OK, let's work through this together. We're starting with 396 and we're going to multiply it by 6, which means we add 396 to itself 6 times.
Step 1: 0 + 396 = 396
Step 2: 396 + 396 = 792
Step 3: 792 + 396 = 1188
Step 4: 1188 + 396 = 1584
Step 5: 1584 + 396 = 1980
Step 6: 1980 + 396 = 2376

So, 396*6 = 2376
