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 $1+0 = 1$.

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!)

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

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. Thanks from topsquark

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.
