Let's roll up our sleeves and solve this. We have 291 and we're going to multiply it by 22, essentially adding 291 to itself 22 times.
Step 1: 0 + 291 = 291
Step 2: 291 + 291 = 582
Step 3: 582 + 291 = 873
Step 4: 873 + 291 = 1164
Step 5: 1164 + 291 = 1455
Step 6: 1455 + 291 = 1746
Step 7: 1746 + 291 = 2037
Step 8: 2037 + 291 = 2328
Step 9: 2328 + 291 = 2619
Step 10: 2619 + 291 = 2910
Step 11: 2910 + 291 = 3201
Step 12: 3201 + 291 = 3492
Step 13: 3492 + 291 = 3783
Step 14: 3783 + 291 = 4074
Step 15: 4074 + 291 = 4365
Step 16: 4365 + 291 = 4656
Step 17: 4656 + 291 = 4947
Step 18: 4947 + 291 = 5238
Step 19: 5238 + 291 = 5529
Step 20: 5529 + 291 = 5820
Step 21: 5820 + 291 = 6111
Step 22: 6111 + 291 = 6402

So, 291*22 = 6402
