Let's get this math done. We have 930 and we're going to multiply it by 13. This is the same as taking 930 and adding it to itself 13 times.
Step 1: 0 + 930 = 930
Step 2: 930 + 930 = 1860
Step 3: 1860 + 930 = 2790
Step 4: 2790 + 930 = 3720
Step 5: 3720 + 930 = 4650
Step 6: 4650 + 930 = 5580
Step 7: 5580 + 930 = 6510
Step 8: 6510 + 930 = 7440
Step 9: 7440 + 930 = 8370
Step 10: 8370 + 930 = 9300
Step 11: 9300 + 930 = 10230
Step 12: 10230 + 930 = 11160
Step 13: 11160 + 930 = 12090

So, 930*13 = 12090
