Alright, let's solve this math problem step by step. First, we have the number 581. 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 581 and add it to itself 13 times.
Step 1: 0 + 581 = 581
Step 2: 581 + 581 = 1162
Step 3: 1162 + 581 = 1743
Step 4: 1743 + 581 = 2324
Step 5: 2324 + 581 = 2905
Step 6: 2905 + 581 = 3486
Step 7: 3486 + 581 = 4067
Step 8: 4067 + 581 = 4648
Step 9: 4648 + 581 = 5229
Step 10: 5229 + 581 = 5810
Step 11: 5810 + 581 = 6391
Step 12: 6391 + 581 = 6972
Step 13: 6972 + 581 = 7553

So, 581*13 = 7553
