For the sake of convenience, I'll say the Earth's circumference is 1 unit.
You leave your house, turn to face east, then travel 1/6 unit in a straight line, you check your
compass to make sure you are going east, then travel 1/6 unit in a straight line, and so on,
travelling along 6 straight lines in total. You are now at exactly 1°N, 1°E. Where did you
start?
