Those numbers are the average number of processes in the run queue (ie:
waiting for a CPU time slice) over the past 1, 5 and 15 minute(s),
respectivly. Ie:

7:31  up 2 days, 18:44,  3 users, load average: 0.17, 0.04, 0.00
 
means that at 7:31pm, there was an average of:               
     0.17 processes waiting for the CPU in the past minute,
     0.04  "        "               "      "      " 5 minutes and
     0.00  "        "               "      "      " 15 minutes.
