Looks like the sum of cubes (multiplied by -1),
\n" ); document.write( " $\"1%5E3=1\"$
\n" ); document.write( " $\"2%5E3=2\"$
\n" ); document.write( " $\"3%5E3=8\"$
\n" ); document.write( " $\"4%5E3=64\"$
\n" ); document.write( " $\"5%5E3=125\"$
\n" ); document.write( " $\"6%5E3=216\"$
\n" ); document.write( " $\"7%5E3=343\"$
\n" ); document.write( " $\"8%5E3=512\"$
\n" ); document.write( " $\"9%5E3=729\"$
\n" ); document.write( " $\"10%5E3=1000\"$
\n" ); document.write( "So then,
\n" ); document.write( " $\"-S=1%2B2%2B8%2B64%2B125%2B216%2B343%2B512%2B729%2B1000\"$
\n" ); document.write( "Solve for S. \n" ); document.write( "

\n" );
