Alright, let's solve this math problem step by step. First, we have the number 633. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 27. So, we're going to take the number 633 and add it to itself 27 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

So, 633*27 = 17091
