Answer: 5 to the right and 2 down (top right corner)
Start at the "birds" point. Moving 5 units to the right will get you directly above the "reptiles" point. Then move 2 units down to actually get to the "reptiles" point.
12-2+22/8 (=12.75 so the option of doing nothing isn't right)
12-(2+2)2/8 (=11 so that option is gone)
(12-2)+22/8 (=12.75 so that option is gone as well)
12-2+(22/8) (=12.75 So that's gone as well)
