OK, let's crack this. We're given 733 and our task is to multiply it by 15. Essentially, we'll be adding 733 to itself 15 times.
Step 1: 0 + 733 = 733
Step 2: 733 + 733 = 1466
Step 3: 1466 + 733 = 2199
Step 4: 2199 + 733 = 2932
Step 5: 2932 + 733 = 3665
Step 6: 3665 + 733 = 4398
Step 7: 4398 + 733 = 5131
Step 8: 5131 + 733 = 5864
Step 9: 5864 + 733 = 6597
Step 10: 6597 + 733 = 7330
Step 11: 7330 + 733 = 8063
Step 12: 8063 + 733 = 8796
Step 13: 8796 + 733 = 9529
Step 14: 9529 + 733 = 10262
Step 15: 10262 + 733 = 10995

So, 733*15 = 10995
