Given these two sets of instructions, will you end up at the same place if you started at the same point? First instructions: 1) Take 5 steps forward 2) Turn around 3) Take 3 steps forward. Second instructions: 1) Turn left 2) Turn left 3) Take 6 steps forward 4) Turn around 4) Take 4 steps forward.
No, you will not end up at the same place. The first set of instructions ends two steps in front of the starting point, since you go forward 5 steps then backwards 3 steps. The second set of instructions ends up two steps behind the starting point, since you turn left twice, which is the same as turning around, and then go forward 6 and backwards 4.
