Let's get this math done. We have 264 and we're going to multiply it by 13. This is the same as taking 264 and adding it to itself 13 times.
Step 1: 0 + 264 = 264
Step 2: 264 + 264 = 528
Step 3: 528 + 264 = 792
Step 4: 792 + 264 = 1056
Step 5: 1056 + 264 = 1320
Step 6: 1320 + 264 = 1584
Step 7: 1584 + 264 = 1848
Step 8: 1848 + 264 = 2112
Step 9: 2112 + 264 = 2376
Step 10: 2376 + 264 = 2640
Step 11: 2640 + 264 = 2904
Step 12: 2904 + 264 = 3168
Step 13: 3168 + 264 = 3432

So, 264*13 = 3432
