Sure thing! We've got 419 and we're gonna multiply it by 18. That's the same as adding 419 to itself 18 times.
Step 1: 0 + 419 = 419
Step 2: 419 + 419 = 838
Step 3: 838 + 419 = 1257
Step 4: 1257 + 419 = 1676
Step 5: 1676 + 419 = 2095
Step 6: 2095 + 419 = 2514
Step 7: 2514 + 419 = 2933
Step 8: 2933 + 419 = 3352
Step 9: 3352 + 419 = 3771
Step 10: 3771 + 419 = 4190
Step 11: 4190 + 419 = 4609
Step 12: 4609 + 419 = 5028
Step 13: 5028 + 419 = 5447
Step 14: 5447 + 419 = 5866
Step 15: 5866 + 419 = 6285
Step 16: 6285 + 419 = 6704
Step 17: 6704 + 419 = 7123
Step 18: 7123 + 419 = 7542

So, 419*18 = 7542
