Question new symbol for negative integers

Circling the negative number signifies that the amount is Owed because the amount is not produced until it is paid. A class at Umass spoke about this that I was in, but we may have spoke oppressively so this is to be certain people have the discussion if it was an idea that people incorrectly said was not allowed. This is around 5 years after discussion.

I'm not sure I understand this symbolism. Is it representing a "hole" that must be filled with the number within? Or is the circle the "O" in "Owed"?

Also, "$-$" always seemed intuitive, at least to me, since you can think of $-a$ as just $0-a$. In the same vein as removing the $0$ from $1+0 = 1$.

A negative number isn't always an amount owed, in fact, it hardly ever is.

Since I can't easily circle a number in text, let's use curly brackets to illustrate a problem.
Where {5} is equivalent to -5:
what's 5{5}?
To remove ambiguity, you'd have to specify either:
5({5}) for a result of -25 or {25}
or
5+{5} for a result of 0 or {0}

Another issue is a technological one, how do you put a circle around a long number such as {1234567890}? A computer can manage it but you're going to need to update lots of software to account for it. This gets a bit trickier on a typewriter (I can think of a way to do it). Handwritten work could end up as an undecipherable mess (even more than mine already is!)

Furthermore

The significance is that because the negative number is not produced until it is actually paid the integer is circled, and yes the O means owed.

Parenthesis is a way to do it like you just did

There is no -2 until when the debt is paid, and it's more specific than using the symbol for minus

You are clearly not aware that there is no council that determines correct mathematical notation, and that all mathematical notation has been arrived at through usage and convention.

You can write negative numbers how you like, but you can't force others to like, use or understand your notation.

Why is this better than the usual minus sign? At best its completely equivalent with the minor disadvantage that nobody currently uses this and everyone is currently just fine with the normal minus sign. At worst, it seems like you might not completely understand the distinction between negative numbers and numbers with a minus sign in front of them.

Negative numbers don't generalize to amounts of (whatever) owed.

'Finance' tried another notation, red text to indicate negative numbers. Works until someone prints in black and white then faxes it....
But, it wouldn't be allowed now because it isn't politically correct to the colour-blind.
