maybe you have seen this before....
FORTY
+ TEN
+ TEN
-------
= SIXTY
If each letter represents a digit and all ten digits are to be included in the above equation. Can you find the arrangement of digits that would satisfy the equation?
(TEN does not mean T x E x N. It represents the places the digits take)

re: if you cant be bothered with equations by levik)
the O = 9 guess comes from the fact that there is
a carry number in 5th row. since O is only added
to the carry from row 3 it must be as big
as possible to be > 10. moreover, since I cannot
be 0, the carry from row 3 would never be big
enough if O werent 9
