Sure thing, let's get straight to it. We start with 437 and we're going to multiply it by 13, which means adding 437 to itself 13 times.
Step 1: 0 + 437 = 437
Step 2: 437 + 437 = 874
Step 3: 874 + 437 = 1311
Step 4: 1311 + 437 = 1748
Step 5: 1748 + 437 = 2185
Step 6: 2185 + 437 = 2622
Step 7: 2622 + 437 = 3059
Step 8: 3059 + 437 = 3496
Step 9: 3496 + 437 = 3933
Step 10: 3933 + 437 = 4370
Step 11: 4370 + 437 = 4807
Step 12: 4807 + 437 = 5244
Step 13: 5244 + 437 = 5681

So, 437*13 = 5681
