Let's roll up our sleeves and solve this. We have 529 and we're going to multiply it by 12, essentially adding 529 to itself 12 times.
Step 1: 0 + 529 = 529
Step 2: 529 + 529 = 1058
Step 3: 1058 + 529 = 1587
Step 4: 1587 + 529 = 2116
Step 5: 2116 + 529 = 2645
Step 6: 2645 + 529 = 3174
Step 7: 3174 + 529 = 3703
Step 8: 3703 + 529 = 4232
Step 9: 4232 + 529 = 4761
Step 10: 4761 + 529 = 5290
Step 11: 5290 + 529 = 5819
Step 12: 5819 + 529 = 6348

So, 529*12 = 6348
