a null number so start with 123456789abcdef

hexadecimal is base 16

@Liggliluff  
I’ve decided to leave it as is. People who intend to use the font can choose which base they prefer. 2, 4, 6, 8, 10, 12, or 16.

@Fonypan  
Maybe 8 could work better?

@ChrisEggII
 
I originally had a base of 4, but then decided it was to small, and so with the magic of multiplication I decided to go with a base of 16.

I like this idea. But I have one question… Why did you choose hexadecimal?

Base-16, or hexadecimal doesn’t go to 0-15. I have an example of what a base-16 may look like.  

 
(Instead of the inverted 2-7, you can also use A-F.)

It’s just a substitution cypher.  
Bah! ;-;  
:p

The pony language in the show has more than only horseshoes… such as wings, heads and more.
 
However… simply replacing an English letter into each symbol doesn’t make it a unique language.
 
Having unique letters and a unique language such as the Klingon language would be more interesting.

@Background Pony #F60F  
Hexadecimal… using computers; base 16 is pretty normal.

While the idea of it being based on fours has some sense, at the same time I’m not sure if they would actually do that - basing things on tens seems a lot more convenient. And the sixteen things is like completely out of nowhere. Besides, don’t they already use normal numbers in the show?
 
Anyway, I think it’s best to just do it normally and stick to 0-9.

Poneiform?

Neat concept.

@CaptainCactus  
Same way humans type out a number larger than nine. Use more than one digit.

@CaptainCactus  
Uh, maybe by having them repeat until say ninety or so and then using another number for that? I dunno, but ti seems interesting.

Fantastic! Only one (probably obvious) question, how would you type out a number higher then 15?
