Important Notes
- Draw a north arrow before solving and take East as positive x, West as negative x, North as positive y, and South as negative y. |
- Apply every turn from the person's current facing direction. A right turn changes direction clockwise; a left turn changes it anticlockwise. |
- Combine opposite movements before calculating distance: cancel East with West and North with South. |
- Decide the final direction from the signs of the remaining horizontal and vertical displacements. For example, positive x and negative y indicate South-East. |
