This really has nothing detecting but moreso with numbers and at my job that is a major part of what I do....CRANK NUMBERS. Anyway, here's one that I think y'all could appreciate since not many know this: Take and multiply the below numbers and see what you get: INTERESTING!
111,111,111 x 111,111,111 = 12,345,678,987,654,321

111,111,111 x 111,111,111 = 12,345,678,987,654,321
