Subtracting Integers - sea level difference
From the book: "If the elevation of Lake Superior is 600 feet above sea level and the elevation of the Caspian Sea is 92 feet below sea level, find the difference of the elevations."
My answer: 600 - (-92) = 600 + 92 = 692 ft
Am I correct? This seems very obvious to me, but I'm just double checking.
I realize that this is really late.
I would like to point out why in algebra you say
it is because in moderately low to highly advanced math you are NOT allowed to use logic, only formulas. Therefore, I would say the formula for solving this problem is and then I would substitute the values into this equation
Another reason: when you start to get into bigger equations, you will have to use the cumulative property of addition and other properties...
