Answer:
a. -3
b. 0
Step-by-step explanation:
Going 1 floor up would mean Starting Floor+ 1=-2
Here we move the 1 over by subtracting 1 on each side
Starting Floor = -3. So for a our starting Floor was -3
Going five floors down would mean -5 floors and then 3 floors up would mean +3. So -5+3 is -2. In total you went down 2 floors. In order to go from -2 floor to -2 floor it would mean you starting from floor 0 and 0-2 is -2 floors.
