Step 1: 0 + 284 = 284
Step 2: 284 + 284 = 568
Step 3: 568 + 284 = 852
Step 4: 852 + 284 = 1136
Step 5: 1136 + 284 = 1420
Step 6: 1420 + 284 = 1704
Step 7: 1704 + 284 = 1988
Step 8: 1988 + 284 = 2272
Step 9: 2272 + 284 = 2556
Step 10: 2556 + 284 = 2840
Step 11: 2840 + 284 = 3124
Step 12: 3124 + 284 = 3408
Step 13: 3408 + 284 = 3692
Step 14: 3692 + 284 = 3976
Step 15: 3976 + 284 = 4260
Step 16: 4260 + 284 = 4544
Step 17: 4544 + 284 = 4828
Step 18: 4828 + 284 = 5112
Step 19: 5112 + 284 = 5396
Step 20: 5396 + 284 = 5680
Step 21: 5680 + 284 = 5964
Step 22: 5964 + 284 = 6248
Step 23: 6248 + 284 = 6532
Step 24: 6532 + 284 = 6816
Step 25: 6816 + 284 = 7100
Step 26: 7100 + 284 = 7384
Step 27: 7384 + 284 = 7668
Step 28: 7668 + 284 = 7952
Step 29: 7952 + 284 = 8236
Step 30: 8236 + 284 = 8520
Step 31: 8520 + 284 = 8804
Step 32: 8804 + 284 = 9088
Step 33: 9088 + 284 = 9372
Step 34: 9372 + 284 = 9656
Step 35: 9656 + 284 = 9940
Step 36: 9940 + 284 = 10224
Step 37: 10224 + 284 = 10508
Step 38: 10508 + 284 = 10792
Step 39: 10792 + 284 = 11076
Step 40: 11076 + 284 = 11360
Step 41: 11360 + 284 = 11644
Step 42: 11644 + 284 = 11928

So, 284*42 = 11928
