Sure thing, let's get straight to it. We start with 486 and we're going to multiply it by 19, which means adding 486 to itself 19 times.
Step 1: 0 + 486 = 486
Step 2: 486 + 486 = 972
Step 3: 972 + 486 = 1458
Step 4: 1458 + 486 = 1944
Step 5: 1944 + 486 = 2430
Step 6: 2430 + 486 = 2916
Step 7: 2916 + 486 = 3402
Step 8: 3402 + 486 = 3888
Step 9: 3888 + 486 = 4374
Step 10: 4374 + 486 = 4860
Step 11: 4860 + 486 = 5346
Step 12: 5346 + 486 = 5832
Step 13: 5832 + 486 = 6318
Step 14: 6318 + 486 = 6804
Step 15: 6804 + 486 = 7290
Step 16: 7290 + 486 = 7776
Step 17: 7776 + 486 = 8262
Step 18: 8262 + 486 = 8748
Step 19: 8748 + 486 = 9234

So, 486*19 = 9234
