-3 represents the distance from a stage to the floor below. 3 represents the distance from the stage to the top of a bookcase. What dose zero represent in this situation?

the distance from the floor below to the top of the bookcase

Step-by-step explanation:

From the question we are given the following

distance from a stage to the floor below = -3

distance from the stage to the top of a bookcase = 3

The distance from the floor below to the top of the bookcase = distance from a stage to the floor below + distance from the stage to the top of a bookcase

The distance from the floor below to the top of the bookcase = -3 + 3

The distance from the floor below to the top of the bookcase = 0

Hence zero represents the distance from the floor below to the top of the bookcase
