    What is 492 − 39?

    Answer

    492 − 39 =
    453

    With regrouping: 1 borrow — from the tens

    492 − 39 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)2 (was 2, now 12)
    −39
    453

    Column by column: 492 − 39

    • Ones: 2 is less than 9 — borrow 1 ten: tens 9 → 8; 12 − 9 = 3 — write 3.
    • Tens: after borrowing, 8; 8 − 3 = 5 — write 5.
    • Hundreds: nothing to subtract — write 4.

    492 − 39 = 453

    Second check: 492 − 453 = 39
