    Post subtraction of zero

    IS THIS A NUMBER THEORY?
    IS IT ALREADY KNOWN?
    0 = 0 : (IS this the first known enumeration?) : +0 = 0 = +0
    0 = +0 : ARE unsigned numbers are always positive ?
    +0 - +0 = +0 = 0 : subtraction of same
    +0 + -0 = 0 : sign exchange (needs new enumeration) : -0 = 1 = +1
    then -0 = 1 and -0 = +1
    then +0 = 0 and +0 = -1
    +1 - +1 = +0 = 0
    +1 + -1 = 0 : sign exchange (needs new enumeration) : -1 = 2 = +2
    then +1 = 1 and +1 = -0
    then -1 = 2 and -1 = 2 = +2
    does (subtraction of zero) lead to the real integers number system?
    is it something left undefineable?
    it seems that the negative number is always one less than the new enumeration ... -n = abs(-n)+1

    If you are distinguishing 0, +0, and -0 as separate numbers, then you should not set 0 = +0. Rather +0 is another positive number in this case, and -0 is its negative.

    You are then free to use the notation 1 instead of +0 (as long as you only do addition, no multiplication).

    Question zero equals positive zero

    it seems to me 0, +0 and -0 are not three different numbers, that they are two different numbers.
    0=(0 = +0) 1=(-0 = -0)=(1 = +1)
    0 and +0 are the same number, aren't unsigned numbers are always positive?
    -0 seems to be the problem
    can one exchange signs in this way to produce -0? and can -0 even exist?
    if true, do you think this would contribute to future mathematical studies?

    If 0 =+0, then 0 = (+0) + (-0) = 0 + (-0) = -0, therefore also 0 = -0 = +0.

    No, it's nothing new.
