OK, let's crack this. We're given 440 and our task is to multiply it by 13. Essentially, we'll be adding 440 to itself 13 times.
Step 1: 0 + 440 = 440
Step 2: 440 + 440 = 880
Step 3: 880 + 440 = 1320
Step 4: 1320 + 440 = 1760
Step 5: 1760 + 440 = 2200
Step 6: 2200 + 440 = 2640
Step 7: 2640 + 440 = 3080
Step 8: 3080 + 440 = 3520
Step 9: 3520 + 440 = 3960
Step 10: 3960 + 440 = 4400
Step 11: 4400 + 440 = 4840
Step 12: 4840 + 440 = 5280
Step 13: 5280 + 440 = 5720

So, 440*13 = 5720
