Mount Everest is 29,028 feet
above sea level. The bottom of
the Mariana Trench is 36,070 feet
below sea level. What is the
difference between these two


  1. Subtracting these elevations, their difference is 65,130 feet.

    How to find the difference between these two elevations?

    We find the difference subtracting these two elevations. They are given as follows:
    • Mount Everest: 29,028 feet above sea level, hence + 29,028.
    • Mariana Trench: 36,070 feet below sea level, hence – 36,070.
    The difference is given by:
    29,028 – (-36,070).
    Subtracting a negative number is the same as adding the positive number, hence:
    29,028 – (-36,070) = 29,060 + 36,070 = 65,130.
    The difference of these elevations is of 65,130 feet.
