OK, let's work through this together. We're starting with 363 and we're going to multiply it by 13, which means we add 363 to itself 13 times.
Step 1: 0 + 363 = 363
Step 2: 363 + 363 = 726
Step 3: 726 + 363 = 1089
Step 4: 1089 + 363 = 1452
Step 5: 1452 + 363 = 1815
Step 6: 1815 + 363 = 2178
Step 7: 2178 + 363 = 2541
Step 8: 2541 + 363 = 2904
Step 9: 2904 + 363 = 3267
Step 10: 3267 + 363 = 3630
Step 11: 3630 + 363 = 3993
Step 12: 3993 + 363 = 4356
Step 13: 4356 + 363 = 4719

So, 363*13 = 4719
