Tamika went hiking with her friends. the beginning of the elevation of -1. the highest elevation on the hiking path 100 feet. what is the difference in two elevations

They are different because the begainning elevation is -1 and we know that (-) meaning is something that decresed or going down, so let's say it's going down and the highest elevation is 100 feet (+) symbol meaning increased or going up let's say going up so the different is going up and down.
hopw it help you
