Let's roll up our sleeves and solve this. We have 933 and we're going to multiply it by 22, essentially adding 933 to itself 22 times.
Step 1: 0 + 933 = 933
Step 2: 933 + 933 = 1866
Step 3: 1866 + 933 = 2799
Step 4: 2799 + 933 = 3732
Step 5: 3732 + 933 = 4665
Step 6: 4665 + 933 = 5598
Step 7: 5598 + 933 = 6531
Step 8: 6531 + 933 = 7464
Step 9: 7464 + 933 = 8397
Step 10: 8397 + 933 = 9330
Step 11: 9330 + 933 = 10263
Step 12: 10263 + 933 = 11196
Step 13: 11196 + 933 = 12129
Step 14: 12129 + 933 = 13062
Step 15: 13062 + 933 = 13995
Step 16: 13995 + 933 = 14928
Step 17: 14928 + 933 = 15861
Step 18: 15861 + 933 = 16794
Step 19: 16794 + 933 = 17727
Step 20: 17727 + 933 = 18660
Step 21: 18660 + 933 = 19593
Step 22: 19593 + 933 = 20526

So, 933*22 = 20526
