Alright, let's solve this math problem step by step. First, we have the number 239. 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 239 and add it to itself 10 times.
Step 1: 0 + 239 = 239
Step 2: 239 + 239 = 478
Step 3: 478 + 239 = 717
Step 4: 717 + 239 = 956
Step 5: 956 + 239 = 1195
Step 6: 1195 + 239 = 1434
Step 7: 1434 + 239 = 1673
Step 8: 1673 + 239 = 1912
Step 9: 1912 + 239 = 2151
Step 10: 2151 + 239 = 2390

So, 239*10 = 2390
