document.write( "Let \"n\" be the number of students.\r\n" );
document.write( "\r\n" );
document.write( "Then the number of \"wishes\"/letters is n*(n-1).\r\n" );

document.write( "\r\n" );
document.write( "3n*(n-1) = 2610,  or\r\n" );
document.write( "\r\n" );
document.write( "n*(n-1) = 870.\r\n" );
