There is a 9x9 board. There is a bug on each and every square. At the sound of a signal every bug moves diagonally by one square. Some squares will end up with more than one bug, and some will be empty. What is the least possible amount of empty squares?

Zero. Nowhere does it say the bugs can't cross or are stuck to moving along a given diagonal. They can just switch over

Your math teacher must be retarded. Horribly worded question.

If they all keep moving diagonally, all the squares will be empty. If the bugs cycle back into empty squares on the opposite end of their exit, then there'll be no empty squares. Dafuq did I just post?
