OK, let's crack this. We're given 796 and our task is to multiply it by 13. Essentially, we'll be adding 796 to itself 13 times.
Step 1: 0 + 796 = 796
Step 2: 796 + 796 = 1592
Step 3: 1592 + 796 = 2388
Step 4: 2388 + 796 = 3184
Step 5: 3184 + 796 = 3980
Step 6: 3980 + 796 = 4776
Step 7: 4776 + 796 = 5572
Step 8: 5572 + 796 = 6368
Step 9: 6368 + 796 = 7164
Step 10: 7164 + 796 = 7960
Step 11: 7960 + 796 = 8756
Step 12: 8756 + 796 = 9552
Step 13: 9552 + 796 = 10348

So, 796*13 = 10348
