\n" ); document.write( "\n" ); document.write( "                    The posted statement is  INCORRECT.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "One possible counter-example is  m = 5,  n = 1.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It is true that  3  is not divisible by  m*n = 5*1 = 5,  in this case - - - so the premise is  TRUE.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "But the  \"then\"  statement is  FALSE: \r

\r\n" );
document.write( "    it is true that 3 is not divisible by 5, \r\n" );
