OK, let's work through this together. We're starting with 554 and we're going to multiply it by 6, which means we add 554 to itself 6 times.
Step 1: 0 + 554 = 554
Step 2: 554 + 554 = 1108
Step 3: 1108 + 554 = 1662
Step 4: 1662 + 554 = 2216
Step 5: 2216 + 554 = 2770
Step 6: 2770 + 554 = 3324

So, 554*6 = 3324
