Sure thing! We've got 381 and we're gonna multiply it by 11. That's the same as adding 381 to itself 11 times.
Step 1: 0 + 381 = 381
Step 2: 381 + 381 = 762
Step 3: 762 + 381 = 1143
Step 4: 1143 + 381 = 1524
Step 5: 1524 + 381 = 1905
Step 6: 1905 + 381 = 2286
Step 7: 2286 + 381 = 2667
Step 8: 2667 + 381 = 3048
Step 9: 3048 + 381 = 3429
Step 10: 3429 + 381 = 3810
Step 11: 3810 + 381 = 4191

So, 381*11 = 4191
