Sure thing! We've got 759 and we're gonna multiply it by 15. That's the same as adding 759 to itself 15 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

So, 759*15 = 11385
