There are some areas of land on Earth that are below sea level. Imagine you are at the Dead Sea in Africa, which has an elevation of about −1,410 feet (1,410 feet below sea level). You then climb up 125 feet. What is your new elevation?

Answer 1

If you are at the Dead Sea, 1,410 feet below sea level, and you climb up 125 feet, your new elevation would be:

-1,410 feet + 125 feet = -1,285 feet

So, your new elevation would be -1,285 feet.
