OK, let's work through this together. We're starting with 865 and we're going to multiply it by 6, which means we add 865 to itself 6 times.
Step 1: 0 + 865 = 865
Step 2: 865 + 865 = 1730
Step 3: 1730 + 865 = 2595
Step 4: 2595 + 865 = 3460
Step 5: 3460 + 865 = 4325
Step 6: 4325 + 865 = 5190

So, 865*6 = 5190
