OK, let's work through this together. We're starting with 574 and we're going to multiply it by 6, which means we add 574 to itself 6 times.
Step 1: 0 + 574 = 574
Step 2: 574 + 574 = 1148
Step 3: 1148 + 574 = 1722
Step 4: 1722 + 574 = 2296
Step 5: 2296 + 574 = 2870
Step 6: 2870 + 574 = 3444

So, 574*6 = 3444
