Alright, let's solve this math problem step by step. First, we have the number 1000. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 8. So, we're going to take the number 1000 and add it to itself 8 times.
Step 1: 0 + 1000 = 1000
Step 2: 1000 + 1000 = 2000
Step 3: 2000 + 1000 = 3000
Step 4: 3000 + 1000 = 4000
Step 5: 4000 + 1000 = 5000
Step 6: 5000 + 1000 = 6000
Step 7: 6000 + 1000 = 7000
Step 8: 7000 + 1000 = 8000

So, 1000*8 = 8000
