OK, let's work through this together. We're starting with 584 and we're going to multiply it by 6, which means we add 584 to itself 6 times.
Step 1: 0 + 584 = 584
Step 2: 584 + 584 = 1168
Step 3: 1168 + 584 = 1752
Step 4: 1752 + 584 = 2336
Step 5: 2336 + 584 = 2920
Step 6: 2920 + 584 = 3504

So, 584*6 = 3504
