Without delay, let's solve this. We've got 307 and we will be multiplying it by 17, that is, adding 307 to itself 17 times.
Step 1: 0 + 307 = 307
Step 2: 307 + 307 = 614
Step 3: 614 + 307 = 921
Step 4: 921 + 307 = 1228
Step 5: 1228 + 307 = 1535
Step 6: 1535 + 307 = 1842
Step 7: 1842 + 307 = 2149
Step 8: 2149 + 307 = 2456
Step 9: 2456 + 307 = 2763
Step 10: 2763 + 307 = 3070
Step 11: 3070 + 307 = 3377
Step 12: 3377 + 307 = 3684
Step 13: 3684 + 307 = 3991
Step 14: 3991 + 307 = 4298
Step 15: 4298 + 307 = 4605
Step 16: 4605 + 307 = 4912
Step 17: 4912 + 307 = 5219

So, 307*17 = 5219
