Sure thing, let's get straight to it. We start with 165 and we're going to multiply it by 10, which means adding 165 to itself 10 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

So, 165*10 = 1650
