Let's roll up our sleeves and solve this. We have 984 and we're going to multiply it by 12, essentially adding 984 to itself 12 times.
Step 1: 0 + 984 = 984
Step 2: 984 + 984 = 1968
Step 3: 1968 + 984 = 2952
Step 4: 2952 + 984 = 3936
Step 5: 3936 + 984 = 4920
Step 6: 4920 + 984 = 5904
Step 7: 5904 + 984 = 6888
Step 8: 6888 + 984 = 7872
Step 9: 7872 + 984 = 8856
Step 10: 8856 + 984 = 9840
Step 11: 9840 + 984 = 10824
Step 12: 10824 + 984 = 11808

So, 984*12 = 11808
