Alright, let's solve this math problem step by step. First, we have the number 427. 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 427 and add it to itself 10 times.
Step 1: 0 + 427 = 427
Step 2: 427 + 427 = 854
Step 3: 854 + 427 = 1281
Step 4: 1281 + 427 = 1708
Step 5: 1708 + 427 = 2135
Step 6: 2135 + 427 = 2562
Step 7: 2562 + 427 = 2989
Step 8: 2989 + 427 = 3416
Step 9: 3416 + 427 = 3843
Step 10: 3843 + 427 = 4270

So, 427*10 = 4270
