Let's get this math done. We have 550 and we're going to multiply it by 16. This is the same as taking 550 and adding it to itself 16 times.
Step 1: 0 + 550 = 550
Step 2: 550 + 550 = 1100
Step 3: 1100 + 550 = 1650
Step 4: 1650 + 550 = 2200
Step 5: 2200 + 550 = 2750
Step 6: 2750 + 550 = 3300
Step 7: 3300 + 550 = 3850
Step 8: 3850 + 550 = 4400
Step 9: 4400 + 550 = 4950
Step 10: 4950 + 550 = 5500
Step 11: 5500 + 550 = 6050
Step 12: 6050 + 550 = 6600
Step 13: 6600 + 550 = 7150
Step 14: 7150 + 550 = 7700
Step 15: 7700 + 550 = 8250
Step 16: 8250 + 550 = 8800

So, 550*16 = 8800
