Here's the solution to the problem: Section C: Word Problems 25. A lift starts at floor 0. It goes down 6 floors, then up 9 floors, then down 4 floors. What floor is the lift now? Step 1: The lift starts at floor 0. Step 2: It goes down 6 floors, so the position becomes 0 - 6 = -6. Step 3: It then goes up 9 floors, so the position becomes -6 + 9 = 3. Step 4: Finally, it goes down 4 floors, so the position becomes 3 - 4 = -1. The calculation shown in your image is correct: -6 + 9 + (-4) = 3 + (-4) = -1 The lift is now at floor -1.
