Alright, let's solve this math problem step by step. First, we have the number 814. 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 814 and add it to itself 13 times.
Step 1: 0 + 814 = 814
Step 2: 814 + 814 = 1628
Step 3: 1628 + 814 = 2442
Step 4: 2442 + 814 = 3256
Step 5: 3256 + 814 = 4070
Step 6: 4070 + 814 = 4884
Step 7: 4884 + 814 = 5698
Step 8: 5698 + 814 = 6512
Step 9: 6512 + 814 = 7326
Step 10: 7326 + 814 = 8140
Step 11: 8140 + 814 = 8954
Step 12: 8954 + 814 = 9768
Step 13: 9768 + 814 = 10582

So, 814*13 = 10582
