Sure thing! We've got 181 and we're gonna multiply it by 9. That's the same as adding 181 to itself 9 times.
Step 1: 0 + 181 = 181
Step 2: 181 + 181 = 362
Step 3: 362 + 181 = 543
Step 4: 543 + 181 = 724
Step 5: 724 + 181 = 905
Step 6: 905 + 181 = 1086
Step 7: 1086 + 181 = 1267
Step 8: 1267 + 181 = 1448
Step 9: 1448 + 181 = 1629

So, 181*9 = 1629
