Alright, let's solve this math problem step by step. First, we have the number 424. 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 424 and add it to itself 10 times.
Step 1: 0 + 424 = 424
Step 2: 424 + 424 = 848
Step 3: 848 + 424 = 1272
Step 4: 1272 + 424 = 1696
Step 5: 1696 + 424 = 2120
Step 6: 2120 + 424 = 2544
Step 7: 2544 + 424 = 2968
Step 8: 2968 + 424 = 3392
Step 9: 3392 + 424 = 3816
Step 10: 3816 + 424 = 4240

So, 424*10 = 4240
