OK, let's work through this together. We're starting with 381 and we're going to multiply it by 22, which means we add 381 to itself 22 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
Step 12: 4191 + 381 = 4572
Step 13: 4572 + 381 = 4953
Step 14: 4953 + 381 = 5334
Step 15: 5334 + 381 = 5715
Step 16: 5715 + 381 = 6096
Step 17: 6096 + 381 = 6477
Step 18: 6477 + 381 = 6858
Step 19: 6858 + 381 = 7239
Step 20: 7239 + 381 = 7620
Step 21: 7620 + 381 = 8001
Step 22: 8001 + 381 = 8382

So, 381*22 = 8382
