Here's how it works. This is the function described, but converted into math-ese: y = x-(x mod 10)-floor(x/10) Here is a graph of the function.This function returns the largest multiple of nine less than x. This is closely related to a helpful property of numbers divisible by nine in decimal - add the digits of a number, and if their sum is divisible by nine, so was the original number. When you subtract the modulus (in 54, that's the 4), you'll always wind up with a multiple of ten (50). Subtracting the tens place therefore must give you a multiple of nine because 10x-x = 9x. Now the key of the site, how it works. All of the multiples of nine have a cross. The problem with this is it looks painfully obvious if you just arrange the number in order, as you'll see a diagonal line of crosses. So they have to jumble the numbers to hide the pattern. Hope that was fun to read ;o
