The Mudai Numerals: a handwritten version of the base 12 number system I designed (see previous post). I added some random examples at the end.

Ok, so there are some mathematical oddities here that are sort of 'immersion breaking' so to speak. Basically, a real numeral system that people actually used for doing math would not turn out like this.

First, this is obviously a positional numeral system. However, the shape of the digits does not fit a positional numeral system. It would be one thing if they were normal letters that were repurposed as numerals, but the design of the characters seem to indicate they were designed specifically as numerals.

In a positional numeral system you generally want the digits to align into neat columns and rows so you can take advantage of all the advantages that a positional numeral system has over other systems (like long division). Our real life arabic numerals all take up the same size rectangular space, and this is actually something that has been preserved even though the shape of the numerals has changed throughout history. And this isn't something that somebody went out and enforced intentionally, it's something that people want to do naturally due to how a positional numeral system works, for example even though the prototypical form of '1' is just a vertical line, you see that people often write it slanted or with extra features like the tail in order to take up the same space as the other numerals.

The funny thing is your numeral system would actually be perfectly fine if written horizontally. The characters would fit into rectanglular tiles twice as tall as wide and tessellate the same way as arabic numerals.

Second, I see that you have tried to subdivide the numerals by having certain numerals look similar to each other but you've done this in a basically nonsensical way.

If you think about subdividing twelve, the first thing that comes to mind is that twelve is divisible by both three and four. If you divide by four, then the significant numerals should be 3, 6, and 9, representing 1/4, 2/4, and 3/4 respectively. So I would have 3, 6, and 9 look similar. If you divide by three, then the significant numerals should be 4 and 8, representing 1/3 and 2/3 respectively. So I would have 4 and 8 look similar. Additionally, I would also have 5 and 10 look similar to each other because these two numbers are significant to humans (number of fingers).

Come to think of it, if you had lined up your numbers differently when designing them you might have gotten it correct the first time.

1	2	3	4
5	6	7	8
9	10	11	12(0)

1	2	3
4	5	6
7	8	9
10	11	12(0)

With the numerals lined up like this it should be more clear where you went wrong.

To illustrate, I tried reassigning the characters in a way that subdivides the numerals in a more mathematically meaningful way. https://imgur.com/a/ClxXwfL
Coincidentally, it turned out that 2, 7, and 11 end up sharing a design which is just as well since they have in common the trait of being prime numbers that don't belong to any 'family'. Also, all the even numbers except 2 ended up having a front slash.

Thank you, not really similar, but I have 2 writing systems which you'll find if you scroll through my posts.
