John lives on the side of a mountain and the elevation of his residence is 1025 feet above sea level. His brother lives in a deep valley that is 25 feet below sea level. What is the difference in altitude of the locations occupied by the two brothers?
Isn't it 1025-1050and that will give you 1050 feet difference. Since -1025 is sea level and -25 is which you will need to add will give you 1050 ft difference. I think that my math is correct
