Alright, let's solve this math problem step by step. First, we have the number 165. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 11. So, we're going to take the number 165 and add it to itself 11 times.
Step 1: 0 + 165 = 165
Step 2: 165 + 165 = 330
Step 3: 330 + 165 = 495
Step 4: 495 + 165 = 660
Step 5: 660 + 165 = 825
Step 6: 825 + 165 = 990
Step 7: 990 + 165 = 1155
Step 8: 1155 + 165 = 1320
Step 9: 1320 + 165 = 1485
Step 10: 1485 + 165 = 1650
Step 11: 1650 + 165 = 1815

So, 165*11 = 1815
