    I'm kind of confused by your question, but:
    2 exists and it's positive (2=+2)
    and if x=1 then -1+x+1=1
    and -1x1=-1

    I don't quite understand your question.
    What would be the use of having a number "between"?

    What would these be?

    [tex](-1) + (-1)=~?[/tex]
    [tex](1) + (1)=~?[/tex]
    [tex](+1) + (+1)=~?[/tex]

    A value between -2 and 2 would be 0.
