RE: Funny math problem to calculate the Pin Number for a credit card.
Here is the solution using a Casio fx-991EX.
I had to set the upper limit to .9999999999 (stored in Y) to avoid an error on this model.
At about \$18 USD, this is probably the least expensive physical calculator currently available new that can solve this problem.
