Let's roll up our sleeves and solve this. We have 284 and we're going to multiply it by 19, essentially adding 284 to itself 19 times.
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

So, 284*19 = 5396
