Alright, let's solve this math problem step by step. First, we have the number 166. 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 166 and add it to itself 10 times.
Step 1: 0 + 166 = 166
Step 2: 166 + 166 = 332
Step 3: 332 + 166 = 498
Step 4: 498 + 166 = 664
Step 5: 664 + 166 = 830
Step 6: 830 + 166 = 996
Step 7: 996 + 166 = 1162
Step 8: 1162 + 166 = 1328
Step 9: 1328 + 166 = 1494
Step 10: 1494 + 166 = 1660

So, 166*10 = 1660
