Take any number
\n" ); document.write( "\"z\"
\n" ); document.write( "Square that number and then subtract one.
\n" ); document.write( "\"z%5E2-1\"
\n" ); document.write( "Divide by one less than your original number.
\n" ); document.write( "\"%28z%5E2-1%29%2F%28z-1%29\"
\n" ); document.write( "Now subtract your original number.
\n" ); document.write( "\"%28z%5E2-1%29%2F%28z-1%29-z\"
\n" ); document.write( "We can factor \"z%5E2-1\"
\n" ); document.write( "\"z%5E2-1=%28z-1%29%28z%2B1%29\"
\n" ); document.write( "\"%28z%5E2-1%29%2F%28z-1%29-z\"
\n" ); document.write( "\"%28%28z-1%29%28z%2B1%29%29%2F%28z-1%29-z\"
\n" ); document.write( "\"%28cross%28%28z-1%29%29%28z%2B1%29%29%2Fcross%28%28z-1%29%29-z\"
\n" ); document.write( "\"%28cross%28z%29%2B1%29-cross%28z%29\"
\n" ); document.write( "\"1\"
\n" ); document.write( "That's how this game worked.
\n" ); document.write( "I leave it to you to come up with your own.
\n" ); document.write( "Working backwards is usually the best way to get the answer.
\n" ); document.write( "
\n" );
