Mount Everest is above sea level and the deepest point of the Java trench in the Indian ocean is below sea level. What is the difference of level between the two places?
Calculate the difference of level between the two places
The height of Mount Everest is (Since it is above the sea level)
The depth of Java Trench is (Since it is below the sea level)
The difference between the two places
Thus, the difference between the two places is
