RISE OVER RUN
(Rise) Using the farthest dot on the left you count how much you rise till you align with the second dot (depending on whether you go up or down determines + or -)
(Run) Once aligned with the second dot count whilst 'running' towards it till you've reached it. (If you go right it's +, if you go left it's -)
