\r\n" );
document.write( "1. Get a calculator.\r\n" );
document.write( "\r\n" );
document.write( "2. Find the square root of 1515.\r\n" );
document.write( "\r\n" );
document.write( "3. You will get 38.92300091\r\n" );
document.write( "\r\n" );
document.write( "4. Take the next higher whole number to that, which is 39\r\n" );
document.write( "\r\n" );
document.write( "5. Square 39.  That is, multiply 39x39\r\n" );
document.write( "\r\n" );
document.write( "6. You will get 1521, which is a perfect square, since it is 39²\r\n" );
document.write( "\r\n" );
document.write( "7. Subtract 1521 - 1515\r\n" );
document.write( "\r\n" );
document.write( "8. You will get 6.\r\n" );
document.write( "\r\n" );
document.write( "9. The answer is 6, because 6 is how much you will have to add to\r\n" );
document.write( "1515 to get the first perfect square which is greater than 1515, \r\n" );
document.write( "which is 1521.\r\n" );
