    What is 491 − 89?

    Answer

    491 − 89 =
    402

    With regrouping: 1 borrow — from the tens

    491 − 89 in a column. Above the columns: the values after borrowing — a crossed-out digit is replaced by the number above it; +10 marks a column that received a borrowed ten.
    8+10
    4 9(was 9, now 8)1 (was 1, now 11)
    −89
    402

    Column by column: 491 − 89

    • Ones: 1 is less than 9 — borrow 1 ten: tens 9 → 8; 11 − 9 = 2 — write 2.
    • Tens: after borrowing, 8; 8 − 8 = 0 — write 0.
    • Hundreds: nothing to subtract — write 4.

    491 − 89 = 402

    Second check: 491 − 402 = 89
