OK, let's crack this. We're given 556 and our task is to multiply it by 7. Essentially, we'll be adding 556 to itself 7 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

So, 556*7 = 3892
