A clever mosquito is sitting on a rular with positive as well as negative marks. Its initial position is the mark of
on the rular. Just for fun it flies then to mark
and from there to mark
and from there to mark
and so on till it reaches
. What is the magnitude of the total displacement of the mosquito?
The answer is 11.
