Can zero be represented by any number of tiles? Using only the unit tiles (only the
Two identical tiles in opposite regions will make zero.
There are other correct solutions.
In part (a), we reasoned that it is possible to make zero with
tiles. Since is a multiple of , we should also be able to make zero with . tiles
Could you add a single tile to part (a) and still have zero?
