xyz + zyx=686
\n" ); document.write( "In the correctly solved addition problem above, the letters X,Y, and Z
\n" ); document.write( " represent different nonzero digits. What is the value of x+y+z?
\n" ); document.write( ":
\n" ); document.write( "Perhaps we can reason this out, twice the middle digit is 8, y=4
\n" ); document.write( "Also x + z = 6
\n" ); document.write( "therefore: x + y + z = 10
\n" ); document.write( "
\n" );
