OK, let's crack this. We're given 934 and our task is to multiply it by 12. Essentially, we'll be adding 934 to itself 12 times.
Step 1: 0 + 934 = 934
Step 2: 934 + 934 = 1868
Step 3: 1868 + 934 = 2802
Step 4: 2802 + 934 = 3736
Step 5: 3736 + 934 = 4670
Step 6: 4670 + 934 = 5604
Step 7: 5604 + 934 = 6538
Step 8: 6538 + 934 = 7472
Step 9: 7472 + 934 = 8406
Step 10: 8406 + 934 = 9340
Step 11: 9340 + 934 = 10274
Step 12: 10274 + 934 = 11208

So, 934*12 = 11208
