\n" ); document.write( "Can't be done!
\n" ); document.write( "Sum 1 to 9 is 45.
\n" ); document.write( "The sum of all the digits of the 1st two 3 digit numbers + possible carry=
\n" ); document.write( "sum of 3 \"answer\" digits.
\n" ); document.write( "If there is no carry, these 2 \"equal\" sums add to an even number, not 45.
\n" ); document.write( "So there must be a carry.
\n" ); document.write( "And the \"answer\" digits must sum to 23.
\n" ); document.write( "Only way is 9 8 6 and to get a carry, 9 would have to be on top too.
\n" ); document.write( "
