Alright, let's solve this math problem step by step. First, we have the number 800. 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 800 and add it to itself 10 times.
Step 1: 0 + 800 = 800
Step 2: 800 + 800 = 1600
Step 3: 1600 + 800 = 2400
Step 4: 2400 + 800 = 3200
Step 5: 3200 + 800 = 4000
Step 6: 4000 + 800 = 4800
Step 7: 4800 + 800 = 5600
Step 8: 5600 + 800 = 6400
Step 9: 6400 + 800 = 7200
Step 10: 7200 + 800 = 8000

So, 800*10 = 8000
