Alright, let's solve this math problem step by step. First, we have the number 868. 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 868 and add it to itself 13 times.
Step 1: 0 + 868 = 868
Step 2: 868 + 868 = 1736
Step 3: 1736 + 868 = 2604
Step 4: 2604 + 868 = 3472
Step 5: 3472 + 868 = 4340
Step 6: 4340 + 868 = 5208
Step 7: 5208 + 868 = 6076
Step 8: 6076 + 868 = 6944
Step 9: 6944 + 868 = 7812
Step 10: 7812 + 868 = 8680
Step 11: 8680 + 868 = 9548
Step 12: 9548 + 868 = 10416
Step 13: 10416 + 868 = 11284

So, 868*13 = 11284
