\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So in this case, becomes and turns into \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So simplifies to which then becomes and finally simplifies to \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In the end, \n" ); document.write( "
