OK, let's work through this together. We're starting with 552 and we're going to multiply it by 6, which means we add 552 to itself 6 times.
Step 1: 0 + 552 = 552
Step 2: 552 + 552 = 1104
Step 3: 1104 + 552 = 1656
Step 4: 1656 + 552 = 2208
Step 5: 2208 + 552 = 2760
Step 6: 2760 + 552 = 3312

So, 552*6 = 3312
