Alright, let's solve this math problem step by step. First, we have the number 993. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 23. So, we're going to take the number 993 and add it to itself 23 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

So, 993*23 = 22839
