Answer:
72 and -12
Step-by-step explanation:
An integer is a number that can be written without a fractional component. For example, 2 and -5 are integers, but 1.5 is not. Taking going up as an increment and going down as a decrement, then hiking 72 feet up a mountain could be represented by 72, and hiking 12 feet down by -12. In this way you can compute your new height as follows: new height = previous height + height variation. For example if you start at 200 m, then your new height will be: 200 + 72 = 274 feet, or 200 + (-12) = 188 feet
