My Wonky CalcuLESS (Posted on 2009-02-18) Difficulty: 3 of 5
I bought a new calculator at the Dollar Store and, sure enough, it’s defective. After some trial and error with it, I discovered that each digit in the display contained the same two pairs of elements (out of the seven elements labeled A to G below) that were somehow ‘cross-wired’. That is, if one element was called upon to illuminate, its partner would illuminate instead. If both were supposed to illuminate, neither would! For example, if A/D and B/F were the faulty pairs, the number 3 would simply display as F/G/C, as illustrated below.


Based on the illuminated elements for each digit given below, find the faulty pairs to then solve the following 3-digit by 2-digit multiplication:

ok; I never tried ABCF for 7 (only ABC); the only other alternative needed (which I had tried) was the ABCFG for 9 rather than ABCDFG.

Using those two alternatives, the program does find the solution you found.
