Sure thing, let's get straight to it. We start with 797 and we're going to multiply it by 17, which means adding 797 to itself 17 times.
Step 1: 0 + 797 = 797
Step 2: 797 + 797 = 1594
Step 3: 1594 + 797 = 2391
Step 4: 2391 + 797 = 3188
Step 5: 3188 + 797 = 3985
Step 6: 3985 + 797 = 4782
Step 7: 4782 + 797 = 5579
Step 8: 5579 + 797 = 6376
Step 9: 6376 + 797 = 7173
Step 10: 7173 + 797 = 7970
Step 11: 7970 + 797 = 8767
Step 12: 8767 + 797 = 9564
Step 13: 9564 + 797 = 10361
Step 14: 10361 + 797 = 11158
Step 15: 11158 + 797 = 11955
Step 16: 11955 + 797 = 12752
Step 17: 12752 + 797 = 13549

So, 797*17 = 13549
