\n" ); document.write( "40 x 16
\n" ); document.write( "double the first and 1/2 the second
\n" ); document.write( "80 x 8
\n" ); document.write( "double the first and 1/2 the second
\n" ); document.write( "160 x 4
\n" ); document.write( "double the first and 1/2 the second
\n" ); document.write( "320 x 2
\n" ); document.write( "double the first and 1/2 the second
\n" ); document.write( "640 x 1 = 640.
\n" ); document.write( "--
\n" ); document.write( "If you meant something like (40)*(10+5+1)
\n" ); document.write( "then distribute the 40 to get
\n" ); document.write( "400 + 200 + 40
\n" ); document.write( "which equals 640. \n" ); document.write( "
