Here are all of the possibilities: \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "13 = 1 + 2 + 10
\n" ); document.write( "13 = 1 + 3 + 9
\n" ); document.write( "13 = 1 + 4 + 8
\n" ); document.write( "13 = 1 + 5 + 7
\n" ); document.write( "13 = 2 + 3 + 8
\n" ); document.write( "13 = 2 + 4 + 7
\n" ); document.write( "13 = 2 + 5 + 6
\n" ); document.write( "13 = 3 + 4 + 6\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So there are 8 different ways to express 13 as a sum of 3 distinct positive integers.
\n" ); document.write( "
\n" );
