OK, let's crack this. We're given 558 and our task is to multiply it by 8. Essentially, we'll be adding 558 to itself 8 times.
Step 1: 0 + 558 = 558
Step 2: 558 + 558 = 1116
Step 3: 1116 + 558 = 1674
Step 4: 1674 + 558 = 2232
Step 5: 2232 + 558 = 2790
Step 6: 2790 + 558 = 3348
Step 7: 3348 + 558 = 3906
Step 8: 3906 + 558 = 4464

So, 558*8 = 4464
