Alright, let's solve this math problem step by step. First, we have the number 146. 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 146 and add it to itself 10 times.
Step 1: 0 + 146 = 146
Step 2: 146 + 146 = 292
Step 3: 292 + 146 = 438
Step 4: 438 + 146 = 584
Step 5: 584 + 146 = 730
Step 6: 730 + 146 = 876
Step 7: 876 + 146 = 1022
Step 8: 1022 + 146 = 1168
Step 9: 1168 + 146 = 1314
Step 10: 1314 + 146 = 1460

So, 146*10 = 1460
