Sure thing, let's get straight to it. We start with 396 and we're going to multiply it by 13, which means adding 396 to itself 13 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
Step 7: 2376 + 396 = 2772
Step 8: 2772 + 396 = 3168
Step 9: 3168 + 396 = 3564
Step 10: 3564 + 396 = 3960
Step 11: 3960 + 396 = 4356
Step 12: 4356 + 396 = 4752
Step 13: 4752 + 396 = 5148

So, 396*13 = 5148
