Watch and be amazed at the inimitable (look it up, it’s a good word) constant from Indian mathematician D. R. Kaprekar. It’s a four-digit number that packs a punch! This video will cover how to get to it assuming you start with any other four digit number that has at least two distinct digits (e.g. 2222 is not allowed, but 2122 is). Buckle up, class!

Note: Subtract 1467 from 7641, not the other way around (though it's only a difference of a negative sign). Also, 4-3=1, not 4-1=1. Excuse me!
