Answer:

3 floors :)

Step-by-step explanation:

we have been given that an elevator goes up 7 floors

we know that going up is a positive altitude, so 7 floors up will be positive 7

then the elevator comes down 4 floors. We know that coming down is a negative altitude, so coming down 4 floors would be  floors

the change in the floor would be floors

therefore, the change in the floor level is 3 floors

hope it helps<3

+3

The elevator went up 7 floors, making the current integer +7. The elevator then went down 4 floors, so 7 - 4 is 3. The final answer representing the change in floor level is +3 (positive three.)
