There are in total, 4 measure entries. Notice
that for each "+" there is a corresponding "-."
Because a measure of relative size is simply a
measure of difference, we could've ascertained
a priori that the change in size would sum to
0 by observing that as a rule, the sum of
all differences between all numerical
measurements always equals zero:
0 1 2 3
____________
0 | 0 1 2 3 |
| |
1 |-1 0 1 2 |
| |
2 |-2 -1 0 1 |
| |
3 |-3 -2 -1 0 |
