OK, let's work through this together. We're starting with 993 and we're going to multiply it by 36, which means we add 993 to itself 36 times.
Step 1: 0 + 993 = 993
Step 2: 993 + 993 = 1986
Step 3: 1986 + 993 = 2979
Step 4: 2979 + 993 = 3972
Step 5: 3972 + 993 = 4965
Step 6: 4965 + 993 = 5958
Step 7: 5958 + 993 = 6951
Step 8: 6951 + 993 = 7944
Step 9: 7944 + 993 = 8937
Step 10: 8937 + 993 = 9930
Step 11: 9930 + 993 = 10923
Step 12: 10923 + 993 = 11916
Step 13: 11916 + 993 = 12909
Step 14: 12909 + 993 = 13902
Step 15: 13902 + 993 = 14895
Step 16: 14895 + 993 = 15888
Step 17: 15888 + 993 = 16881
Step 18: 16881 + 993 = 17874
Step 19: 17874 + 993 = 18867
Step 20: 18867 + 993 = 19860
Step 21: 19860 + 993 = 20853
Step 22: 20853 + 993 = 21846
Step 23: 21846 + 993 = 22839
Step 24: 22839 + 993 = 23832
Step 25: 23832 + 993 = 24825
Step 26: 24825 + 993 = 25818
Step 27: 25818 + 993 = 26811
Step 28: 26811 + 993 = 27804
Step 29: 27804 + 993 = 28797
Step 30: 28797 + 993 = 29790
Step 31: 29790 + 993 = 30783
Step 32: 30783 + 993 = 31776
Step 33: 31776 + 993 = 32769
Step 34: 32769 + 993 = 33762
Step 35: 33762 + 993 = 34755
Step 36: 34755 + 993 = 35748

So, 993*36 = 35748
