How to Play
📝 How to Play:
- Look at Point A (blue) and its coordinates (X, Y)
- Find Point B (purple) on the grid
- Calculate Point B's coordinates
- Remember: Right = +X, Up = +Y, Left = -X, Down = -Y
💡 X,Y Coordinate System
Every point on a grid has two numbers: X (horizontal) and Y (vertical). The ISS uses coordinates to track its position on Earth!
