OK, let's crack this. We're given 763 and our task is to multiply it by 17. Essentially, we'll be adding 763 to itself 17 times.
Step 1: 0 + 763 = 763
Step 2: 763 + 763 = 1526
Step 3: 1526 + 763 = 2289
Step 4: 2289 + 763 = 3052
Step 5: 3052 + 763 = 3815
Step 6: 3815 + 763 = 4578
Step 7: 4578 + 763 = 5341
Step 8: 5341 + 763 = 6104
Step 9: 6104 + 763 = 6867
Step 10: 6867 + 763 = 7630
Step 11: 7630 + 763 = 8393
Step 12: 8393 + 763 = 9156
Step 13: 9156 + 763 = 9919
Step 14: 9919 + 763 = 10682
Step 15: 10682 + 763 = 11445
Step 16: 11445 + 763 = 12208
Step 17: 12208 + 763 = 12971

So, 763*17 = 12971
