    Here my problem is same, via normal LR method….

    1. 590 – 492 = 1_ _

    2. In ten digit 90 – 92 = 0_

    3. Now after borrow( for unit digit) 0 become 9(in ten digit)  and unit digit is 10-2 = 8

    4. But how I change hundred digit 5 – 4 in zero.

    chk ur solution, u didn’t mention how u make 1 to 0, u just make 9-9 = 0 in 9 after carry 1,
    <figure>2. Subtracting the second two digits (9 – 9) we get 0.

    590 – 492 = 1 0 _

    3. We can’t subtract the last digits 0 and 2. So we borrow 1 from our answer 10, so the calculated digits change to 9.

    590 – 492 = 9 _

    4. Next we subtract 10 – 2 to get 8.

    590 – 492 = 9 8</figure>
