Let's roll up our sleeves and solve this. We have 971 and we're going to multiply it by 12, essentially adding 971 to itself 12 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

So, 971*12 = 11652
