Without delay, let's solve this. We've got 987 and we will be multiplying it by 33, that is, adding 987 to itself 33 times.
Step 1: 0 + 987 = 987
Step 2: 987 + 987 = 1974
Step 3: 1974 + 987 = 2961
Step 4: 2961 + 987 = 3948
Step 5: 3948 + 987 = 4935
Step 6: 4935 + 987 = 5922
Step 7: 5922 + 987 = 6909
Step 8: 6909 + 987 = 7896
Step 9: 7896 + 987 = 8883
Step 10: 8883 + 987 = 9870
Step 11: 9870 + 987 = 10857
Step 12: 10857 + 987 = 11844
Step 13: 11844 + 987 = 12831
Step 14: 12831 + 987 = 13818
Step 15: 13818 + 987 = 14805
Step 16: 14805 + 987 = 15792
Step 17: 15792 + 987 = 16779
Step 18: 16779 + 987 = 17766
Step 19: 17766 + 987 = 18753
Step 20: 18753 + 987 = 19740
Step 21: 19740 + 987 = 20727
Step 22: 20727 + 987 = 21714
Step 23: 21714 + 987 = 22701
Step 24: 22701 + 987 = 23688
Step 25: 23688 + 987 = 24675
Step 26: 24675 + 987 = 25662
Step 27: 25662 + 987 = 26649
Step 28: 26649 + 987 = 27636
Step 29: 27636 + 987 = 28623
Step 30: 28623 + 987 = 29610
Step 31: 29610 + 987 = 30597
Step 32: 30597 + 987 = 31584
Step 33: 31584 + 987 = 32571

So, 987*33 = 32571
