Sure thing, let's get straight to it. We start with 139 and we're going to multiply it by 8, which means adding 139 to itself 8 times.
Step 1: 0 + 139 = 139
Step 2: 139 + 139 = 278
Step 3: 278 + 139 = 417
Step 4: 417 + 139 = 556
Step 5: 556 + 139 = 695
Step 6: 695 + 139 = 834
Step 7: 834 + 139 = 973
Step 8: 973 + 139 = 1112

So, 139*8 = 1112
