OK, let's work through this together. We're starting with 526 and we're going to multiply it by 6, which means we add 526 to itself 6 times.
Step 1: 0 + 526 = 526
Step 2: 526 + 526 = 1052
Step 3: 1052 + 526 = 1578
Step 4: 1578 + 526 = 2104
Step 5: 2104 + 526 = 2630
Step 6: 2630 + 526 = 3156

So, 526*6 = 3156
