OK, let's crack this. We're given 166 and our task is to multiply it by 9. Essentially, we'll be adding 166 to itself 9 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

So, 166*9 = 1494
