OK, let's crack this. We're given 121 and our task is to multiply it by 8. Essentially, we'll be adding 121 to itself 8 times.
Step 1: 0 + 121 = 121
Step 2: 121 + 121 = 242
Step 3: 242 + 121 = 363
Step 4: 363 + 121 = 484
Step 5: 484 + 121 = 605
Step 6: 605 + 121 = 726
Step 7: 726 + 121 = 847
Step 8: 847 + 121 = 968

So, 121*8 = 968
