Let's roll up our sleeves and solve this. We have 986 and we're going to multiply it by 10, essentially adding 986 to itself 10 times.
Step 1: 0 + 986 = 986
Step 2: 986 + 986 = 1972
Step 3: 1972 + 986 = 2958
Step 4: 2958 + 986 = 3944
Step 5: 3944 + 986 = 4930
Step 6: 4930 + 986 = 5916
Step 7: 5916 + 986 = 6902
Step 8: 6902 + 986 = 7888
Step 9: 7888 + 986 = 8874
Step 10: 8874 + 986 = 9860

So, 986*10 = 9860
