Alright, let's solve this math problem step by step. First, we have the number 859. 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 859 and add it to itself 13 times.
Step 1: 0 + 859 = 859
Step 2: 859 + 859 = 1718
Step 3: 1718 + 859 = 2577
Step 4: 2577 + 859 = 3436
Step 5: 3436 + 859 = 4295
Step 6: 4295 + 859 = 5154
Step 7: 5154 + 859 = 6013
Step 8: 6013 + 859 = 6872
Step 9: 6872 + 859 = 7731
Step 10: 7731 + 859 = 8590
Step 11: 8590 + 859 = 9449
Step 12: 9449 + 859 = 10308
Step 13: 10308 + 859 = 11167

So, 859*13 = 11167
