图解：在图中任选一个方格，记住它的序列数。以该方格为起点“1”，沿斜线方向，向下（向左侧及右侧均可）数方格，一直数到最下面的序列（序列的最大数）中的方格为计算结果。如图：图中代表性的选了4个方格为起点（第1序列上选了两个方格；中间第5序列选了一个方格；下方第11序列选了一个方格），沿斜线（箭头方向）向下数方格数：用不同颜色的斜线标明数方格的方向及计算结果。

结论：

R=V-(A-1)

R与H无相关性

该结论也适用于四边形

Illustration: Choose any square in the diagram and memorize its sequence number. The square as a starting point "1", move along the diagonal direction, counting the number of squares downwards (left and right are also acceptable directions) until reaching the bottom square with the highest sequence number. As illustrated: select four squares as starting points (the first sequence selects two squares; the fifth sequence selects one square in the middle; the 11th sequence selects one square below), moving along the diagonal (following the direction of the arrow) and counting the number of squares. Different colored diagonal lines indicate the direction of calculation and results based on the number of squares.

Conclusion: 

R=V-(A-1)

R is not relevant with H.

This conclusion also applies to quadrilaterals.
