Without delay, let's solve this. We've got 474 and we will be multiplying it by 21, that is, adding 474 to itself 21 times.
Step 1: 0 + 474 = 474
Step 2: 474 + 474 = 948
Step 3: 948 + 474 = 1422
Step 4: 1422 + 474 = 1896
Step 5: 1896 + 474 = 2370
Step 6: 2370 + 474 = 2844
Step 7: 2844 + 474 = 3318
Step 8: 3318 + 474 = 3792
Step 9: 3792 + 474 = 4266
Step 10: 4266 + 474 = 4740
Step 11: 4740 + 474 = 5214
Step 12: 5214 + 474 = 5688
Step 13: 5688 + 474 = 6162
Step 14: 6162 + 474 = 6636
Step 15: 6636 + 474 = 7110
Step 16: 7110 + 474 = 7584
Step 17: 7584 + 474 = 8058
Step 18: 8058 + 474 = 8532
Step 19: 8532 + 474 = 9006
Step 20: 9006 + 474 = 9480
Step 21: 9480 + 474 = 9954

So, 474*21 = 9954
