OK, let's work through this together. We're starting with 66 and we're going to multiply it by 17, which means we add 66 to itself 17 times.
Step 1: 0 + 66 = 66
Step 2: 66 + 66 = 132
Step 3: 132 + 66 = 198
Step 4: 198 + 66 = 264
Step 5: 264 + 66 = 330
Step 6: 330 + 66 = 396
Step 7: 396 + 66 = 462
Step 8: 462 + 66 = 528
Step 9: 528 + 66 = 594
Step 10: 594 + 66 = 660
Step 11: 660 + 66 = 726
Step 12: 726 + 66 = 792
Step 13: 792 + 66 = 858
Step 14: 858 + 66 = 924
Step 15: 924 + 66 = 990
Step 16: 990 + 66 = 1056
Step 17: 1056 + 66 = 1122

So, 66*17 = 1122
