OK, let's crack this. We're given 581 and our task is to multiply it by 12. Essentially, we'll be adding 581 to itself 12 times.
Step 1: 0 + 581 = 581
Step 2: 581 + 581 = 1162
Step 3: 1162 + 581 = 1743
Step 4: 1743 + 581 = 2324
Step 5: 2324 + 581 = 2905
Step 6: 2905 + 581 = 3486
Step 7: 3486 + 581 = 4067
Step 8: 4067 + 581 = 4648
Step 9: 4648 + 581 = 5229
Step 10: 5229 + 581 = 5810
Step 11: 5810 + 581 = 6391
Step 12: 6391 + 581 = 6972

So, 581*12 = 6972
