Sure thing, let's get straight to it. We start with 141 and we're going to multiply it by 11, which means adding 141 to itself 11 times.
Step 1: 0 + 141 = 141
Step 2: 141 + 141 = 282
Step 3: 282 + 141 = 423
Step 4: 423 + 141 = 564
Step 5: 564 + 141 = 705
Step 6: 705 + 141 = 846
Step 7: 846 + 141 = 987
Step 8: 987 + 141 = 1128
Step 9: 1128 + 141 = 1269
Step 10: 1269 + 141 = 1410
Step 11: 1410 + 141 = 1551

So, 141*11 = 1551
