A coordinate grid has its x-axis pointing due East and its y-axis pointing due North.

A sluggish snail starts at point (0,0) and slowly slithers 1 unit North, 2 units East, 3 units South, 4 units West, 5 units North, 6 units East, 7 units South, 8 units West, 9 units North and (lastly!) 10 units East.

What are the coordinates of the snail's finishing point?
