Location Elevation(ft)
Mt. Driskill 535
New Orleans -8

The table shows the highest and lowest elevations in Louisiana. What is the difference between the elevations?
what is the difference between 6 and 10?

How did you find it?

Do the same step with the numbers above

recall how to subtract negative numbers:

10 - (-5) = 10+5 = 15
