Without delay, let's solve this. We've got 161 and we will be multiplying it by 10, that is, adding 161 to itself 10 times.
Step 1: 0 + 161 = 161
Step 2: 161 + 161 = 322
Step 3: 322 + 161 = 483
Step 4: 483 + 161 = 644
Step 5: 644 + 161 = 805
Step 6: 805 + 161 = 966
Step 7: 966 + 161 = 1127
Step 8: 1127 + 161 = 1288
Step 9: 1288 + 161 = 1449
Step 10: 1449 + 161 = 1610

So, 161*10 = 1610
