A Calculated Display


Susan Thorpe


The numbers which appear on the LCD of a calculator are made of a series of straight-line segments. For the purpose of the current exercise, I ignored (a) the gap junctions between the straight-line segments and (b) the fact that the numbers are displayed at an angle. The game is to turn the ten numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 on the calculator display into words. To do this, I started with a three-by-five grid of 15 cells, the smallest possible grid for the exercise. When drawn on the grid, each number occupies specific cells. Among them, the ten numbers use 13 of the 15 cells, indicated by Os in Figure 1. The two interactive cells have a cross (X).
