There are four ways to go in a grid, right, left, up, and down. Right and up
are considered positive, left and down are considered negative.
We start at the origin (0,0).
If from the origin we go right and then up, say, +2 right and then +3 up, to the
point (2,3), we are in Quadrant 1. the ratio of 2 to 3 is the positive fraction
+2/3.
If from the origin we go left and then up, say, -2 left and then 3 up, to the
point (-2,3) we are in Quadrant 2. the ratio of -2 to 3 is the negative fraction
-2/3.
If from the origin we go left and then down, say, -2 left and then -3 down, to
the point (-2,-3), we are in Quadrant 3. the ratio of -2 to -3 is the positive
fraction +2/3.
If from the origin we go right and then down, say, +2 right and then -3 down, to
the point (+2,-3), we are in Quadrant 4. the ratio of +2 to -3 is the negative
fraction +2/3.
