Answer 2

The answer is All of these.

As, 0 can't be written as -0 or +0 and non-negative means positive real number and non-positive means negative real number.

For ex.

-2+2
as the rules of integers say that '+' * '-' = '-'
and always greater number sign is there
So the answer is 0 .

Same in this case
+2-2
=0
