The first emoticon, :-\, means 'Undecided.' The second, ???, means 'Huh.' If Undecided = U00000000 + N0000000 + D000000, etcetera, then it is mathematically impossible for Undecided to equal Huh in the same base. However if Undecided = UxNxDxE...xD, then if N x D^3 X E^2 X C X I = H^2, this mathematical equation is correct.

Oh, and way to copy off of Wikipedia. Be more original.
