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?

$$(-1) + (-1)=~?$$
$$(1) + (1)=~?$$
$$(+1) + (+1)=~?$$

A value between -2 and 2 would be 0.
