I have a question on math if I start to look for a object hidden by making the center of a field as (0,0), with coordinates giving distances in yards. Coordinates to the north or east are positive and coordinates to the south or west are negative. And I find nothing at (12,8), so I try a likelylooking spot 3 yards to the east and 11 yards to the south of the first spot. Can you explain what are the coordinates of the second spot?
Is it (9,19) ?

Reiny,
Your first coordinate is correct as 9
for the 2nd, you are at 8 and are going south for 11
so 811 = 3
your new point is (9,3)
