why did we not consider the area b/n 0 to -1?
I know it would not make a difference in the answer but still

I'm not quite sure which statement you're referring to - but for either one, this region doesn't work. If b is between 0 and -1, and it is rounded to the nearest tenth, the result will not be 0.5. And if we rounded to the nearest integer, the result would not be 1.

For example, imagine we had -0.34. The result of rounding to the nearest 10th would be -0.3. And the result of rounding to nearest integer would be 0.
