OK, let's work through this together. We're starting with 675 and we're going to multiply it by 17, which means we add 675 to itself 17 times.
Step 1: 0 + 675 = 675
Step 2: 675 + 675 = 1350
Step 3: 1350 + 675 = 2025
Step 4: 2025 + 675 = 2700
Step 5: 2700 + 675 = 3375
Step 6: 3375 + 675 = 4050
Step 7: 4050 + 675 = 4725
Step 8: 4725 + 675 = 5400
Step 9: 5400 + 675 = 6075
Step 10: 6075 + 675 = 6750
Step 11: 6750 + 675 = 7425
Step 12: 7425 + 675 = 8100
Step 13: 8100 + 675 = 8775
Step 14: 8775 + 675 = 9450
Step 15: 9450 + 675 = 10125
Step 16: 10125 + 675 = 10800
Step 17: 10800 + 675 = 11475

So, 675*17 = 11475
