Draw the digits 1 to 7 in the smaller grid, and 0 to 9 in the larger grid, along the gridlines, so that they do not touch each other. The usual drawing of the digits must be distorted to fi t into the set of four triangles forming the skewed rectangle. Some of the possible drawings of “8” is shown. Digits can be rotated, but not refl ected. Numbers outside the grids show the sum of digits appearing in corresponding directions.
