 How many stars are printed out? How many times do the loops iterate? The outer loop runs 5 times and the inner loop runs 0, 1, 2, 3, 4, 5 times respectively. So, the number of stars printed are 0 + 1 + 2 + 3 + 4 + 5 = 15. Notice that this is the sum of a series of natural numbers from 0 to 5. 
 
 There is a neat formula to calculate the sum of n natural numbers: ``n(n+1)/2`` where n is the number of times the outer loop runs or the maximum number of times the inner loop runs. So, for the example above, the outer loop runs 5 times (and the inner loop runs 0 to a maximum of 5 times) so for n=5, the inner loop runs 5(5+1)/2 = 15 times.
