Alright, let's solve this math problem step by step. First, we have the number 860. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 10. So, we're going to take the number 860 and add it to itself 10 times.
Step 1: 0 + 860 = 860
Step 2: 860 + 860 = 1720
Step 3: 1720 + 860 = 2580
Step 4: 2580 + 860 = 3440
Step 5: 3440 + 860 = 4300
Step 6: 4300 + 860 = 5160
Step 7: 5160 + 860 = 6020
Step 8: 6020 + 860 = 6880
Step 9: 6880 + 860 = 7740
Step 10: 7740 + 860 = 8600

So, 860*10 = 8600
