Let's get this math done. We have 925 and we're going to multiply it by 18. This is the same as taking 925 and adding it to itself 18 times.
Step 1: 0 + 925 = 925
Step 2: 925 + 925 = 1850
Step 3: 1850 + 925 = 2775
Step 4: 2775 + 925 = 3700
Step 5: 3700 + 925 = 4625
Step 6: 4625 + 925 = 5550
Step 7: 5550 + 925 = 6475
Step 8: 6475 + 925 = 7400
Step 9: 7400 + 925 = 8325
Step 10: 8325 + 925 = 9250
Step 11: 9250 + 925 = 10175
Step 12: 10175 + 925 = 11100
Step 13: 11100 + 925 = 12025
Step 14: 12025 + 925 = 12950
Step 15: 12950 + 925 = 13875
Step 16: 13875 + 925 = 14800
Step 17: 14800 + 925 = 15725
Step 18: 15725 + 925 = 16650

So, 925*18 = 16650
