OK, let's crack this. We're given 199 and our task is to multiply it by 13. Essentially, we'll be adding 199 to itself 13 times.
Step 1: 0 + 199 = 199
Step 2: 199 + 199 = 398
Step 3: 398 + 199 = 597
Step 4: 597 + 199 = 796
Step 5: 796 + 199 = 995
Step 6: 995 + 199 = 1194
Step 7: 1194 + 199 = 1393
Step 8: 1393 + 199 = 1592
Step 9: 1592 + 199 = 1791
Step 10: 1791 + 199 = 1990
Step 11: 1990 + 199 = 2189
Step 12: 2189 + 199 = 2388
Step 13: 2388 + 199 = 2587

So, 199*13 = 2587
