Sure thing, let's get straight to it. We start with 633 and we're going to multiply it by 33, which means adding 633 to itself 33 times.
Step 1: 0 + 633 = 633
Step 2: 633 + 633 = 1266
Step 3: 1266 + 633 = 1899
Step 4: 1899 + 633 = 2532
Step 5: 2532 + 633 = 3165
Step 6: 3165 + 633 = 3798
Step 7: 3798 + 633 = 4431
Step 8: 4431 + 633 = 5064
Step 9: 5064 + 633 = 5697
Step 10: 5697 + 633 = 6330
Step 11: 6330 + 633 = 6963
Step 12: 6963 + 633 = 7596
Step 13: 7596 + 633 = 8229
Step 14: 8229 + 633 = 8862
Step 15: 8862 + 633 = 9495
Step 16: 9495 + 633 = 10128
Step 17: 10128 + 633 = 10761
Step 18: 10761 + 633 = 11394
Step 19: 11394 + 633 = 12027
Step 20: 12027 + 633 = 12660
Step 21: 12660 + 633 = 13293
Step 22: 13293 + 633 = 13926
Step 23: 13926 + 633 = 14559
Step 24: 14559 + 633 = 15192
Step 25: 15192 + 633 = 15825
Step 26: 15825 + 633 = 16458
Step 27: 16458 + 633 = 17091
Step 28: 17091 + 633 = 17724
Step 29: 17724 + 633 = 18357
Step 30: 18357 + 633 = 18990
Step 31: 18990 + 633 = 19623
Step 32: 19623 + 633 = 20256
Step 33: 20256 + 633 = 20889

So, 633*33 = 20889
