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.)
