Replace each of the letters by a different number from 0 to 9 to satisfy the following alphanumeric equation:

(PIN)*(PIN) = BUNDLE

Note: Neither P nor B can be 0.

The first thing I did is look for for a few three digit numbers that would be valid as PIN and had a product where the third digit from the right was equal N. I soon realized that N could not be 0,1,5 or 6 because the last digit in the product (E) can not be equal to N. Unfortunately, I couldn't discover any other exclusions, so I used the brute force method.....


324 X 324 = 104976
