Question

a bird flies from the bottom of a canyon that is 81.8 feet below sea level to a nest that is 596 3/5 feet above sea level. what is the difference in elevation between the bottom of the canyon and the birds nest

Answer 1

Subtract.

596 3/5 - (-81.8)            [81.8 is below sea level so it is negative]
566.6 + 81.8                  [Convert to decimal and distribute negative]
= 678.4 feet
