document.write( "\r\n" );
document.write( "Each possible trip has four stops.\r\n" );
document.write( "There are 4 ways to choose the first city on the route.\r\n" );
document.write( "After you've chosen the first city, there are 3 ways to choose the second city.\r\n" );
document.write( "Likewise, there are 2 ways to choose the third city.\r\n" );
document.write( "There is only one city left to be the fourth city on your route.\r\n" );
document.write( "\r\n" );
document.write( "Using the Fundamental Principle of Counting, we multiply\r\n" );
document.write( "4*3*2*1 = 24\r\n" );
document.write( "\r\n" );
document.write( "There are 24 different routes possible.\r\n" );
