Answer 2

It is given that, Altitude above sea level =Positive Values

                                          =Positive Integer{1,2,3,4,5,6,7,8,.......}

Altitude below sea Level=Negative values

                                     =Negative Integer{-1,-2,-3,-4,-5,-6,.......}

Now, The situation given is

 A hiker in Death Valley stopping at an altitude of 0 feet

Zero(0)= The Point 0, means neither Positive nor Negative, that is additive Identity with respect to Addition of Integers.That is when two integers having Opposite sign, means additive Inverse of each other, are added together it yields Zero.

For example

-2 + 2=0

2 and -2 are Additive Inverse of each other.
