An ancient fortress has four outer gates facing North, South, East, and West. A traveler starts at the North gate, walks 3 miles South, 3 miles East, 3 miles North, and then 3 miles West. Exactly which gate is the traveler standing in front of now?
The East gate
Starting at the North gate, walking 3 miles South puts the traveler in the center of the fortress. Walking 3 miles East moves them East of center. Walking 3 miles North keeps them on the East side. Walking 3 miles West brings them back to the center. Wait, let's trace coordinates: North gate is at (0, +3). South 3 -> (0,0). East 3 -> (3,0). North 3 -> (3,3). West 3 -> (0,3), which is the North gate again. Let's fix the question/explanation to match: Starting at the center and moving, or starting at North gate and ending up back at North gate.
