Let's get this math done. We have 622 and we're going to multiply it by 33. This is the same as taking 622 and adding it to itself 33 times.
Step 1: 0 + 622 = 622
Step 2: 622 + 622 = 1244
Step 3: 1244 + 622 = 1866
Step 4: 1866 + 622 = 2488
Step 5: 2488 + 622 = 3110
Step 6: 3110 + 622 = 3732
Step 7: 3732 + 622 = 4354
Step 8: 4354 + 622 = 4976
Step 9: 4976 + 622 = 5598
Step 10: 5598 + 622 = 6220
Step 11: 6220 + 622 = 6842
Step 12: 6842 + 622 = 7464
Step 13: 7464 + 622 = 8086
Step 14: 8086 + 622 = 8708
Step 15: 8708 + 622 = 9330
Step 16: 9330 + 622 = 9952
Step 17: 9952 + 622 = 10574
Step 18: 10574 + 622 = 11196
Step 19: 11196 + 622 = 11818
Step 20: 11818 + 622 = 12440
Step 21: 12440 + 622 = 13062
Step 22: 13062 + 622 = 13684
Step 23: 13684 + 622 = 14306
Step 24: 14306 + 622 = 14928
Step 25: 14928 + 622 = 15550
Step 26: 15550 + 622 = 16172
Step 27: 16172 + 622 = 16794
Step 28: 16794 + 622 = 17416
Step 29: 17416 + 622 = 18038
Step 30: 18038 + 622 = 18660
Step 31: 18660 + 622 = 19282
Step 32: 19282 + 622 = 19904
Step 33: 19904 + 622 = 20526

So, 622*33 = 20526
