The lowest point in a particular country is negative 548−548 feet at a particular lake in a particular place. if you are standing at a point 660660 feet above the lake, what is your elevation?

The question is a bit ambiguous: when you want to compute the elevation of something, you have to define a zero-elevation point, so that you can compute the elevation of anything with respect to that zero-elevation point. Given the coordinate of the zero-elevation point, the altitude of every other point with coordinate is given by

So, assuming that the zero-elevation point is the bottom of the lake, and thus , your altitude at is

idk man good luck man
