Count $\"+1+\"$ for the 1st corner where you start.
\n" ); document.write( "Count $\"+21%2F3+=+7+\"$ to get to the next corner
\n" ); document.write( "Count $\"+7+\"$ to get to the 3rd corner
\n" ); document.write( "Count $\"+7+\"$ to get to the 4th corner
\n" ); document.write( "The 5th corner is where you started,
\n" ); document.write( "so only count $\"+6+\"$ to finish
\n" ); document.write( " $\"+1+%2B+7+%2B+7+%2B+7+%2B+6+=+28+\"$
\n" ); document.write( "There are 28 posts \n" ); document.write( "

\n" );
