OK, let's work through this together. We're starting with 971 and we're going to multiply it by 16, which means we add 971 to itself 16 times.
Step 1: 0 + 971 = 971
Step 2: 971 + 971 = 1942
Step 3: 1942 + 971 = 2913
Step 4: 2913 + 971 = 3884
Step 5: 3884 + 971 = 4855
Step 6: 4855 + 971 = 5826
Step 7: 5826 + 971 = 6797
Step 8: 6797 + 971 = 7768
Step 9: 7768 + 971 = 8739
Step 10: 8739 + 971 = 9710
Step 11: 9710 + 971 = 10681
Step 12: 10681 + 971 = 11652
Step 13: 11652 + 971 = 12623
Step 14: 12623 + 971 = 13594
Step 15: 13594 + 971 = 14565
Step 16: 14565 + 971 = 15536

So, 971*16 = 15536
