Let's roll up our sleeves and solve this. We have 992 and we're going to multiply it by 9, essentially adding 992 to itself 9 times.
Step 1: 0 + 992 = 992
Step 2: 992 + 992 = 1984
Step 3: 1984 + 992 = 2976
Step 4: 2976 + 992 = 3968
Step 5: 3968 + 992 = 4960
Step 6: 4960 + 992 = 5952
Step 7: 5952 + 992 = 6944
Step 8: 6944 + 992 = 7936
Step 9: 7936 + 992 = 8928

So, 992*9 = 8928
