Without delay, let's solve this. We've got 239 and we will be multiplying it by 13, that is, adding 239 to itself 13 times.
Step 1: 0 + 239 = 239
Step 2: 239 + 239 = 478
Step 3: 478 + 239 = 717
Step 4: 717 + 239 = 956
Step 5: 956 + 239 = 1195
Step 6: 1195 + 239 = 1434
Step 7: 1434 + 239 = 1673
Step 8: 1673 + 239 = 1912
Step 9: 1912 + 239 = 2151
Step 10: 2151 + 239 = 2390
Step 11: 2390 + 239 = 2629
Step 12: 2629 + 239 = 2868
Step 13: 2868 + 239 = 3107

So, 239*13 = 3107
