OK, let's work through this together. We're starting with 556 and we're going to multiply it by 8, which means we add 556 to itself 8 times.
Step 1: 0 + 556 = 556
Step 2: 556 + 556 = 1112
Step 3: 1112 + 556 = 1668
Step 4: 1668 + 556 = 2224
Step 5: 2224 + 556 = 2780
Step 6: 2780 + 556 = 3336
Step 7: 3336 + 556 = 3892
Step 8: 3892 + 556 = 4448

So, 556*8 = 4448
