Question  Step 1  Step 2  Step 3 




 Start from the ones place
 In the ones place, since we cannot subtract 9 from 5, we borrow 1 from 3 and make it 2.
 In ones place we get 159 = 6
 In the tens place, since we have taken out 1 from 3, we have 31=2
 Since we cannot subtract 8 from 2, we borrow 1 from 5 and make it 4.
 In hundreds place, we have 53=1
