Question 10970
 Positive integers are all the whole numbers greater than zero: 1, 2, 3, 4, 5, ...

Negative integers are all the opposites of these whole numbers: -1, -2, -3, -4, -5, … .

0 is neutral-- it's neither positive nor negative.

Let us take 0 as a starting point.
A win by 7 points mean 0+7 = +7
Similarly,a loss would mean 0-7 = -7

Elevation would mean 0+3400 = +3400 feet
Depression would mean 0-3400 = -3400 feet (By the way,in everyday terms we refer to this as __ feet above/below sea-level)
