Because people need to see to understand.

For those familiar with the original manual.

Format How to interpret
n [w×h] 9 3×3 15 5×3 21 7×3 25 5×5 35 7×5 49 7×7
(n) [w×h] 9 3×3 15 3×5 21 3×7 25 5×5 35 5×7 49 7×7
w×h w is the width, h the height of the grid.
h by w h is the height, w the width of the grid.
n*h n is the total size of the grid, w = n / h.
n : w n is the total size of the grid, h = n / w.
