Let's get this math done. We have 994 and we're going to multiply it by 10. This is the same as taking 994 and adding it to itself 10 times.
Step 1: 0 + 994 = 994
Step 2: 994 + 994 = 1988
Step 3: 1988 + 994 = 2982
Step 4: 2982 + 994 = 3976
Step 5: 3976 + 994 = 4970
Step 6: 4970 + 994 = 5964
Step 7: 5964 + 994 = 6958
Step 8: 6958 + 994 = 7952
Step 9: 7952 + 994 = 8946
Step 10: 8946 + 994 = 9940

So, 994*10 = 9940
