Alright, let's solve this math problem step by step. First, we have the number 349. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 13. So, we're going to take the number 349 and add it to itself 13 times.
Step 1: 0 + 349 = 349
Step 2: 349 + 349 = 698
Step 3: 698 + 349 = 1047
Step 4: 1047 + 349 = 1396
Step 5: 1396 + 349 = 1745
Step 6: 1745 + 349 = 2094
Step 7: 2094 + 349 = 2443
Step 8: 2443 + 349 = 2792
Step 9: 2792 + 349 = 3141
Step 10: 3141 + 349 = 3490
Step 11: 3490 + 349 = 3839
Step 12: 3839 + 349 = 4188
Step 13: 4188 + 349 = 4537

So, 349*13 = 4537
