Let's get this math done. We have 759 and we're going to multiply it by 18. This is the same as taking 759 and adding it to itself 18 times.
Step 1: 0 + 759 = 759
Step 2: 759 + 759 = 1518
Step 3: 1518 + 759 = 2277
Step 4: 2277 + 759 = 3036
Step 5: 3036 + 759 = 3795
Step 6: 3795 + 759 = 4554
Step 7: 4554 + 759 = 5313
Step 8: 5313 + 759 = 6072
Step 9: 6072 + 759 = 6831
Step 10: 6831 + 759 = 7590
Step 11: 7590 + 759 = 8349
Step 12: 8349 + 759 = 9108
Step 13: 9108 + 759 = 9867
Step 14: 9867 + 759 = 10626
Step 15: 10626 + 759 = 11385
Step 16: 11385 + 759 = 12144
Step 17: 12144 + 759 = 12903
Step 18: 12903 + 759 = 13662

So, 759*18 = 13662
